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.

Herndon 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 McLearen Shell in Herndon. We have the tools and chemicals to do the job right. Our friendly and knowledgeable team at McLearen Shell can remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently.

You'll find McLearen Shell at 3043 Centreville Road in Herndon, VA 20171. Or just give us a call at (703) 318-7744 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 McLearen Shell can tell you when your car is scheduled for a fuel system cleaning.

The McLearen Shell Guide to Tire Specs

You know you need new tires, but you're not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the Herndon service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.

Tire size can be confusing for many Herndon drivers. There's so much on the side of the tire, and it's hard to keep straight.

Even though there's a lot on a tire - if you know what it all means, it's actually more helpful than confusing for Herndon tire shoppers. Let's start with the size number.

For example, let's say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters - the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio - the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high performance tires will have a lower number.

The R signifies it's a radial tire. And 16 is the rim or wheel size in inches.

The 92 is the load rating index - it's the load carrying capacity of a tire. The higher the number, the more it can safely carry. Your empty vehicle can be safe with a lower number, but you'll need a higher rating if you routinely haul heavy loads around Herndon. The next letter is the speed rating. Not all tires sold in Herndon are speed rated. The ratings generally follow the alphabet: the further up the alphabet, the higher the speed rating - with the exception of H - it comes between U and V (don't ask why).

There's a lot of fine print that most Herndon area drivers probably need a magnifying glass to read. But there are a couple of other large print items of interest. One is the tread type: highway, mud and snow, all season, severe snow, etc.

And then there are the Uniform Tire Quality Grading System markings. The first is a tread wear index. 100 is the base line - a lower number is poorer and a higher number is better. All things being equal, a tire rated 200 would wear twice as long, on a government test track, than one rated at 100. These wear grades are only valid within the manufacturers product line - you can't compare with others. And it's important to note that a lower rating might be just what you want - a high performance, sticky tire has a softer rubber compound and won't wear as long, but boy, will it take those corners on twisting VA roads.

The next is a traction grade. This measures the tire's ability to stop on wet pavement in government tests. A - the best, B - intermediate, C - acceptable.

Temperature grade measures a tire's resistance to heat buildup in government tests. A, B and C - from best to acceptable.

It's safe for Herndon drivers to go with the vehicle manufacturers original equipment recommendations that came on your car. But if you want to make adjustments, you'll now be better equipped to communicate with your friendly and knowledgeable McLearen Shell tire professional.

Automotive Tips from McLearen Shell: When to Replace Your Wiper Blades

There are several important factors that go into how often Herndon drivers should replace their wiper blades. Of course, the more you use your wipers, the faster the blades will wear out – especially if you use them on an icy windshield. Whether it’s a lot of bugs and road grime from VA freeway driving or lots of wet weather – your blades get a work out and start to wear.

But your wiper blades break down even when they aren’t used frequently. They are damaged by sunlight and temperature changes as well. The rubber in the blades can dry out and crack and eventually fall apart. Check your wipers: If they’re not doing their important job, have them replaced at McLearen Shell in Herndon.

Talk to your McLearen Shell service advisor about how you drive - we can counsel you on the optimal blades for your needs.

Time for a Brake (Brake Pad Replacement)

Stop! It's one of those things your vehicle has to do consistently and reliably.  That's why brake maintenance is vitally important, worthwhile for you to make sure stays up to date.

A brake system has many components. If your vehicle has disc brakes, they have pads that make contact with the rotors (the metal discs).  Those pads usually have a metal back, and the part that presses against the discs is made of a material which provides friction to stop the vehicle. Because of that friction, the pads are expected to wear down and eventually the rotors will, too.  But the pads usually are the part that will need to be replaced more often. But how do you know when it's time?

There are several signs, one of which is when your brakes squeak or make a high-pitched sound when you step on the brake pedal.  Many newer vehicles also have sensors on the brake pads.  When the pads get worn down to a certain point, the sensor will tell the vehicle's computer to turn on a light on the instrument panel.  When that light comes on, it's time to have your service facility check out what's going on.  If you don't know what that light looks like, ask your service advisor or look it up in the owner's manual.

Some vehicles also give you a reminder based on the distance you've traveled. It may be a message that displays on the dash or a light that illuminates. 

Your best bet is to have your vehicle regularly serviced at one shop you trust.  They will keep a record of your brake maintenance Then, when you take your vehicle in for oil changes or other routine things, they'll check your brakes for wear.  Sometimes you'll only need pads, but you may also need rotors or other parts replaced.  Oh, and you need pads replaced in pairs. That way stopping power will be equal on both sides and your vehicle won't pull in one direction. 

Brakes make up a key part of your vehicle's safety systems.  Keep them in good shape and they'll be able to stop your vehicle when you press down that pedal.

Fuel Filter Service in Herndon, VA

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 McLearen Shell can help you know what's scheduled to be taken care of.

Some of us in Herndon, VA, 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 Herndon, VA, roads is over nine years. When vehicles 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 vehicle will just run better too.

A clogged fuel filter can't let enough fuel through. You might notice at first that your vehicle is running fine around town but struggles or sputters on the Herndon, VA, 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 vehicles. 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 Herndon, VA, service advisor at McLearen Shell can tell you as well. It's usually around 30,000 miles (50,000 kilometers) 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 Herndon, VA, service center has your back. When you're motivated to maintain your vehicle's performance and to reduce operating costs, you'll think of McLearen Shell as your ally - and maybe even your memory.
