Give Your Engine Clean Fuel with a New Fuel Filter from McLearen Shell

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

That's why all vehicles, including vehicles, come equipped with a fuel filter. The 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 McLearen Shell in Herndon.

If your fuel filter is clogged, the vehicle 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 vehicle engine running but doesn't protect it from  contaminated fuel.

Herndon drivers may find that they need to change their fuel filter at McLearen Shell more frequently as their vehicle 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 parts and to maintain performance.

Automotive Tips from McLearen Shell: Knowing When Your Timing Belt Should Be Replaced

The timing belt in your engine controls the opening and closing of the intake and exhaust valves. Herndon drivers need to replace it on a schedule to avoid failure.

Timing belts are very difficult to get to, requiring quite a bit of labor to access. Timing belt replacement is one of the more expensive maintenance services, but the cost at McLearen Shell to correct an engine damaged by a broken timing belt is much, much more.

The timing belt has a tensioner to help maintain proper belt tension. The tensioner should be replaced along with the timing belt and any idler pulleys at the vehicle manufacturer’s specified service interval. Your McLearen Shell service advisor can help you with the timing belt.

Give us a call.

The McLearen Shell Guide to Custom Wheels

If you're interested in customizing the wheels and tires on your vehicle, there are a few things you should know first.

Most importantly, the wheels you buy need to fit your vehicle. Not all wheels are created equal. Too many Herndon drivers have bought a set of wheels that caught their eye, then, after going to the work of mounting them, have found that the wheels don't fit right and the tires rub against the vehicle when they turn or go over a bump.

To ensure a proper fit, you can consult with your McLearen Shell tire professional. He/she can also help you find tires that are suited to your driving habits as well as your vehicle. You may find their auto advice invaluable, and you'll probably be happier with your new wheels once you purchase them.

But if you just have to have that set of wheels, and you're willing to pay for them, you can modify your vehicle to fit the wheels. Again, you should seek a knowledgeable professional's help ahead of time. For example, if you want a bigger set of wheels on your pickup truck, you can get a suspension lift so they will fit the truck. A professional Herndon custom wheel shop, like McLearen Shell, can help you get the work done right.

The anti-lock brakes and stability control system on your vehicle are engineered to work with a particular height of tire. This is another reason you should be careful when purchasing custom wheels in Herndon. The new wheel and tire combo needs to match the height of the tires that came with your vehicle.

Your car's computer gauges your speed by the revolution of your tires and sends commands to the brakes and traction control based on that speed. If you put larger or smaller tires on your vehicle, your computer is calculating the wrong speed and, consequently, sending incorrect commands to the brakes and traction control. This can have serious consequences as it may result in damage to your vehicle or, worse, an accident.

If you change the size of your wheels, you need to get your engine's computer reprogrammed at McLearen Shell to accommodate the new tire size. New wheels shouldn't just fit your vehicle, they should also fit your lifestyle. There are hundreds of styles and sizes to choose from. You should do a little research about which wheels and tires will best fit your personality, give you the performance you want and meet your handling needs. We're not saying you shouldn't personalize your ride, we just want you to be happy with the result. Talk to us at McLearen Shell in Herndon.

After all, good vehicle care isn't just about preventive maintenance. It's also about making good choices.

Severe Service Requirements

A lot of Herndon drivers have asked whether or not they should use their severe service maintenance schedule, which is listed in their vehicle's  owner's  manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for over 30 years and is a speaker, a trainer and a writer.

Cricket says there's so much confusion on this topic because, "Most owner's manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service.' Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement and transmission service be done more often: either in fewer miles or in less time."

Foreign and domestic vehicle manufacturers create a specific schedule for each vehicle they manufacture. So there isn't one generic schedule that applies to all vehicles. In addition to your owner's manual, Herndon automotive repair centers (including McLearen Shell) subscribe to information services that provide the auto maintenance schedules for every vehicle - so they can help Herndon drivers know when to take care of needed services. Below is a typical definition for severe service.

• Most trips are less than four miles/six and a half kilometers
• Most trips are less than 10 miles/16 km and outside temperatures are below freezing
• You drive regularly in very hot VA weather
• The engine is at low speed most of the time (not on the freeway)
• Stop and go driving
• You drive in in dusty or muddy conditions
• You routinely tow a trailer, haul heavy loads or carry a car-top carrier around Herndon

It's common sense for Herndon drivers: Just a few minutes at higher speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than 10 miles when it's very cold, don't allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to break down faster. Dusty and muddy driving around Herndon means that more dirt will get past the air filter to contaminate the fuel system and engine oil.

The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving habits. Look at your owner's manual or talk with your McLearen Shell service advisor who can help you know which schedule to follow.

Here is what a fleet manager said recently: "Since city miles are generally tougher on vehicles than highway miles, we use the manufacturer's severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science."

Make an honest evaluation of your driving habits. Unless you do mostly VA highway driving in moderate weather, you'll likely have a fairly good amount of severe service mixed in. Some Herndon drivers just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.

Ask us for help evaluating your driving and service needs.

Busting Automotive Myths in Herndon, VA

Myths passed around our Herndon, VA community start with a grain of evidence and are then built up with a lot of imagination and very elastic logic. And the internet is a breeding ground for automotive myths. Some bloggers recall the vehicles of yesteryear and declare their modern decedents to be virtually maintenance free and that anyone who says otherwise is out to rip you off.

To get the truth about auto myths you hear around the Herndon area, come over to McLearen Shell.

Let's examine a couple of the more popular rants and look at the truth behind them.

The first one is that the chassis no longer needs lubrication for suspension, steering and the driveline. They declare that anyone who has charged you for lubrication is a charlatan.

The truth on which this myth is based is that many new vehicles come from the factory with sealed joints and cannot be greased. However, there are still some grease points on many cars around Herndon. A grease fitting may have been installed in conjunction with a repair. And most trucks and truck-based SUVs driving in Herndon still require chassis lubrication. This is because they are more heavy duty and proper greasing is still required to keep them going.

Another common rant you'll hear around Herndon is that modern vehicles don't need tune-ups. That depends on your definition of a 'tune-up', which has changed as technology has progressed. Before engine control computers, electronic ignition and fuel injection, a tune up meant replacing mechanical parts that wore out. Service technicians at McLearen Shell would manually adjust fuel and air mix and timing. When these adjustments were off, spark plugs would foul and need to be replaced.

This definition just doesn't apply to modern vehicles. Service centers like McLearen Shell generally consider a tune-up to be the major service visit, recommended by your manufacturer, every 30,000 miles (50,000 kilometers) or so.

Of course you can't lubricate a sealed joint. Of course you can't adjust a carburetor if your car doesn't have one. You probably don't need to change spark plugs every year if your manufacturer says they can go 30,000 miles (50,000 kilometers). What are these bloggers getting so worked up about?

The danger with these modern-day myths is they prevent people in our local Herndon community from taking care of the routine preventive auto maintenance that manufactures recommend. Check out this partial list of things you still need to do to take care of your car. How many of them are really any different today than they were 20 or 30 years ago?

Oil change, cooling system service, transmission service, tire balancing, tire rotation, wheel alignment, suspension service, power steering service, proper tire inflation, brake service, differential service, battery maintenance, engine air filer, PCV valve, breather element, fuel filter, belts, hoses, timing belt, windshield wipers . . .

You get the picture. Your vehicle is still a machine that needs to be maintained. And, hey, your service advisors at McLearen Shell have always adapted to keep pace with automotive technology. Next time you come across an angry voice about your car care, talk to your Herndon service advisor at McLearen Shell, or do some research of your own.
