In very simple terms, a fuel injector is a valve that squirts fuel into your car engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected car driving down Biltmore, Weaverville, and Arden/Fletcher highways.
Most fuel injectors for gas engines are known in the Hendersonville automotive community as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.
A few manufacturers have recently introduced gas direct injection systems on some engines. They are now available at some Hendersonville dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.
Although more complicated, direct injection technology promises greater power with improved fuel efficiency for gas-poor Biltmore, Weaverville, and Arden/Fletcher drivers. North Carolina motorists can expect to see more of it in the future. High temperatures under your car hood and variations in Hendersonville gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.
When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor fuel economy and loss of power. So it’s important for Asheville drivers keep their fuel injectors clean.
The Organic Mechanic service center can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.
Proper maintenance of your car fuel system means that you will spend less on gas, enjoy strong performance and prevent costly Hendersonville repair bills down the road.

Fuel Saving Tip: Slow Down Around Asheville
Posted January 15, 2013 9:27 AM
There's not much we can do about the price of gas in Asheville North Carolina, but we do quite a bit about how much we use as we're driving on our Asheville streets.
Our driving habits can dramatically affect our fuel economy.
The first thing we can do is watch the 'go-pedal'. Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don't need to floor it. That can save you hundreds of dollars a year.
Go a little slower on the freeway to Hendersonville. Once you're going more than sixty-five miles an hour your fuel economy starts to drop dramatically. Leave early so you don't need to rush to be on time. And cruise control is your friend – steady speed uses less gas.
Plan errands ahead. Make fewer trips by combining errands.
Hey at current gas prices, a lead-foot might as well be a gold foot.

Diesel Maintenance For North Carolina
Posted November 28, 2012 10:28 AM
At The Organic Mechanic we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV's. But our North Carolina friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there're nearly as many diesel powered passenger cars as there are gasoline.
Here's who's announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in North Carolina.
You may ask, why has it taken so long getting to North Carolina and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that North Carolina diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up North Carolina to the engines the rest of the world's been enjoying for a long time.
Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there's none of that black smoke we used to see.
Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.
You may also have heard a lot in the news about bio-diesel. The exciting thing about diesels is that they're not limited to fossil fuels. They can run on fuel made from vegetable oil. There are refineries that make diesel fuel from cellulosic waste like woodchips from lumber mills. There's even this cool new process where a special strain of algae is used to convert carbon dioxide, water and sunshine into bio-diesel. That's still a ways off, but you can see that diesel can become a sustainable source of fuel.
And, there are not a lot of trade off's with diesel in terms of performance. A modern passenger car diesel is very smooth, quiet and quick. Most folks wouldn't notice any difference. For those who tow trailers and haul heavy loads, diesels will be an improvement.
Now diesel engines are heavy duty, so they cost more than gas engines. But they get better fuel economy – so the break-even point is largely dependent on the difference between North Carolina gas and diesel prices at the pump and how many miles you drive. And diesels have a higher resale value.
Now, let's get back to diesel maintenance. You have to keep in mind that most of the new diesels are just coming in, or will be over the next couple of years, so we don't have the maintenance schedules to make direct comparisons yet.
But going off what we already have in North Carolina, we can expect fluid drain intervals to be similar to gasoline engines. Diesels do require very clean fuel, air and oil, so their filters are much higher capacity than gasoline filters and cost more. The engine air filter needs to be changed more frequently as well.
Repair costs are similar. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system, and so on. And the payoff for you, if you're the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for hundreds of thousands of miles.

Higher Mileage Service Intervals For Asheville
Posted August 22, 2012 9:47 AM
The government mandates a lot of equipment on cars for the Asheville North Carolina area: emission devices and control computers; safety equipment like airbags; and crash worthiness requirements. All of this is great for the motoring public in Asheville North Carolina, but it does add quite a bit to the price of a new car.
Because new cars are more expensive, people are driving their old cars longer. The average car is now over nine years old. 68% of vehicles on the road have more than 75,000 miles/120,000 kilometers. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge - but they need a little help to keep on going.
Some owner's manuals don't specify service requirements at higher mileage. That doesn't mean it doesn't have to be done. In fact, it's more important than ever to stay on top of routine maintenance for cars with more than 120,000 miles/190,000 kilometers. Just extend regular service intervals out: for instance a service that's recommended every 24,000 miles/38,000 kilometers should be performed at 24,000 mi/38,000 km; 48,000 mi/77,000 km; 72,000mi/116,000 km, 96,000 mi/154,000 km; and on and on.
Because of the additional stress older engines experience, the severe service maintenance schedule may be more appropriate than the regular schedule. Watch for leaks - seals and gaskets dry out over time and do not hold the fluids as well as they used to. It is also time to make sure you have a good technician. There are some services and replacements that are scheduled after you put some clicks on the odometer, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course.
Check for unusual sounds, smells or the way your car feels. These could be hints that trouble is brewing. Better to catch it early before it turns into a costly repair. Regular wash and wax will help maintain your car's appearance. One of the things you can do to really help your high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, and transmission and power steering fluids that are formulated for cars that have a higher mileage.
High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older engines are dirtier inside - and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection. Come into The Organic Mechanic for a checkup.
Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high kilometer vehicles. So once you hit around 50,000 mi/80,000 km, consider stepping up to high mileage formulations. The fluids cost a bit more than standard fluids because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road.
It does cost more to properly maintain a higher mileage vehicle - but it's much cheaper than a new car payment!

Alternative Fuel Vehicles In Asheville North Carolina
Posted August 2, 2012 10:51 AM
Let's talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions to our Asheville environment, automakers will have a number of alternatives for us very soon.
For instance, Flex Fuel vehicles are already available in the Hendersonville area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn.
The benefits are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower fuel economy and that when gas prices are low, E85 can be more expensive than straight gasoline.
You should only use E85 if you have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.
Diesel engines have been around the Hendersonville area for a long, long time. Modern diesels are very refined and fuel efficient. Diesel fuel can be made from renewable sources like vegetable oil, too. Diesel fuel from algae and sunlight is reported to be pretty close to being commercially viable.
There are also a number of natural gas vehicles on our Hendersonville roads. Gasoline engines are adapted to run on compressed natural gas. It's less expensive than gasoline and burns very cleanly. You can even refill it with a special pump from your gas line at home.
Natural gas engines don't make as much power and don't get as good of mileage, but they cost less per mile to run. The big inconvenience is that the tank that holds the compressed natural gas takes up a lot of room; even your whole trunk! And there may not be places to refuel on a road trip from Hendersonville.
Plug-in electric vehicles are now available in our Hendersonville area. Battery technology is the limiting factor right now. Electric cars have a limited range and are really best for use close to home. As battery technology advances, electric cars will perform closer and closer to conventional power plants.
That brings us to hybrids. There are a bunch of hybrids on our Hendersonville roads, with more to come. Hybrid technology combines internal combustion engines with electric motors.
A mild hybrid has a regular gas or diesel engine that's assisted by the electric motor. The electric motor can propel the vehicle by itself up to a certain speed under gentle acceleration. There are mild hybrids in full-sized pickups and SUVs. They deliver city fuel economy similar to their highway ratings.
A full hybrid will rely primarily on the electric motor for power. It'll have a small gas or diesel engine that generates electricity for the batteries.
Another breakthrough technology is hydrogen fuel cells. Fuel cell vehicles use hydrogen to generate electricity. Several global car makers have prototypes on the road. The appeal is that the only thing that comes out of the tail pipe is water vapor. It'll take some time to build a national infrastructure of hydrogen fueling stations before there's widespread use.
A quick word about safety around hybrid and electric vehicles. Unlike the battery in your current family car, these carry enough voltage to kill you. Never mess around under the hood or with the batteries or electrical wiring. Your Hendersonville service technician at The Organic Mechanic is trained to safely disable the flow of electricity before performing maintenance or repairs on the vehicle.
Hybrids are really not do-it-yourself vehicles unless you're specifically trained on hybrid systems.

Finding Vehicle Recall Information In Asheville North Carolina
Posted July 5, 2012 3:01 PM
No matter how well they're made, cars in Asheville North Carolina will have design or manufacturing problems.
And when the government thinks a problem is really serious for people in Asheville North Carolina, they require the manufacturer to issue a recall notice and fix the car free of charge. The manufacturer then tries to contact everyone in Asheville North Carolina who owns that type of car to get the recall work done.
These recalls always affect safety, so take them seriously. It's easy to see if a vehicle's being recalled.
The government has links on its websites, or just visit AutoNetTV for links.
There are many websites with free recall information and searches. There's CarFax, AutoByTel and the DMV.
Recalls are serious, but not all that common. But sometimes there are less significant issues, and for these, manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like The Organic Mechanic how to repair a frequent or difficult problem.
The pros get updated information through subscription plans, also available in consumer versions for a reasonable cost.
So when vehicle recalls occur, get the work done, and keep you and yours safe.

Direct Fuel Injection Update From The Organic Mechanic
Posted June 20, 2012 1:51 PM
For those of you in Asheville North Carolina who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.
For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.
So what are the differences from a conventional engine?
The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.
With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.
First, the fuel is squirted in at hundreds of times more pressure, so it's atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.
Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can't do its job as well. That means less power and worse fuel economy for your car and can lead to damaged fuel injectors.
Replacing fuel injectors isn't cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we're talking mortgage payment-range to replace a set of diesel injectors.
A professional fuel system cleaning from The Organic Mechanic gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they'll last a long, long time.

Keep it Flowing With A Fuel Filter Replacement At The Organic Mechanic
Posted May 18, 2012 10:19 AM
The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around Asheville North Carolina use fuel filters.
For more information about your fuel filter, visit The Organic Mechanic or come by our shop located at 568 Haywood Rd in Asheville, North Carolina 28806. Please call 828-255-2628 to make an appointment.
Generally speaking there's not a lot of dirt in our Asheville North Carolina auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That's because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your car is five years or older, it can actually have a fair amount of sediment built up.
That just means that the fuel filter has to work harder as your car ages. It'll get clogged sooner and need to be replaced more often.
A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That's because enough fuel is getting through around town, but when you need more fuel for speed, enough just can't get through the filter. Obviously, that could be dangerous if your car or truck can't get enough power to get you out of harm's way.
For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.
This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don't want to cause them damage just because you didn't spend a few bucks to replace a fuel filter.
You know, in a way, the fuel filter can be the poster child for preventive maintenance. It's a little part, it's simple and it's cheap to take care of. But if it's neglected, it could lead to thousands of dollars of repair bills.
Those auto service schedules in your owner's manual are there for a reason. If ever you don't understand a recommended service, just ask your Asheville service advisor at The Organic Mechanic. We'll be happy to explain.

Fuel Filter Service in Asheville North Carolina
Posted May 8, 2012 12:28 PM
There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn't seem right.
Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember, because it is a long list, but your service center at The Organic Mechanic can help you know what's scheduled to be taken care of.
Some of us in Asheville North Carolina really don't look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.
But automotive maintenance is all about prevention, and addressing small problems before they get big. Let's take the fuel filter for example.
You may not know this but the median age for private vehicles on our Asheville North Carolina roads is over nine years. When cars get older, five years or so, they've accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation – is the lowly fuel filter: a very inexpensive part that doesn't cost too much to replace. And your car'll just run better too.
A clogged fuel filter can't let enough fuel through. You might notice at first that your car is running fine around town, but struggles or sputters on the Asheville North Carolina freeway or when you accelerate. Enough fuel can't get through to meet the demands of higher speed. If it gets bad enough your engine might just shut off or not start at all, which could be dangerous.
Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We've already talked about how expensive that can be.
The fuel filter is even very important for newer cars. The fuel is still dirty even if there isn't rust in the tank. It's just that the fuel filter will need to be changed more frequently as the vehicle gets older.
How often should you change your fuel filter? Check your owner's manual. Your Asheville North Carolina service advisor at The Organic Mechanic can tell you as well. It's usually around thirty thousand miles or so. Ask if it's time for a full fuel system cleaning as well. They often go hand in hand.
It's good to know that your Asheville North Carolina service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of The Organic Mechanic as your ally - and maybe even your memory.

Fuel Saving Tip: Car Weight And Your North Carolina Driving
Posted March 28, 2012 9:51 AM
Weight is the enemy of fuel economy. Everyone from here to Arden/Fletcher knows this makes sense.
Some of us in the Arden/Fletcher area carry a bunch of unnecessary weight, and I'm not talkin' what you see in the mirror.
Guys; sports equipment and tools. Ladies; well, just take a look around the passenger compartment and trunk. I think my car has about forty-five pounds of French fries on the floor.
All that extra weight wastes gas as you drive between here and Arden/Fletcher, and everywhere else.
Lose the junk and save some money.
...And you really only need one of those spare tires.

The Organic Mechanic Often Asked About Premium vs. Regular Gas
Posted March 1, 2012 1:51 PM
People in Asheville North Carolina often ask the question: "Will using premium gas make my car run better?" The answer is simple. But first, let's talk about what exactly premium gasoline is.
Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations around Asheville North Carolina also carry a mid-grade that falls in between the two. The octane range for the different grades of gas varies by region due to altitude differences.
Engines require different octane ratings because of design differences. For example, turbocharged engines usually require premium gas.
There's a sticker on your gas tank filler lid that tells you the minimum octane rating your manufacturer recommends.
For help identifying the type of gasoline your engine needs, come by our Asheville North Carolina service center: The Organic Mechanic 568 Haywood Rd Asheville, North Carolina 28806 828-255-2628
Read your owner's manual carefully to see if it's acceptable to use lower grades. With some cars in Asheville North Carolina it is; the engine control computer can adapt. You’ll lose some performance, but won't do damage. With other engines, using a lower grade of fuel could result in serious damage; so you don't want to save a couple of bucks at the pump only to pay it out a hundred fold at the repair shop.
Today's computer controlled vehicles are optimized to run well on the recommended grade of fuel. Using a higher grade than is recommended will not give you any additional performance or better fuel economy.
Regulations require detergents for all grades of gasoline, so your engine will have the same protection, regardless of the grade of fuel you use. If you do hear some knocking or pinging from your engine, take it seriously and get your car into The Organic Mechanic. It may be a sign that you need a tune-up or some other repair.
In times of high gas prices, we're all conscious of making our fuel dollar go further as we drive around Asheville North Carolina. Be sure to use the right gas for your car. Keep your tires properly inflated and your vehicle well maintained and you will get the best fuel economy possible.

Fuel Saving Tip: Check Engine Light
Posted February 8, 2012 2:26 PM
A question for our Asheville North Carolina motorists: How long have you been enjoying the romantic glow of your check engine light?
Hey, it's not there to create ambiance; it's a warning that something's wrong. When your check engine light comes on get it checked at a capable Asheville North Carolina service station.
Many conditions that cause the check engine light to come on affect fuel economy. Some very dramatically.
Always make sure you tighten your gas cap until it clicks. A loose gas cap can cause a false sensor reading that'll make the check engine light come on.
If your date's eyes are smoldering in the reflected glow of the check engine light, try to think of all the gas money you'll save by getting it fixed. Give us a call when you are ready: 828-255-2628

How Do You Save Gas In Asheville North Carolina?
Posted December 15, 2011 10:22 AM
No one in Asheville North Carolina likes high fuel prices. But if one good thing has come about, it's that people are really focused on how to reduce their fuel consumption. North Americans literally drive billions of miles less each month during times of high fuel prices. But we still need to drive, so it makes sense to try and increase our fuel economy however we can.
Let's look at a real life example of one of our AutoNetTV producers. He has one of those really big SUVs. Lots of kids and horses to haul around, you know. His family was planning a four day camping trip. Here's what he did to cut his fuel costs:
First, he installed a new, high flow engine air filter. Then he had his service center change his oil, flush his cooling system and service his front and rear differentials along with the transfer case. He also had a fuel system cleaning, replaced his PCV value and breather element. He also made sure his tires were up to the recommended pressure.
Now this cost several hundred dollars. But keep in mind, it all needed to be done anyway – it was all scheduled, and some of the work was overdue.
So he headed out, loaded with nine people and pulling a ton of trailer with everything needed for four days of camping. When the trip was over, he had turned in the best fuel economy he had ever gotten on that vehicle. It had improved 25 percent. He saved $48.00 on that trip alone. And the savings keep on coming every day.
Here's a quick summary of what you can do to save fuel in Asheville North Carolina. First get caught up on your routine maintenance. Nearly every scheduled service item can save you some fuel. If its time for a tune-up, git'er done. That's a big item.
If your check engine light is on, have your Asheville North Carolina service center at The Organic Mechanic figure out why and fix it. Check engine problems can be real gas wasters.
Proper tire pressure and wheel alignment can really help as well. Try not to carry around a bunch of stuff. An extra hundred pounds can cost a mile per gallon.
Now you may not want to hear this, but the single biggest fuel waster for most people is their right foot. Zooming away from stop lights and hot rod lane changes really waste fuel. Take it easy, don't speed and plan ahead.
Finally, you may have noticed that we haven't mentioned any magic pills or devices that will double your mileage. That's because there aren't any. Some may help a bit, but there are a lot are scams.
Do some research and check with your service advisor at The Organic Mechanic before spending your hard earned cash.

Fuel Saving Tip: Dirty Oil In Your Asheville car
Posted November 3, 2011 1:26 PM
If you're a quart low in your car, there isn't enough motor oil to lubricate your engine properly. The extra friction causes drag that reduces fuel economy while you're driving around the Hendersonville area.
The same goes for dirty oil; it doesn't reduce friction properly. The result is you get to watch those numbers at your local Hendersonville gas pump rolling higher and higher.
The transmission also needs the proper amount of clean fluid to do its work. When it's in need of service, the transmission drags your fuel economy down.
So keep it clean and give yourself a fighting chance.

Deep Clean Your Fuel System At The Organic Mechanic
Posted October 25, 2011 10:49 AM
Having trouble with your fuel system? Bring your car into The Organic Mechanic for a check up. 568 Haywood Rd Asheville, North Carolina 28806 828-255-2628
Today we're talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.
A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.
So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they've had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That's the fuel filter's job.
When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner's manual or ask your service advisor if your fuel filter is due for replacement.
The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.
It's real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can't do that if they're dirty. Dirty fuel injectors really rob power and waste fuel.
It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it's burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it's dirty.
The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it's dirty as well.
Do all these things and your engine's air and fuel will be as clean as possible. You'll get much better fuel economy and better power

Engine Air Filter From The Organic Mechanic
Posted October 19, 2011 9:25 AM
You may have found yourself in the following situation: You go to get your oil changed and the service adviser at The Organic Mechanic recommends you get a new engine air filter. You say yes, but because you didn't know what an air filter is or what it does, but you were too embarrassed to ask.
First of all, you did the right thing by getting a new one. And, you should never be too embarrassed to ask for more information from any of our The Organic Mechanic staff. It's your money and you have a right to understand what you're paying for.
Let's review what an air filter does:
Air is the focus of this discussion. What is the air like outside in Asheville right now? Can you see any smog? Is it full of pollen? How about dust? Anyone in North Carolina with hay fever can tell you that there's plenty in the air that you can't see. Well, it's the engine air filter's job to clean that air before it goes into your engine, to mix with the fuel and be burned. Without an engine air filter, the inside of your engine would be extremely dirty from all the gunk that was burned in the cylinders.
The Organic Mechanic 568 Haywood Rd Asheville, North Carolina 28806 828-255-2628
In fact, for every gallon of gas you burn, your engine needs 12,000 gallons of air. That little filter does a very big job. It's no wonder that the air filter gets dirty and needs to be replaced. Think about a vacuum cleaner. When the bag gets full of dust and dirt, the vacuum doesn't clean as well. It can't move enough air to create good suction. A clogged engine air filter is the same way - the engine can't get enough air to burn the fuel efficiently. That means less power and wasted gas.
That's why your manufacturer has recommended that you change your filter at regular intervals. Of course the conditions you drive in will affect how quickly the filter gets dirty. If you drive where it's very dusty or where there's lots of pollen or pollution, you may need to change the filter sooner. The filter is easy to check visually, so your service technician can quickly make the call. He might recommend immediate replacement, or simply let you know that it is getting close and that you'll need to replace it soon - like at your next oil change.
Because a severely dirty air filter hurts your fuel economy, many people find that a new air filter pays for itself in gas savings before the next oil change. They also make premium air filters that have been proven to increase your horsepower and torque.

Fuel Injectors
Posted September 29, 2011 7:03 AM
The last new car sold with a carburetor in North America rolled out of the dealership in 1990. Since then, all new vehicles have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injection is a much more precise way of delivering fuel than carburetors. That translates into better fuel economy and power. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.
A few auto makers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure - hundreds of times the pressure of port injection systems. Although more complicated, direct injection technology promises greater power with improved fuel economy, so we can expect to see more of it in the future.
As you can see, the level of precision required of your fuel injectors is very high. They need to be operating properly in order for your car to run right.
High temperatures under your hood and variations in gas quality cause fuel injectors to become fouled with wax, dirt, and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. The design of each engine requires a specific spray pattern from the fuel injector that might be altered when the injector is dirty. When injectors are dirty, the fuel doesn't burn as efficiently resulting in poor fuel economy and loss of power. So it is important to keep your fuel injectors clean.
Skilled service technicians at The Organic Mechanic in Asheville can perform a fuel system service for you. (Visit http://www.organic-mechanic.com/contact-us.asp.) That is a fuel system service - not just fuel injector cleaning. That is because the fuel has a lot of ways to become dirty or contaminated between the gas tank and the fuel injector. A fuel system service starts with a fuel filter replacement. This filter cleans the gas as it leaves the tank. The various parts of the fuel intake system need to be cleaned from time to time to remove harmful gum, deposits and varnish. Finally, the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.
Your Arden/Fletcher area service center uses a process for cleaning your fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing.
