Give Your Engine Clean Fuel With A New Fuel Filter From Parkway Automotive

Thursday, August 29th, 2013

Your truck requires plenty of clean fuel to run. If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your truck engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts fuel efficiency and performance as you drive around Conway, Arkansas. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

That’s why all vehicles, including trucks, come equipped with a fuel filter somewhere between the engine and the fuel tank. Give Your Engine Clean Fuel With A New Fuel Filter From Parkway AutomotiveThe job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at Parkway Automotive in Little Rock .

If your fuel filter is clogged, the truck engine can’t get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your truck engine running, but doesn’t protect it from contaminated fuel.

You may find that you need to change your fuel filter at Parkway Automotive more frequently as your truck ages. Over the years, additional sediment and rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect expensive parts and to maintain performance and fuel economy.

Fuel Saving Tip: Little Rock Tune Up

Friday, June 21st, 2013

Have you ever gone to Conway, Arkansas to listen to an orchestra? The musicians take the stage early and tune their instruments. Each individual instrument must be in tune, but the critical thing is for the entire orchestra to be in tune with each other. That’s why they tune up together.

Fuel Economy Now this is no surprise; I’m going to relate the orchestra to your car. Your engine has many component systems that each need to be working properly. And the components need to be working in sync, all timed up together in order for the engine to work efficiently.

We call this, (ta-da) a tune-up. When an orchestra’s out of tune you get a bad concert. When your vehicle’s out of tune you get bad performance and bad fuel economy.

So check your owner’s manual for recommended tune-up intervals. Or ask your Little Rock service advisor at Parkway Automotive what he thinks.

…Just be careful not to say you want to make beautiful music together – that kinda makes us uncomfortable.

Fuel Filter Service in Little Rock Arkansas

Friday, April 26th, 2013

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 Parkway Automotive can help you know what’s scheduled to be taken care of.

Some of us in Little Rock Arkansas 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 Little Rock Arkansas 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 Little Rock Arkansas 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 Little Rock Arkansas service advisor at Parkway Automotive 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 Little Rock Arkansas service center has your back. When you’re motivated to maintain your vehicle’s performance and to reduce operating costs, you’ll think of Parkway Automotive as your ally – and maybe even your memory.

Fuel Injector Cleaning At Parkway Automotive

Thursday, March 28th, 2013

In very simple terms, a fuel injector is a valve that squirts fuel into your truck 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 Cabot, Arkansas, Bryant, Arkansas, and Ferndale, Arkansas interstates.

Fuel Injector Cleaning In Cabot, Arkansas, Bryant, Arkansas, and Ferndale, ArkansasMost fuel injectors for gas engines are known in the Conway, Arkansas 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 auto makers have recently introduced gas direct injection systems on some engines. They are now available at some Conway, Arkansas 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 economy for gas-poor Cabot, Arkansas, Bryant, Arkansas, and Ferndale, Arkansas drivers. Arkansas motorists can expect to see more of it in the future.

High temperatures
under your truck hood and variations in Conway, Arkansas 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 Little Rock drivers keep their fuel injectors clean.

Parkway Automotive 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 truck fuel system means that you will spend less on gas, enjoy strong performance and prevent costly Conway, Arkansas repair bills down the road.

Parkway Automotive Often Asked About Premium vs. Regular Gas

Thursday, February 14th, 2013

People in Little Rock Arkansas 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 Little Rock Arkansas 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 Little Rock Arkansas service center:
Parkway Automotive
708 Kirk Road
Little Rock, Arkansas 72223
501-821-6111

Read your owner’s manual carefully to see if it’s acceptable to use lower grades. With some cars in Little Rock Arkansas 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.

Your car will run best on the grade of gasoline 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 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 truck into Parkway Automotive. 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 Little Rock Arkansas. 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.

Professional Fuel System Cleaning

Tuesday, January 29th, 2013

Getting enough 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.

You can buy fuel system cleaners that you just pour into your gas tank that can help maintain an already clean fuel system, but can’t do a major cleaning. For that, you need to see Parkway Automotive. They have the tools and chemicals to do the job right. Parkway Automotive can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently.

You’ll find Parkway Automotive at 708 Kirk Road in Little Rock, Arkansas 72223. Or just give us a call at 501-821-6111 to schedule an appointment.

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

And, as with all maintenance, it can help prevent costly repairs that can happen because you didn’t take preventative steps. Check with your service technician at Parkway Automotive and see when your car is scheduled for a fuel system cleaning.

Direct Fuel Injection Update From Parkway Automotive

Tuesday, October 30th, 2012

For those of you in Little Rock Arkansas 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 truck 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 Parkway Automotive 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 Parkway Automotive

Thursday, October 25th, 2012

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 Little Rock Arkansas use fuel filters.

For more information about your fuel filter, visit Parkway Automotive or come by our shop located at 708 Kirk Road in Little Rock, Arkansas 72223.
Please call 501-821-6111 to make an appointment.

Generally speaking there’s not a lot of dirt in our Little Rock Arkansas 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 truck 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 truck 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 Little Rock service advisor at Parkway Automotive. We’ll be happy to explain.

Engine Air Filter From Parkway Automotive

Tuesday, August 28th, 2012

You may have found yourself in the following situation: You go to get your oil changed and the service adviser at Parkway Automotive 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 Parkway Automotive 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 Little Rock right now? Can you see any smog? Is it full of pollen? How about dust? Anyone in Arkansas 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.

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. 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.
