Talk to McLearen Shell About New Shoes for Your Vehicle

Custom wheels are one way that Herndon folks express themselves and personalize their vehicle. But they aren't as cheap and easy as sticking decals on your back window. There are several factors that need to be considered, including cost, the fit of the wheel, modifications that will have to be made to the vehicle, how the new wheels and tires will affect the operation of the vehicle, your driving habits and, of course, the style of the wheels. Most Herndon drivers start with the last factor: the style of the wheels. But that should be the last thing we choose.

When considering custom wheels, you should first carefully consider your budget. Some wheels may require adjustments to your vehicle suspension system, brakes, or traction systems. You need to know what you can afford before you start shopping or get your heart set on a particular type of wheel.

There are three basic ways you can change your wheels. First, you choose a wheel that is already the same size as the ones on your vehicle. Second, you can choose larger wheels and third, you can choose smaller wheels. Mounting wheels that are the same size as the ones already on your car sounds easy enough. But even though the wheel may be the same diameter as your current wheels, that doesn't mean it will fit your vehicle. Besides diameter, wheels also have an offset. This is the measurement from the inside edge of the wheel to the point at which it bolts on. If your new wheel does not have the same offset as your current wheels, your vehicle tires can rub on the inside or outside of the wheel well. This can lead to blowouts, uneven tread wear and other mechanical problems.

The tire and wheel professionals in Herndon at McLearen Shell on 3043 Centreville Road can help you select a wheel that has both the correct diameter and offset for your vehicle. Or, if you really want a specific wheel in spite of the offset difference, your technician may be able to install adapters that will make the wheels fit.

Mounting larger wheels is a more involved process. There are several ways of doing this. You can mount larger wheels but keep the overall tire diameter the same. Or you can “supersize” your tire/wheel combo. Mounting larger wheels while maintaining the same overall tire diameter is the easiest way to increase wheel size. You still need to adjust for offset. Generally, this alteration means that your new tires will be wider than the originals, so you will have to install adapters to keep them from rubbing on the wheel wells. Consult your service advisor at McLearen Shell by calling (703) 318-7744.

If you want to install larger wheels and increase the overall tire diameter, it is important that the package fits in the wheel well; you may have to do some minor modifications to your suspension. More importantly, you will have to reprogram your vehicle engine's computer to calibrate for the larger tire size. The computer calculates your speed based on the rotation of your tires, so increasing the size of the tires will render it inaccurate. Inaccurate speed calculations can mess up your anti-lock brakes and your stability control systems, as well as your speedometer and odometer.

As you can see, the more modifications you make, the more it becomes important to have your friendly and knowledgeable McLearen Shell tire and wheel professional help you with your car care.

If you really want those “super-sized” tires, great: just factor in the issues listed above, plus you may have to have modifications done to your suspension system.

The larger wheels and tires will add weight to your vehicle. This weight is not held up by the suspension system, so is referred to as “unsprung” weight. Adding unsprung weight affects your car differently than just adding loads inside of your car. Unsprung weight can affect acceleration and braking. Putting large wheels on your vehicle may require an upgraded brake system.

Also, you may not get the performance from your vehicle that you've been used to. It may be sluggish when accelerating or harder to handle when turning. You may also find that the ride is bumpier than it was before. Of course, done right at McLearen Shell, a good wheel job can sometimes improve a vehicle's ride or performance. It just depends on your vehicle, the type of wheels you choose and what you are hoping to accomplish.

Now let's suppose you want smaller wheels on your vehicle. That should be easier, right? Not really. You still have to worry about offset, and it is important that your computer be reprogrammed to account for calibration issues. And you may need adjustments to your suspension system.

Remember your budget? All of these scenarios require that you shell out some money. Perhaps now you can see why it is good auto advice for Herndon drivers to make that consideration first, before setting their heart on a specific type of wheel.

Another consideration should always be your driving habits. Do you do a lot of off-roading on the outskirts of Herndon? Do you carry heavy loads? Do you tow a trailer on VA roads? All of these factors must be considered when replacing your tires and wheels. Some wheels just may not be up to the work you need them to do.

For example, if you mount large rims on your vehicle, then add low-profile tires to avoid major adjustments to other systems, they won't be able to handle off-roading as well as larger tires. There won't be enough sidewall on the tires to absorb the impact from off-roading. You could end up with dented or broken rims.

At the end of the day, Herndon drivers should always put safety ahead of appearance. That's why you shouldn't add custom wheels to your vehicle without consulting with your McLearen Shell tire and wheel professional. Cutting corners when installing custom wheels by not making necessary adjustments to all of the systems impacted by the change can result in dangerous operating conditions as well as repairs down the road.

The friendly and knowledgeable auto professionals at McLearen Shell want to remind Herndon drivers of the basics of vehicle safety: preventive maintenance, emergency preparedness and professional repairs. Stay safe, and stay on the road.

When You Hear the Crash in Herndon: What to Do After an Accident

Motorists in North America drive about 3 trillion miles/4.8 trillion kilometers every year. There are over 250+ million licensed drivers, and approximately 6.2 million accidents happen every year. Unfortunately, if we're going to drive vehicles, there are going to be accidents. Knowing what to do in case of an accident can help reduce the stress and cost of the situation. It can also protect you from false claims, incorrect judgments and unjust liabilities.

Never leave the scene of an accident. This is a crime, even if the accident is not your fault. If you leave the scene, it is referred to as a “hit-and-run,” and the fines are steep in VA. You can even lose your driver's license or spend some time in jail. If someone has been injured in the accident, most laws require you to help them. You must call for help. If you can, you must also render first aid.

Call 9-1-1 or get someone else to call 9-1-1 as soon as possible. Tell the operator if there are injuries or any circumstances that require fire services, such as leaking gas, broken utility lines or, of course, flames. Put out flares, turn on your flashers or lift your hood to warn other Herndon motorists that there's been an accident.

File a police report. This can seem like a hassle when there are no injuries and only minor damage to vehicles. But you'd be surprised at the lawsuits and false claims that can arise from fender benders. You want a police report to protect yourself.

Don't talk about the accident with anyone except the police. After an accident, adrenaline is pumping and emotions are running high, and our first reaction is often to relive and recount our experience. Don't. Again, people can and will use your words against you, and in a highly emotional state, you may not say exactly what you mean. Entire court cases have hinged on the meaning of one misplaced word. Talk to the police. Don't admit guilt or fault, not to the police or to anyone else. People often feel guilt after an accident, but later, when details are analyzed, it turns out not to be their fault. Don't say, “I'm sorry,” but rather, “Can I help? What can I do?” Sympathy has often been misconstrued as an admission of fault. On paper, your words will sound more sterile than at the accident, and they can be used against you.

Collect contact information from everyone involved in the accident. Get the officer's name and badge number. Get the other driver's name, address, phone number, date of birth, driver's license number and expiration and insurance information. Get a description of the other vehicle as well as its license plate number and vehicle identification number (VIN). Most insurance companies don't keep records of license plate numbers, so the VIN is the best identifier you have of another vehicle.

This is going to be too much to remember once you're in an accident. So write down or make a note on your phone with the information you need.

Ask witnesses to wait for the police to arrive. If they can't, then get their contact information. Ask them to jot down what they saw. If witnesses refuse to give you their names, write down their license plate numbers. That way the police can find them if necessary.

After the accident, call your insurance company. Also, if you have or think you might have an injury that did not require immediate care at the accident, contact your physician right away.

There's a lot Herndon drivers can do to prevent accidents. Defensive driving. Good car care and preventive maintenance. But if an accident does happen in the Herndon area, we should be prepared to handle it well. It will ease the stress of the situation and protect us from potential legal and financial harm. Be prepared. It's good auto advice in every situation. Ask our pros at McLearen Shell for more safe driving tips the next time you visit.

Automotive Tips from McLearen Shell: Wiper Blades ? Signs of Wear

90% of our driving decisions are based on vision. Anything that impedes your vision can affect your driving safety – including a dirty windshield. In that sense, your wiper blades are an important safety system. Most Herndon drivers will wait until their wipers have failed before they replace them. Then they find themselves in a driving situation around VA when they really need forward visibility only to discover that their wipers are worn or maybe even torn and can’t clear snow or rain from the windshield.

As an important safety system, wiper blades should be replaced BEFORE they fail. Test your wipers at least once a month. If they are not doing the job, your friendly and professional McLearen Shell service advisor can replace them for you.

Give us a call.

On Board Diagnostics for Your Engine

Starting in 1996, McLearen Shell service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.

Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)

If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs immediate attention at McLearen Shell. When the Check Engine light is flashing, the vehicle should not be driven at high speeds, haul heavy loads or tow a trailer. Herndon drivers need to understand that doing so can cause major damage.

When a vehicle is brought to McLearen Shell in Herndon because the Check Engine light is on, a technician will scan the Engine Control Module to learn why it turned the light on. The answer comes as a “trouble code.” The technician has access to software that allows him to enter the code and find out what it means. The software will also let your McLearen Shell technician know what might be causing the problem and how to diagnose it.

Notice that the trouble code does not tell your technician at McLearen Shell exactly what is wrong with the vehicle. It can only let him know where to start looking to find the problem.

Scanning a trouble code and determining what it means is fairly simple for the pros at McLearen Shell. But the ensuing process of actually diagnosing a vehicle's trouble can take a skilled technician some time. Sometimes this can add up to a significant repair bill. Some vehicle owners mistakenly believe  that the “trouble code” is all they need and think they can then fix their vehicles themselves. Some have tried to save money by purchasing an inexpensive scanner, or they take their vehicles to an auto parts store that offers the scan for little or no cost.

These options are often not the money-savers they seem for Herndon vehicle owners. They can end up costing the vehicle owner extra in unnecessary repairs and engine damage.

For example, the trouble code P0133 reads “Bank 1 sensor 1 circuit slow response.” Translated, that means the front oxygen sensor shows a slow response time in changing the mix of air to fuel. The seemingly obvious conclusion is that the sensor needs to be replaced. The vehicle owner purchases a sensor, installs it and happily goes on his way.

However, read the trouble again: a slow response time in changing the mix of air to fuel. Nowhere does this indicate that the sensor is bad. There are a lot of parts involved in changing the air-fuel mix, any of which could be causing a slow reaction time. Those include a bad or contaminated airflow sensor, an exhaust leak, a problem in the electrical system or a leak in the intake manifold. The sensor is merely relaying that the response time is slow; it doesn't indicate where the trouble is.

So the vehicle ends up with an oxygen sensor it did not need, and the delay in repairing the actual problem may have led to further damage to the engine. Both are added costs for the vehicle owner.

Cheap scanners also don't have the ability to read the history stored in an engine's computer. This operating history contains clues that can help in diagnosing engine trouble since it can indicate a developing problem. McLearen Shell invests a lot of money in high-end diagnostic equipment so that we have access not just to service codes but also to the operating history of the engine.

On-board diagnostics, then, are a tool to help diagnose what is wrong with a vehicle. They cannot specify what part needs to be fixed or replaced, and they cannot replace a well-trained and well-equipped service technician.

Unless you are a trained mechanic, it's good auto advice to use McLearen Shell for your car care. In the long run, it can save you time, unnecessary expense and frustration. McLearen Shell can also help you keep up with your scheduled preventive maintenance, which can also save you on repair bills by alerting you to potential problems before they get expensive.

How Does McLearen Shell Know What to Recommend?

When you drop your vehicle off at McLearen Shell in Herndon, they don't just poke around under your hood looking for stuff to do. McLearen Shell professionals have lists and procedures they follow for different types of service. First of all, your Herndon service center will note the mileage on your vehicle. They'll then check to see what inspections and services the vehicle manufacturer recommends for a vehicle of your make, model and mileage. If you are a regular customer, they will also check your vehicle's history.

If the vehicle manufacturer's recommendations go beyond the services you've ordered, they'll let you know. They'll also indicate whether those services are urgent or if you can wait a while to take care of them. The McLearen Shell pros won't do work that you don't agree to.

They will, however, perform inspections while they're servicing your vehicle. They'll check belts, filters and fluids. They'll check your windshield wipers for wear. They'll let you know if there's an urgent problem that needs taken care of, and they'll give you a heads-up about problems that might be developing. If repairs or services are in order, you are given options based on driving needs and budget.

You can think of it like a trip to the dentist for a check-up. The dentist will check if you've had x-rays recently. If not, he'll get your permission to take new ones. Then the hygienist will clean your teeth and check your gums. At the end, the dentist comes in and inspects your teeth. You'll be told if you need any work done, about problems that are developing, and if anything is urgent. You'll be given different care options and recommendations on where to get work done that is beyond your dentist's usual purview. Then you'll be sent to the front desk for appointments and paperwork.

These procedures make sure your teeth are in good working order and that you are apprised of any problems. Then you can make a decision as to what work you want done and when. McLearen Shell in Herndon operates the same way. They want Herndon drivers to be able to make informed decisions about their car care.

Preventive auto maintenance is a lot like dental check-ups. Small problems can quickly develop into big ones. A cavity becomes a root canal. A dirty filter becomes engine damage. Skipping check-ups for either your teeth or your vehicle can lead to repairs.

McLearen Shell follows industry guidelines. A part is replaced only if it can no longer perform its function, no longer meets its design specifications or is missing – or if you ask for upgraded performance. Your McLearen Shell service advisor will recommend a part be replaced if it is showing signs that it will soon fail.

Dentists often offer services that go beyond routine care, such as teeth whitening. Service centers also offer Herndon drivers help with upgrades to a vehicle. They'll know what parts are needed and how to perform the work so that safety and performance aren't compromised. You can rely on the pros at McLearen Shell for good auto advice.

The next time you're headed to the dentist's office, think about the vehicle you're riding in. Is it time for it to get a check-up, too?
