For Brakes' Sake (Brake Rotor Service in Herndon)

Think of how much abuse your brakes take. Day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be.

Then it's time to get your brakes checked out. After all, you have to be able to stop if you want to be safe. Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime.

Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate.

It used to be that rotors were thick, and when they warped, a technician could "turn" them to scrape off a layer of metal so their sides were straight again. The latest vehicles are using thinner, lighter rotors with a slightly different construction. Now, it's likely that rotors that are resurfaced this way will not have enough metal left to work safely. In fact, some manufacturers advise only replacing rotors that are worn out.

Newer designs have reduced rotor prices, and in many cases, the labor cost of turning the rotors is higher than buying new. There are times, though, where your rotors can be resurfaced and still meet manufacturer specifications.

If you have a rotor replaced on one side of your vehicle, it might be a good idea to replace rotors on the other side, too.

Maybe you're looking for the new rotors to last longer than the ones that were on there. New technologies can offer a longer lifespan in a premium rotor. Armed with knowing the type of driving you do, you and your McLearen Shell service advisor can make the best decision on which direction you want to go with your new brakes.

Drive Defensively in VA

Car care is part of auto safety in Herndon. But the most important thing we can do to improve safety on VA roads is to drive safely.

Defensive driving begins with the proper attitude. Have in mind that you won't let anyone take your safety away from you. You'll be aware of your surroundings, road conditions, other vehicles and hazards. And the first person to be concerned with is you: start with your own environment.

Don't leave without securing all occupants including children and pets. Watch for loose items that can become projectiles during evasive maneuvers.

Driving too fast or too slow increases the chance of an accident.

Never drive impaired: Alcohol is a factor in half of all fatal crashes. Never drink and drive.

Other impairments include being sleepy, angry, daydreaming or talking. If you suddenly wonder how you got where you are – you're not paying enough attention.

Keep your windows clean and uncluttered. No fuzzy dice and stickers.

Keep your car in good shape so that it handles properly: Maintain tires, lights, brakes, suspension, wheel alignment and steering.

Always use your turn signals while driving around Herndon, VA. Avoid other vehicles' blind spots.

Don't drive faster than your headlights – if you can't stop within the distance you can see, you're going too fast.

Avoid driving over debris in the road. Even harmless looking items can cause damage or an accident.

Keep your wheels straight when waiting to turn at an intersection in Herndon . That way if you're hit from behind, your car won't be pushed into on-coming traffic.

My daddy always said that when you drive, you're actually driving five cars: yours, the one in front, the one behind and the ones on either side. You can't trust that other drivers will do the right thing, so you've got to be aware of what they're doing at all times.

If you see another car driving erratically, weaving, crossing lanes, etc., stay back. Take the next right turn if you're downtown Herndon, or take the next exit on the VA highway. Notify the police if you see someone driving dangerously in our Herndon community.

Never follow too closely. The minimum distance is the two second rule. Pick a landmark ahead, like a tree or road marker. When the car in front of you passes it, start counting: 'one-one-thousand, two-one-thousand.' If you pass the landmark before reaching two-one-thousand, you're following too closely.

Remember that the two second rule is the minimum – it assumes you're alert and aware. Three seconds is safer. Move out to five seconds or more if it's foggy or rainy.

Someone will inevitably move into your forward safety zone – just drop back and keep a safe distance.

If someone follows you too closely, just move over.

Don't play chicken by contesting your right of way or race to beat someone to a merge. Whoever loses that contest has the potential to lose big and you don't want any part of that. So stay alert, constantly scan around your car and arrive safely.

Tire Rotation and Balancing at McLearen Shell in Herndon

Tires do a lot of work for Herndon drivers. They transfer engine power and braking forces to the road; they handle steering control; and they cushion all those bumps and jolts while driving around Herndon. They also support the entire weight of the vehicle, including you and your passengers. With such important work to do, you want your tires to do their job well. And since replacing tires is fairly pricey, you want them to last as long as possible.

There are three keys to long, even tire wear for Herndon driving:

• Proper tire inflation
• Proper wheel alignment
• Regular tire rotation and balancing

The front tires on a car take the brunt of the steering forces. As they push through turns, the shoulders of the front tires wear down more quickly than the rear tires. Rotating front and rear tires allows them to all wear at about the same rate. That's especially true of front-wheel-drive vehicles whose front tires steer and put the power to the road.

SUVs and pick-ups, especially four-wheel-drives, also tend to wear their tires more unevenly than cars because of their suspension and drivetrain set-up. Your owner's manual will likely contain a schedule for tire rotation. It's usually every 5,000 miles/8,000 km or so.

Also, there are different rotation patterns for different vehicles. McLearen Shell will know which is right for your vehicle. That brings us to wheel balancing. When wheels are balanced, they spin on the axle evenly. When they are out of balance, they wobble a bit. That makes the tires wear unevenly and may transmit a vibration to the car. Your friendly and knowledgeable McLearen Shell service advisor puts weights on your wheels to balance them out so that they turn true and smooth.

Tires are a big investment for Herndon drivers. They're designed for keeping you safely on the road in Herndon. The cost for regular rotation and balancing is more than made up in extended tire life. And, can you really put a price on your safety and that of your passengers?

How to Know When to Change Your Oil at McLearen Shell

Today in the McLearen Shell auto care blog, we're going to talk to Herndon drivers about oil change intervals. It seems that as engine technology advances, oil change intervals become longer for McLearen Shell customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).

In real world Herndon driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at McLearen Shell in Herndon.

The vehicle manufacturers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner had to follow a new, lower service interval and provide proof of oil changes in order to make a warranty claim.

So here's the bottom line for Herndon vehicle owners: with longer oil change intervals, it's essential to follow them closely. Back in the day of 3 months or 3,000 miles (5,000 kilometers), if you went an extra month or an extra thousand miles or couple of thousand kilometers, your oil was still fresh enough that it didn't have time to build up much sludge.

But if your recommended interval is 6,500 miles (10,000 kilometers) and you go over another thousand miles or couple of thousands of kilometers, you're getting into heavy sludge territory. You absolutely need to follow mileage intervals very closely. And don't forget your severe service schedule. If you do a lot of stop and go driving in VA, short trips, drive in dusty or polluted Herndon conditions, hot or cold weather  or haul heavy loads, you're driving in severe service conditions. Your McLearen Shell service advisor can help you determine which schedule to follow.

So check your vehicle owner's manual or talk with your McLearen Shell service advisor about where and how you drive in Herndon. Should you change your oil closer to the regular schedule, or the severe service schedule? You need to make the call.

Let me give you an example of this. Some newer vehicles have an oil change indicator. It has a sophisticated computer algorithm that tracks number of cold starts, engine temperature, RPMs, mileage and many more variables to come up with a recommendation for when to change the oil.

Depending on driving conditions, the indicator in one test vehicle came on at anywhere from 2,500 miles (4,000 km) to almost 7,000 miles (11,000 km). It's typically just over 4,000 miles (6,500 km). Sometimes our driving is easy on the vehicle – like a long road trip. Sometimes, our driving is hard on it – like towing a heavy trailer or a lot of around town driving. But, usually, it's a combination of both.

Once again, it's up to you to make the call as to when to change your oil at McLearen Shell to protect your vehicle engine. Another place where VA drivers can go wrong is with the type of oil they use. More and more new cars are coming to Herndon owners filled with synthetic oil. Without going into a lot of detail right now, let's just say that synthetic oil lasts longer and is very resistant to oil sludge.

But it also costs quite a bit more, so some people are tempted to use conventional oil for their oil changes. Now, it's always best to use the oil recommended by your vehicle manufacturer. Check your owner's manual see if a conventional oil alternative is allowed.

But getting back to the problem, if your vehicle came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil. If you use conventional oil, you can't use the synthetic interval. You need to shorten it.

Air Conditioning Maintenance at McLearen Shell in Herndon

Warm weather or cold, Herndon drivers still need to think about their vehicle's air conditioning. Most Herndon people don't service their air conditioning until after it fails. At McLearen Shell, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on.

Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at McLearen Shell in Herndon.

The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all Herndon vehicle owners know that air conditioning repairs can be costly. At McLearen Shell, we recommended that the air conditioner be run regularly, even during winter months, to keep the parts and seals lubricated.

Herndon drivers need to be aware that there's one more thing that isn't directly related to air conditioning service but does impact the quality of the air in your vehicle. And that's your cabin air filter. This filter cleans dust, pollen, pollution and other impurities in the air that come from the heater and air conditioner. The cabin air filter needs to be replaced when it's dirty. If you don't, it'll start to smell. Not all vehicles have one, so ask your McLearen Shell service advisor to check your cabin air filter at the same time they're doing your air conditioning service.
