Fuel Injection Keeps Getting Better For St. Louis Motorists

St. Louis car owners know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.

Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved MPG.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.

Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage for St. Louis motorists as well as delivering less power to the engine.

Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice for St. Louis drivers. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance at St. Louis BDG in St. Louis. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.

Keep it Flowing With A Fuel Filter Replacement At St. Louis BDG

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 St. Louis Missouri use fuel filters.

For more information about your fuel filter, visit St. Louis BDG or come by our shop located at 1665 Scherer Pkwy. in St. Louis, Missouri 63303.
Please call 636-946-5900 to make an appointment.

Generally speaking there’s not a lot of dirt in our St. Louis Missouri 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 sedan 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 sedan 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 St. Louis service advisor at St. Louis BDG. We’ll be happy to explain.

Clean Fuel Equals Clean Performance For St. Louis Drivers

Hello, St. Louis motorists. Let’s talk fuel filters. Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the engine.

St. Louis drivers don’t need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better an engine will run.

Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your sedan ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.

The harder your fuel filter works, the more often it needs to be replaced. Check with your sedan owner’s manual or St. Louis BDG to find out how often it should be serviced and how long you can expect it to last. You should change it before it becomes clogged. Your St. Louis BDG technician can help you with recommended replacement schedules.

If your fuel filter becomes clogged, your engine will sputter when you drive at Missouri highway speeds or when you accelerate rapidly. A clogged filter allows enough fuel to run the car at low speeds around town in St. Louis, but when you need a higher flow of fuel for faster speeds, or if you need a sudden burst of fuel, you just won’t be able to get it through the filter.

A clogged filter is actually dangerous. If you need to accelerate suddenly out of the path of danger, you just won’t have the power to do it.

Fuel filters have a bypass valve. When the filter becomes clogged, the valve allows some fuel to bypass the filter so the engine can keep running – just not enough to be running well.

That means, though, that dirty, unfiltered fuel is entering your engine. Instead of clogging up your filter, that dirt is now getting into your fuel injectors, where it can cause serious damage. Fuel injectors are expensive; fuel filters are cheap. It doesn’t seem like a difficult choice for St. Louis car owners.

Fuel filters are the epitome of preventive maintenance. They are cheap and easy to change, but neglecting them can lead to pricey repair bills. Some fuel filters are inside the fuel tank and cannot be routinely serviced – your honest St. Louis BDG tech will be able to tell you if this applies to your vehicle.

Good car care for St. Louis motorists means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered at St. Louis BDG and in every owner’s manual and have your vehicle regularly inspected. It may save you money by preventing costly repairs, but it will also repay you in improved gas mileage, safety and peace of mind.

Fuel System Cleaning at St. Louis BDG in St. Louis for Better Performance

A fuel injector is a valve that delivers fuel to a vehicle’s engine. It has to deliver the precise amount of fuel, to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.

Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.

The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.

Vehicles have one fuel injector for each cylinder in the engine. Your vehicle’s control computer constantly monitors the engine and various sensors in the vehicle and adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle’s engine.

Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel efficiency and loss of engine performance.

So it’s vital to keep your fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name Missouri fuel companies also deliver a more consistent quality of fuel than do bargain stations in the St. Louis area.

The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.

Check your owner’s manual or St. Louis BDG in St. Louis to find out how often you should change your fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle, your filter will need to be changed more often.

You can also purchase cleaners that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won’t be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use.

If your fuel injectors are gummed up, you can get a professional deep cleaning service at St. Louis BDG in St. Louis that will result in better fuel efficiency and improved vehicle performance.

Good car care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.

Maintaining Your Diesel in St. Louis

Your browser does not support video

Diesel engines have been used extensively in Europe and Asia for many years. They haven’t been as common in St. Louis because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more St. Louis motorists driving diesel-fueled vehicles on the road, especially in passenger cars and SUV’s.

Diesels are popular in St. Louis because they get better gas mileage than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. And if you associate diesel engines with black smoke, then you’re not up with the times. That smoke is a thing of the past.

Diesels don’t produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in Missouri as for other vehicles.

Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegetable oil or from cellulosic waste like wood chips and sawdust. In St. Louis, we may soon see bio-diesel produced from algae. These fuel sources will lessen St. Louis car owners’ dependence on fossil fuels and may even become truly renewable and sustainable.

Diesel-powered vehicles perform as well as other passenger vehicles, also. Most Chesterfield people don’t notice a difference in driving one or the other. If you haul heavy loads or tow a trailer in Clayton, however, the diesel is a definite improvement.

So, you may be asking, if diesels are so great, why don’t all St. Louis car owners drive them? Surely there are disadvantages you haven’t told me about. That’s true. Diesel engines are heavier than gas engines, and they cost more in Missouri. The better MPG of the diesel engine is partially offset by the higher purchase price.

Because of higher fuel prices, diesel engines used to be more expensive to drive in St. Louis. But now, with higher volatility in the prices of both gasoline and diesel fuel in Missouri, that cost difference is less definitive. Whether a diesel or gas engine is more expensive for St. Louis drivers depends now on the current price of fuel in Missouri and how many miles you drive.

Consider also that diesel-powered vehicles have a high resale value in the St. Louis area, and the costs of owning and operating a diesel vs. a gas-powered vehicle in Missouri becomes a real toss-up.

Preventive auto maintenance for diesel vehicles has also become similar to that of gas-fueled vehicles in recent years. The major difference is that diesels require cleaner fuel, air and oil, so their filters are more expensive in St. Louis than those for gasoline engines. The engine air filter must be changed more frequently as well.

The costs for car care and repairs in St. Louis are similar. Wait, you may be thinking, but you just told me that filters are more pricey and have to be changed more regularly. True, but that is offset by the fact that diesel engines have a much longer lifetime than gasoline engines. So if you are the type of owner who prefers to hang on to a vehicle for a long time, you will be more than rewarded with a diesel engine.

So if you have been looking for St. Louis BDG auto advice on whether to switch to a diesel vehicle or stay with a gas-powered one, then we hope this helps. The answer as to which type of vehicle is better is that it depends on the St. Louis driver and their driving habits. Now that you know the facts, you can make an informed choice based on your own priorities and needs.

The St. Louis BDG Guide to Saving Fuel: Car Weight

Your browser does not support video

The team at St. Louis BDG in St. Louis and Missouri car owners are all talking MPG right now. Better gas mileage. Fewer emissions. St. Louis car owners want to save the environment and their pocketbooks.

And we all know—or should know—that preventive maintenance will help maximize fuel efficiency. But is there something more St. Louis auto owners can do? After all, some of us St. Louis folks can’t cut back on our driving, and others would like to do more to economize.

Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get from St. Louis to Granite City. And that means buying more gas in St. Louis and producing more emissions.

Of course, your sedan’s weight isn’t negotiable. And you can’t do much about the weight of your passengers. And this isn’t an article about diet and exercise.

But look around your sedan. Are you hauling a bunch of unnecessary weight around Missouri? Do you really need your golf clubs every time you leave your St. Louis home? Store sports equipment in the garage. Load it when you need it and store it when you don’t. Who knows? The extra exercise just might reduce the other type of weight in your vehicle.

The same goes for anything else in your car: make-up kits, music collections, extra electronics, spare clothing; whatever your particular extras may be. Pack it when you need it; store it when you don’t.

Clean out your St. Louis. You’d be surprised how much weight you’re lugging around St. Louis in plain old junk. Toss old papers, leftover food, and regular old dirt. Even if it’s not a lot of weight, you’ll feel better when you get into your car. A good cleaning is also part of good car care.

Now, don’t toss stuff you really do need. You do need that spare tire—the one in your trunk. And a kit of emergency essentials is not a bad idea. But just carry around the day-to-day essentials. You can pack a more extensive kit and store it in your garage, then toss it in your St. Louis when you go on a longer trip, but you don’t have to lug it around all the time. After all, are you a driver? Or are you a junk chauffeur?

Lose the junk and save some money in St. Louis

Deep Clean Your Fuel System At St. Louis BDG

Having trouble with your fuel system? Bring your sedan into St. Louis BDG for a check up.

1665 Scherer Pkwy.
St. Louis, Missouri 63303
636-946-5900

In today’s St. Louis BDG auto post, we’re talking about fuel system cleaning. The first thing to know is how vital it is to have a clean fuel system. St. Louis drivers need fuel to go, and the cleaner the fuel system, the more efficiently the fuel will burn. That means more power and better gas mileage.

A clean fuel system saves money for St. Louis motorists at Missouri gas stations. We guess you could say, it all starts and ends at the pump. One of the most important things St. Louis drivers can do to keep their sedan 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 in Missouri can actually be more expensive for St. Louis auto owners in the long run. Now, most cars on Missouri expressways 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 sedan 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 be dangerous. So St. Louis drivers should have their fuel filter changed when recommended. Check your owner’s manual or ask your honest St. Louis BDG service specialist 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 at St. Louis BDG in St. Louis 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 essential for St. Louis auto owners 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 hurt gas mileage.

It is important for the fuel system proper, but there are a couple other things that will help keep your sedan 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 at St. Louis BDG to make sure that system is working properly for St. Louis car owners and the breather filter needs to be replaced if it’s dirty as well.

Do all these things and your sedan engine’s air and fuel will be as clean as possible. You’ll get much better fuel economy and better power.

St. Louis BDG: Good Service And Good Fuel Economy

Most St. Louis and Clayton car owners want to save on gas and seek our advice on improving gas mileage. At St. Louis BDG, we are frequently asked, however, if it is really worth the extra effort. Just how much money can St. Louis auto owners actually save?

The US government has a website dedicated to helping us use less fuel. It presents the cost savings in a way St. Louis car owners can relate to and is relevant for all vehicles. Let me give you an example: Having your sedan engine properly tuned, can save up to 4%. If you’re paying three-fifty for a gallon of gas in St. Louis, you could save fourteen cents a gallon.

St. Louis BDG: Good Service And Good Fuel Economy

In today’s St. Louis BDG article, we’re focusing on the things you can do to improve your sedan fuel economy driving around Missouri. We’ll tell you the potential savings per gallon of gas at three dollars and fifty cents, and we’ll show a chart that also shows the savings at three and four dollars.

DOLLARS PER GALLON $3.00 $3.50 $4.00
TUNE UP 4% .12 .14 .16

The next item is replacing a clogged engine air filter. Your engine needs enough air to burn fuel efficiently for the best fuel economy. A clean air filter means you get plenty of air. The fact that the air’s clean protects your engine. That can save you up to ten percent or thirty-five cents a gallon.

DOLLARS PER GALLON $3.OO $3.50 $4.00
AIR FILTER 10% .30 .35 .40

Fixing a faulty oxygen sensor can improve economy by up to forty percent. That’s a whopping dollar forty in savings per gallon. Bring your car to St. Louis BDG in St. Louis and we’ll check your oxygen sensor.

DOLLARS PER GALLON $3.00 $3.50 $4.00
FAULTY O2 SENSOR 40% 1.20 1.40 1.60

Chances are that if your oxygen sensor is kaput your check engine light will come on. Now, there’s any number of things that could cause your check engine light to come on besides oxygen sensor problems. But if it’s on, get it checked out as soon as you can at St. Louis BDG.

Here’s an easy one for astute St. Louis car owners. Inflate your tires to the recommended pressure. That could save you three percent or eleven cents a gallon. Even a little drop in pressure will bring down your fuel economy, so check your tires every week.

DOLLARS PER GALLON $3.00 $3.50 $4.00
TIRE INFLATION 3% .09 .11 .12

Your sedan vehicle manufacturer has recommended a specific weight of motor oil. The recommendation is based on engine design and will give you the best protection. Using a heavier weight could cost one to two percent in reduced fuel economy, or up to seven cents a gallon.

DOLLARS PER GALLON $3.00 $3.50 $4.00
RIGHT GRADE MOTOR OIL 2% .06 .07 .08

Here’s one that’s free for St. Louis car owners that  want to save money: Take it easy when you drive. Aggressive driving (we’ve all seen this on St. Louis roads), rocketing away from stop lights, standing on the brakes, punching it for lane changes – really takes a toll on your gas mileage.

Cutting out aggressive driving around St. Louis can save five percent or eighteen cents a gallon. Now on the freeway it gets really costly: thirty three percent or a buck sixteen a gallon. Think about that – and leave a little earlier.

DOLLARS PER GALLON $3.00 $3.50 $4.00
DRIVE AGRESSIVELY – MIN. 5% .15 .18 .20
DRIVE AGGRESSIVELY – MAX. 33$ .99 1.16 1.32

A related item is exceeding the speed limit. For example, if the speed limit is sixty miles per hour on your St. Louis interstate,  an additional five miles will cost seven percent or twenty-five cents a gallon. Fifteen miles per hour will cost you upwards of eighty cents a gallon.

DOLLARS PER GALLON $3.00 $3.50 $4.00
SPEED LIMIT – MIN. 7% .21 .25 .28
SPEED LIMIT – MAX. 23% .69 .81 .92

The last thing we’ll talk about is excess weight. Our sedans tend to accumulate a lot of things and the weight adds up. Clear out the trunk and only haul stuff when you really need it. For every one hundred pounds you can save two percent or seven cents a gallon.

Sorry honey, your brother can’t come with. It’d cost an extra thirty cents a gallon.

Fuel Filter Service in St. Louis Missouri

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 St. Louis BDG can help you know what’s scheduled to be taken care of.

Some of us in St. Louis Missouri 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 St. Louis Missouri 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 St. Louis Missouri 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 St. Louis Missouri service advisor at St. Louis BDG 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 St. Louis Missouri service center has your back. When you’re motivated to maintain your vehicle’s performance and to reduce operating costs, you’ll think of St. Louis BDG as your ally – and maybe even your memory.
