Tire Maintenance In SachseMarch 6, 2013

With the recent focus in Sachse on improving fuel economy, we’ve been told how important it is to maintain our tire pressure.

Everyone in Sachse knows that tires wear out, but we all want to make them last as long as possible because they’re fairly expensive to replace. In addition to saving gas, properly inflated tires last longer. Under-inflated tires will wear out more quickly.

Some people in Sachse wonder if there is benefit to adding a few extra pounds of pressure when they fill up their tires. But actually, there isn’t. In fact, there are very good reasons not to over-inflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling.

Every vehicle in the Sachse area has a sticker on the driver’s side door jamb that tells you the manufacturer’s recommended tire pressure. This recommendation is an integral part of the vehicle’s suspension tuning. A lot of engineering actually goes into the recommended tire pressure, so it’s important to follow it.

What else do we need to know about tire maintenance? Tire rotation and balancing are very important. Let’s start with rotation. Because the front tires handle the brunt of turning forces, the shoulders of the front tires wear more quickly than the rear tires. We rotate the tires so that they all get to do some duty on the front and they’ll all wear evenly over their life.

For most vehicles, front tires are rotated to the rear and vice versa. Others recommend a cross rotational pattern. Some vehicles use an asymmetrical tire so those tires need to stay on either the right or left side – it’ll say which on the tire. Some high performance cars have asymmetrical tires and different sizes on the front and rear. These can’t be rotated at all. Your owner’s manual will have details for your car.

How often should you rotate your tires? Your owner’s manual will have a recommendation. Your service advisor at Lewis Complete Auto Repair can do a visual inspection to let you know if it looks like it should be done. The interval is typically around 5,000 miles.

You know, some people don’t think new tires need to be balanced. What they aren’t taking into account is the wheel. Between the wheel and the tire – even a new tire – there’s enough variation to require balancing.

When you add the valve stem and tire pressure monitoring sensors required on new cars, balancing is definitely in order. When a tire’s out of balance, it’s actually hopping down the road. You’ll feel the vibration through the steering wheel if a front tire’s out of balance and through your seat if it’s a rear tire.

Proper wheel balance promotes tire life and increases safety. Historically, lead weights have been attached to the wheel to bring it into balance. Lead gives some environmental concern, so steel weights are starting to be substituted.

Also, always use the same size tire on an axle. Different size tires on the front or on the back can lead to some real handling problems. And tire manufacturers recommend that when you get two new tires, they be installed on the rear because that’s where you need the most traction to avoid spinning-out.

How to Know When to Change Your Oil At Lewis Complete Auto RepairFebruary 27, 2013

Today in the Lewis Complete Auto Repair auto care blog, we’re going to talk about oil change intervals. It seems that as engine technology advances, recommended oil change intervals have gotten longer for Lewis Complete Auto Repair customers. High quality oil in a well-engineered truck engine has lead to extended intervals. But it’s also lead to some confusion among Rowlett motorists.

The old mantra “change your oil every three months or three thousand miles, whichever comes first” once applied to every vehicle on Rowlett expressways. Time and miles take their toll on motor oil. But now, you could have a different oil change recommendation for every car or truck you own.

Rowlett motorists are like everybody else, they have a tendency to follow the oil change schedule of the vehicle with the longest interval. Of course, that can lead to problems. How to Know When to Change Your Oil At Lewis Complete Auto RepairFor example, recently four of the world’s largest auto makers shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles.

In real world Rowlett 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 truck 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 Lewis Complete Auto Repair in Rowlett.

The auto makers 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: with longer oil change intervals, it’s essential to follow them closely. Back in the day of 3 months or 3,000 miles, if you went an extra month or an extra thousand miles, 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 and you go over another thousand, 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 TX, short trips, drive in dusty or polluted Rowlett conditions, hot or cold weather, or haul heavy loads, you’re driving in severe service conditions. Your Lewis Complete Auto Repair advisor can help you determine which schedule to follow.

So check your truck owner’s manual or talk with your Lewis Complete Auto Repair service advisor about where and how you drive in Rowlett. 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 trucks 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 to almost 7,000 miles. It’s typically just over 4,000 miles. Clearer sometimes, we’re driving easy miles that are easy on the truck – like a long road trip. Sometimes, we’re driving hard TX miles – 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 Lewis Complete Auto Repair to protect your truck engine. Another place where TX motorists can go wrong is with the type of oil they use. More and more new cars are coming to Rowlett 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 Rowlett people are tempted to use conventional oil for their oil changes. Now, it’s always best to use the oil recommended by your manufacturer. Check your owner’s manual see if a conventional oil alternative is allowed.

But getting back to the problem, if your truck 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.

TX Balance: Wheel Balancing and Tire RotationFebruary 21, 2013

Everyone in the Rowlett area wants our tires to last as long as possible. Two ways to maximize tire life are wheel balancing and tire rotation.

When wheels are out of balance, they wobble a bit. That makes the tires wear in a cupping pattern. And they vibrate. To fix this, your service technician at Lewis Complete Auto Repair puts weights on your wheels to balance them out. If a front wheel is out of balance you’ll feel it in the steering wheel. If it’s a rear wheel you’ll feel it through your seat.

That brings us to tire rotation. The front tires on a car wear out more quickly than the rear tires. As they push through turns from Rowlett to Sachse, the shoulders of the front tires wear down. So rotating front and rear tires allows them to all wear at about the same rate over the life of the tire.

Proper tire inflation will also help your tires last longer. Under-inflated tires wear excessively on the shoulder and may even overheat. This could cause tire damage or a blow out. Over-inflated tires wear to fast in the middle.

Four wheel drive trucks and SUV’s tend to wear their tires more unevenly so rotation is even more important with them. Give us a call to get our recommendation on your truck.

See your owner’s manual or ask your service technician at Lewis Complete Auto Repair for your recommended tire rotation schedule. It’s usually every 5,000 to 8,000 miles.

Tires cost a lot and they are one of the most critical safety components on your vehicle. Take care of them and they’ll take care of you.

Clean Air for Your Engine: Engine Air Filters In RowlettFebruary 12, 2013

Every Rowlett car owner who has taken their car in for an oil change has been told that their engine air filter’s dirty.

Here’s what goes into the determination of when to change the filter: First, your truck owner’s manual will have a recommendation of when to change the filter. Second, a visual inspection by your Rowlett technician may determine that your filter it is visibly dirty and needs to be changed.

Clean Air for Your Engine Rowlett Engine Air Filter

So between your owner’s manual and your Rowlett technician’s inspection there’s really no guesswork involved.

Now, most air filters purchased in Rockwall, Garland, or Sachse don’t cost a lot to replace. It’s just that TX people hate getting caught with an unexpected expense. On the plus side, though, changing a dirty air filter at Lewis Complete Auto Repair can often save enough on gas to pay for itself before your next oil change in Rowlett.

Think about a dirty furnace filter in your Garland home. When it’s all clogged up, enough clean air can’t get through. In your truck, that means that your engine can’t get as much air as it needs to burn the fuel efficiently. So it makes do with less air and has to use more expensive TX gas to move your vehicle around Rowlett roads.

Your truck actually needs about 12,000 gallons of air for every gallon of gas it burns. Engine air filters don’t cost much in Rowlett at Lewis Complete Auto Repair. When it’s time to change yours, just get it done. You’ll buy less fuel, have better performance and protect your engine.

Rowlett Customer Detective WorkFebruary 7, 2013

One might say the most challenging part of being an automotive service technician at Lewis Complete Auto Repair in Rowlett TX is diagnosing a problem before it can be fixed.

Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So it’s challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it’s not something obvious, it’s easy for the customer to focus on the fixing and not the diagnosing.

Let us introduce you to something we’ll call Customer Detective Work – that is helping your Rowlett TX technician find clues to what’s wrong.

We start with the detective basics: What, Where and When. Play along with me. You come in to Lewis Complete Auto Repair and your car is making a funny sound.

  • Q: Where’s the sound?
  • A: Around the right front wheel.
  • Q: What kind of sound?
  • A: Kind of a clunk, clunk sound.
  • Q: When do you hear the sound?
  • A: When I turn and accelerate.
  • Q: Right and left? Forwards and back?…

Do you see where we’re going? You’re gathering additional information to help your Rowlett TX technician know where to start. Based on your car and the tech’s experience, he’ll know where to look and can start with the obvious suspects.

You can see how that would be more helpful than dropping the car off with a note that says “making a funny noise”.

When you think you need to bring a vehicle in, make some notes about the problem. Rather than just saying “it’s leaking”, tell the tech the color of the fluid, and approximately where under the car you see the puddle.

Things like ‘the car is stalling or sputtering’ are often very hard to diagnose because they’re intermittent. They may not happen every time you drive and usually aren’t happening when you actually bring the car in. So, it is a big help for you to describe what’s happening in as much detail as possible.

Your Rowlett TX technician at Lewis Complete Auto Repair will need to be able to duplicate the problem if possible so he needs to know details, like ‘it stalls after it’s been driven for about 20 minutes and I go over 50 miles an hour’.

If the tech can experience the problem personally, he’s better able to make a diagnosis and repair. And, then test to see if the repair solved the problem.
