Fuel System Cleaning at Car Doctor



Is your vehicle sometimes hard to start early in the morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your vehicle's fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy.

Most Oklahoma City vehicles have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.

Some Oklahoma City residents are interested in buying fuel system cleaners that they can pour into their gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning. For that, you need to see Car Doctor. Car Doctor has the professional tools and chemicals to really do a complete service.

Car Doctor uses a process that gives your vehicle a deep, professional fuel system cleaning. You need to remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. After a professional fuel system cleaning, you'll notice more power, better fuel economy and reduced exhaust emissions.

The cleaners also help prevent rust and corrosion in your fuel system and lubricate engine parts.

Fuel system cleaning is just one of those recommended service items that help keep your vehicle running strong. As with all maintenance, it can help avoid repairs that often result from not taking the right preventive steps. Oklahoma City residents will notice the difference in how well their vehicle runs. Check with your friendly and knowledgeable pros at Car Doctor to see when your vehicle is scheduled for a fuel system cleaning.

An ounce of prevention really is worth a pound of cure for Oklahoma City vehicles.

Introduction to Diesels for Oklahoma City, Oklahoma



Something you're going to be hearing a lot about around Oklahoma City, Oklahoma, is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.

Most people in Oklahoma are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven't been available in Oklahoma City, Oklahoma. But that's about to change.

In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Oklahoma City, Oklahoma, so we are now ready to start seeing more diesel options offered over the next few years.

Why are so many Oklahoma City drivers interested in diesel engines? Well first off, diesel fuel is more energy dense. There's more power in a barrel of diesel fuel than there is in a barrel of gasoline. The result? Better performance and improved fuel economy.

Diesel powered vehicles get about 20 percent better fuel economy. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold in Oklahoma City with diesel engines?

If you think back to the late 1970's and early 1980's, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels sold in Oklahoma have evolved considerably.

They are quiet, clean – and powerful. They're so refined that many Oklahoma City drivers can't even tell they're riding in a diesel powered vehicle. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.

Another thing the Oklahoma City green crowd takes advantage of is the use of bio-diesel in diesel vehicles. Bio-diesel is made from vegetable oil – even recycled cooking oil from Oklahoma City restaurants. There is a lot of buzz about hybrid cars in Oklahoma. Look to diesel-electric hybrids in years to come to make a good idea even better.

Every year, manufacturers introduce new diesel models. Look for diesels in domestic light trucks, SUVs and passenger cars. Import brands have plans to bring more of their outstanding diesel engines to Oklahoma as well.

New Oklahoma City diesel owners need to know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it's important to keep your fuel system clean with a diesel.

The good news is that Car Doctor in Oklahoma City is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.

When we tell you to look for more diesels on Oklahoma City streets, you won't be looking for smoky tail pipes as a clue. You also won't be listening for that familiar big rig rattle. And, you certainly won't be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.

Fuel Filter Replacement



Hello Oklahoma City resident! You would never like to drink a glass of mud, right? Well, your vehicle feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter's job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won't start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your vehicle will still run. But, then the contaminated fuel can clog your fuel injectors and allow particles into your engine.

A vehicle with a partially clogged fuel filter might run well around Oklahoma City, but sputter and strain on the because it's starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive in Oklahoma and the gas you buy. If you drive a lot on dirt or gravel roads in rural Oklahoma, your fuel filter will have a harder time keeping the fuel clean.

And, we hate to say it, but buying the cheapest gas from bargain stations sometimes means dirtier fuel that'll clog the filter sooner. Major brands tend to be cleaner and certainly have higher levels of detergent additives.

Of course, manufacturers recommend intervals for changing the fuel filter. But, it's a little more complicated than that for Oklahoma City residents. Some manufacturers stopped listing recommended intervals for fuel filter replacement or have very long intervals like every five years or 80,000 miles (130,000 kilometers). So you may need to look to other sources for recommendations. Vehicles older than six or seven years are especially at risk because they have had time for dirt and rust to build up in the fuel tank. A clean fuel filter keeps the gas flowing. Even a partially clogged filter puts added strain on the vehicle fuel pump. That can shorten its life and result in repair.

As is often the case, spending a little money now on something as inexpensive as a fuel filter can save money for Oklahoma City residents down the road by improving and preventing repairs. At Car Doctor in Oklahoma City, we can check your fuel filter. It is better than fixing a burned-out vehicle fuel pump or ruined fuel injectors.

Don't Be Fuelish

If you smell gasoline in your vehicle, pay attention to your nose. That's because it has an important message for you.

Newer vehicles should never have a gasoline smell inside. One of the most dangerous conditions can come when your fuel line system has a leak or multiple leaks. Vehicles with fuel injectors are under pressure, meaning a crack or small hole in a fuel line can allow vaporized fuel to escape, sometimes around hot engine parts. Gasoline vapor and hot metal? You see the problem.

One of the most common causes of a gasoline smell inside a vehicle is a fuel tank leak. The gas tank can rot or be punctured by road debris. A Car Doctor technician can evaluate the condition of your fuel tank and suggest either repair or replacement.

Fuel injectors can develop small leaks around their seals or O-rings. Those can deteriorate over time as the material they are made of gets old and less flexible. A technician can replace those parts.

Modern vehicles contain something called a charcoal canister. It gathers evaporating gasoline vapors from inside your fuel tank and prevents them from venting out to the atmosphere. If that canister has a leak, you'll smell it. One hint that you have a problem is the Check Engine light may come on.

You may have a leak in your fuel tank vent hose. Or you may be smelling gasoline simply because your gas cap is loose, the cap is faulty or—yes this does happen—your gas cap is missing altogether.

Consider the dangers of gasoline fumes seriously. Inhaling them can be bad for your health or they may start a fire. Don't fool with fuel; have gasoline odors checked out right away.

Higher Mileage Service Intervals for Oklahoma City



Oklahoma City drivers have probably noticed that the government mandates a lot of equipment on cars: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the motoring public in the Oklahoma City area, but it does add quite a bit to the price of a new car.

Because new cars are more expensive, Oklahoma City residents 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 outline service requirements and schedules at higher mileage. Of course, that doesn't mean it doesn't have to be done. In fact, it's more important than ever for Oklahoma City drivers to stay on top of routine auto 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; 72,000 mi/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. If you don't already have one, it is more important than ever to get a good technician, like any one of the automotive professionals on our team at Car Doctor. 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 for Oklahoma City vehicle owners that trouble is brewing. Better to catch it early before it turns into repair. Regular wash and wax will help maintain your car's appearance. One of the things Oklahoma City drivers can do to really help a high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, transmission fluids and power steering fluids that are formulated for cars that have higher mileage.


High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older vehicle 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 Car Doctor in Oklahoma City for a checkup.

Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high mileage 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 in Oklahoma City 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 for  vehicle owner's to properly maintain a higher mileage vehicle in Oklahoma City - but it's much cheaper than a new car payment!

Professional Fuel System Cleaning



Getting adequate fuel to your engine is very important for performance, fuel economy and safety. In order to accomplish this, your fuel system needs to be clean.

Today's production cars have fuel injectors, rather than a carburetor. The injectors need to be cleaned from time to time in order to deliver the fuel with the correct pressure, spray pattern and volume.

Oklahoma City drivers can buy fuel system cleaners that you pour into your gas tank to help maintain an already clean fuel system; however, they can't do a major cleaning. For that, you need to see Car Doctor in Oklahoma City. We have the tools and chemicals to do the job right. Our friendly and knowledgeable team at Car Doctor can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently.

You'll find Car Doctor at 1217 N.W. 5th St in Oklahoma City, Oklahoma 73106. Or just give us a call at 405-232-1949 to schedule an appointment.

You'll enjoy more power, better fuel economy and reduced exhaust emissions. The cleaners also help prevent rust and corrosion in your fuel system and lubricate engine parts.

And, as with all maintenance, it can help prevent repairs that can happen because you didn't take preventative steps. Our advisors at Car Doctor can tell you when your car is scheduled for a fuel system cleaning.

Car Doctor Often Asked About Premium vs. Regular Gas

Oklahoma City residents 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 Oklahoma City, Oklahoma, 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 vehicle manufacturer recommends.

For help identifying the type of gasoline your engine needs, come by Car Doctor in Oklahoma City.

Fuel Injectors



The last new American vehicles sold in Oklahoma City with a carburetor rolled out of the Oklahoma dealerships in 1990. Since then, all new vehicles here in Oklahoma City, and nationally, 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 injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for Oklahoma City drivers. 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 vehicle manufacturers 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 Oklahoma drivers can expect to see more of it in the future.

As Oklahoma City residents can see, the level of precision required of fuel injectors is very high. It's important that they operate properly in order for your vehicle to run right.

High temperatures under your hood and variations in Oklahoma City 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 vehicle fuel injectors clean.

Skilled service technicians at Car Doctor in Oklahoma City can perform a fuel system service for you. 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 Oklahoma City gas pump and your fuel injectors. A fuel system service at Car Doctor 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 for you and deliver the right amount of fuel at the right time.


Our pros at Car Doctor use a process for cleaning your vehicle fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing. Proper maintenance of your fuel system means that you will enjoy strong performance and prevent repairs down the road.

Engine Air Filter from Car Doctor

Many Oklahoma City drivers have found themselves in the following situation: They go to get their oil changed and their friendly service advisor at Car Doctor recommends a new engine air filter. They say yes, but don't know what an air filter is or what it does.

If this has happened to you, rest assured that you did the right thing by getting a new one. But you should never be too embarrassed to ask your Car Doctor service advisor for more information. It's your vehicle and you have a right to understand what you're paying for.

Let's review: "What does an air filter do?"

Air is the focus of this discussion. What is the air like outside in Oklahoma City right now? Can you see any smog? Is it full of pollen? How about dust? Anyone in Oklahoma with hay fever can tell you that there's plenty in the air that you can't see. Well, the engine air filter's job is to clean that air before it goes into your vehicle engine, to mix with the fuel and be burned. Without an engine air filter, the inside of your vehicle engine would be extremely dirty from all the gunk that was burned in the cylinders.

In fact, your engine needs 12,000 times as much air as fuel for it to run. 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 vehicle engine can't get enough air to burn the fuel efficiently. That means less power and reduced fuel economy.

That's why your owner's manual has recommended that you change your filter at regular intervals. Of course the Oklahoma City conditions you drive in will affect how quickly the filter gets dirty. If you drive in Oklahoma 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 friendly and knowledgeable Car Doctor service advisor 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 vehicle air filter hurts your vehicle, many Oklahoma City residents find that a new air filter pays for itself in better fuel economy before the next oil change. They also make premium air filters that have been proven to increase your horsepower and torque. If more power is important to you, a high performance air filter is some of the cheapest horsepower you can buy.

The better your car breathes, the better it runs - kind of like people. And don't worry - if you have a question or don't understand a recommendation just ask your Car Doctor service advisor.

Service to Improve Fuel Economy

The price of gas in Oklahoma has got people in Oklahoma City talking. It seems that Oklahoma City folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy.

First let's start with how we drive around Oklahoma. People in Oklahoma City may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster, too.

Another thing Oklahoma City drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we drive an extra five ... ten . . . twenty ... over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave a little bit earlier, save some money and arrive more relaxed.

Oklahoma City drivers can also try and combine all of their errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow, you can save some time and money.

Using your cruise control can save money too. Driving in Oklahoma at a constant speed really improves fuel economy. Be sure to only use your cruise control under safe conditions; you can look in your owner's manual for some good tips on using your cruise control.

Did you know that reducing the weight in your vehicle saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry a lot of stuff around Oklahoma City that you do not need in the vehicle. If you live in Oklahoma where there is snow and ice, clear it off your vehicle; it adds weight and messes with aerodynamics too.

Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going;  just take it easy for a few minutes.

Be sure to get a new gas cap if yours leaks or is worn.

Now, let's start talking mechanical. Bottom line - the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in improved fuel economy before your next oil change - and will keep saving you after that.

A clean, well-maintained fuel system really pays big dividends. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power, so drivers in Oklahoma City can't go wrong with that.

Some of us ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.

And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don't overlook the routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your vehicle manufacturer’s recommended service intervals in the owner's manual, or ask your Car Doctor service advisor for the schedule.

Don't forget your tires. Underinflated tires waste gas. And if your wheels are out of alignment, you won't get the fuel economy you need.

None of these things are very complicated or expensive for people in Oklahoma City to stay on top of. When you maintain your car properly, you save gas today and prevent repairs tomorrow.
