Fuel Saving Tip: Car Weight And Your MO Driving

Weight is the enemy of fuel economy. Everyone from here to Fenton knows this makes sense.

Some of us in the Fenton area carry a bunch of unnecessary weight, and I’m not talkin’ what you see in the mirror.

pickup Weight 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 Fenton, and everywhere else.

Lose the junk and save some money.

…And you really only need one of those spare tires.

Fuel Injection: It Keeps Getting Better for Marlborough Drivers

Marlborough auto owners know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your pickup 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 pickup engine.

Direct injection engines burn fuel more efficiently than conventional pickup 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.

Fuel Injection: It Keeps Getting Better for Marlborough DriversWhy the big difference in power? Direct injection systems allow fuel to be squirted into the pickup 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.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the pickup 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 as well as delivering less power to the engine.

Marlborough motorists should understand that fuel injectors are not cheap to replace. Direct injection fuel injectors are even more costly. 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. 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. 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, Marlborough auto owners will enjoy better fuel economy and their fuel injectors will last for a long time.

Carsmart Auto Service Often Asked About Premium vs. Regular Gas

Marlborough motorists 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 Marlborough, MO 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 auto manufacturer recommends.

For help identifying the type of gasoline your engine needs, come by Carsmart Auto Service in Marlborough:

Marlborough car owners should read their owner’s manuals carefully to see if it’s acceptable to use lower grades. With some cars in Marlborough, MO it is; the engine control computer can adapt. Marlborough car owners will lose some performance, but won’t do damage. With other engines, using a lower grade of fuel could result in serious and pricey damage; so you don’t want to save a couple of bucks at the pump only to pay it out a hundred fold at your Marlborough repair shop.

Your car will run best on the type of gas recommended by the manufacturer.

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 Marlborough car owners any additional performance or better gas mileage.

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 pickup into Carsmart Auto Service. It may be a sign that you need a tune-up or some other repair.

In times of expensive gas prices, most Marlborough auto owners are conscious of making their fuel dollar go further as we drive around MO. 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 MPG possible.

Fuel System Cleaning at Carsmart Auto Service for Better Performance

Hi Marlborough motorists. Let’s talk fuel injectors. 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 pickup 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.

Fuel System Cleaning at Carsmart Auto Service for Better PerformanceVehicles 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 for Marlborough drivers.

So it’s to Marlborough drivers’ advantage to keep their 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 fuel companies also deliver a more consistent quality of fuel to Marlborough auto owners than do bargain Dupo area service stations.

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.

Marlborough drivers should check their owner’s manual to find out how often they should change their 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 between Marlborough, East Carondelet and Ballwin , your filter will need to be changed more often.

You can also purchase cleaners at Carsmart Auto Service 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 Carsmart Auto Service in Marlborough that will result in better MPG 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.

Your car’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 Marlborough auto owners 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 important parts of your fuel system.

Some Marlborough drivers are interested in buying fuel system cleaners that they can pour into your gas tank.

Clean Fuel

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 pickup engine.

Marlborough auto owners 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 your pickup 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 pickup 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.

Clean Fuel – Clean Performance for Marlborough DriversThe harder your fuel filter works, the more often it needs to be replaced. Check with your owner’s manual to find out how often it should be serviced and how long you can expect it to last. Marlborough motorists should change it before it becomes clogged. Your courteous Carsmart Auto Service service specialist can help you with recommended fuel filter replacement schedules.

If your fuel filter becomes clogged, your pickup engine will sputter when you drive at highway speeds or when you accelerate rapidly. A clogged filter allows enough fuel to run the car at low speeds around town in Marlborough, 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.

Marlborough motorists take note: 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.

Fuel filters are the epitome of preventive maintenance. They are cheap and easy to change, but neglecting them can lead to expensive repair bills for Marlborough auto owners. Some fuel filters are inside the fuel tank and cannot be routinely serviced – your courteous Carsmart Auto Service service specialist will be able to tell you if this applies to your vehicle.

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

Fuel Filter Service in Marlborough MO

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 Carsmart Auto Service can help you know what’s scheduled to be taken care of.

Some of us in Marlborough MO 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 Marlborough MO 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 Marlborough MO 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 Marlborough MO service advisor at Carsmart Auto Service 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 Marlborough MO service center has your back. When you’re motivated to maintain your vehicle’s performance and to reduce operating costs, you’ll think of Carsmart Auto Service as your ally – and maybe even your memory.

Fuel Injection Basics For Marlborough

All modern Marlborough vehicles come with fuel injection systems, so it’s a topic Dupo auto owners need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount, at the right time; to be mixed with air and burned in the engine.

So how many fuel injectors does your car have? There’s one for each cylinder. So four, six or eight for most folks in Marlborough, MO. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.

Carsmart Auto Service can help Dupo car owners with a fuel injector cleaning service. What’s the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It’s vital that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn’t get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about dirty fuel – how does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It’s tempting to shop for bargains in  Dupo with fuel prices as high as they are, but major brands in the Marlborough, MO area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is a vital component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it’s clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It’s critical to replace the fuel filter when your vehicle manufacturer recommends it. That’s part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Marlborough motorists are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There’s no room for dirt and gum in a precision part like that.

There are a lot of good products available in Marlborough, MO that can clean fuel injectors. They’re best used by Marlborough drivers to prevent fouling in the fuel injectors. Many can’t clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Carsmart Auto Service in Marlborough. But putting the cleaner in the fuel tank after you’ve had Carsmart Auto Service take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your pickup may be ready for a fuel injector cleaning.
