Clean Air for Your Engine: Engine Air Filters In Garner

Every Garner 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 vehicle owner's manual will have a recommendation of when the filter should be replaced.

So between your owner's manual and your Garner technician's inspection there's really no guesswork involved for Garner drivers.

Now, most air filters purchased in Garner don't cost a lot to replace. It's just that NC people hate getting caught with an unexpected expense. On the plus side, though, changing a dirty air filter at Matt Davis Auto can often save enough on gas to pay for itself before your next oil change in Garner.

Think about a dirty furnace filter in your Garner home. When it's all clogged up, enough clean air can't get through. In your vehicle, 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 gas to move your vehicle around Garner roads.

Your vehicle actually needs about 12,000 times more air than fuel to run. Engine air filters don't cost much in Garner at Matt Davis Auto. When it's time to change yours, just get it done. You'll get better fuel economy, have better performance and protect your vehicle engine.

Conventional or Synthetic? (Switching to Synthetic Oil)

If you keep up on technology trends, then you may be intrigued about synthetic motor oil.  It was introduced in the 1960s when Mobil came up with it.  Mobil's oil was different from conventional motor oil because it was first broken down to its basic molecules.  Then, Mobil removed additional impurities from crude oil and "tailored them to the demands of modern engines."

Synthetic oil is becoming more popular now because of its advantages over conventional oil. It's more resistant to sludge forming in an engine.  It is more efficient and protects engines better under temperature extremes.  Because it allows drivers to go longer between oil changes, many feel it's more convenient. 

The downside is that synthetic oil is more expensive, but because it doesn't need changing as often, the cost can be pretty comparable in the long run.

Those who drive high performance vehicles (think Audi, BMW, Mercedes) are already using synthetic oil if they're following their manufacturer's guidelines.  Other manufacturers recommend a synthetic blend.  So for those who are using conventional oil, you may want to consult your service advisor for some recommendations if you want to switch to synthetic. 

If you're the type who always waits until the last-minute or doesn't ever get in quite in time for the recommended oil change interval, the longer gap required between changes with synthetic oil may appeal to you.  In some cases, you can go up to 15,000 miles/24,000 km between changes. 

If you drive in a very cold climate, synthetic oil can flow more easily at startup and may offer quicker engine protection.  On the other hand, in hot climates, synthetic oil can resist heat breakdown better.

Or you may be one of those drivers who have been getting along fine with conventional oil changes.  Millions do.  Just remember that changing your oil is considered the most important maintenance you can do on your vehicle, so make sure it's done at the right time and with the oil that best suits your driving needs.

Weather Station on Wheels (Vehicle Sensor Maintenance)

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station, and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems is important to make sure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.

Hitting the Brakes in Garner

Safety should always be an element of your vehicle care. So even if you don't care about how your vehicle looks, you should practice preventive maintenance to protect yourself — and other Garner drivers — on the road. And good safety starts with good brakes.

Brakes need a regular inspection. There are  parts that wear out or wear down, and it's best to replace them before you have serious problems.

Of course, if you are having trouble with your brakes, NOW is the time to fix them. If your brake warning light is on, that's a good sign that you need your brakes checked. You can also tell something is wrong with your brakes by the feel of the pedal or unusual sounds while braking. If the brake pedal is low, feels spongy when you press it or is hard to push, that indicates a problem with your brakes. If you hear squealing, grinding or clunking noises when you brake, that can also indicate serious problems. If vibrations accompany braking, then it is to get your brakes checked.

Brakes come in two basic types. With disc brakes, a rotor is attached to the axle of the vehicle. Padded calipers straddle the rotor and close when the brakes are applied. The resulting friction causes the rotor — and the axle — to stop turning. With drum brakes, brake pads (also called shoes) press against the inside of a drum to create friction and stop the drum, and hence the vehicle's wheels, from turning.

When Matt Davis Auto services your brake system, your friendly and knowledgeable service advisor checks all of the brake pads for wear. If they are too thin, they need to be replaced. This is an inexpensive repair at Matt Davis Auto compared to what procrastination will cost you. If pads wear away completely, then the rotors and drums can be damaged. They will have to be either resurfaced or replaced, and that can be expensive. But if your vehicle brake pads are worn out, then your brakes are compromised and your stopping power is greatly reduced. You could easily wind up in an accident.

Brake pads come in several different grades such as regular, metallic and ceramic. The higher grades are more expensive, but they also work better. NC drivers who want better and smoother braking should consider upgrading. However, Garner drivers should NEVER use a brake pad that is lower than their vehicle manufacturer's recommendation.

After your brake pads are checked at Matt Davis Auto, it's also wise to have your brake fluid checked. This is a critical element in your brake system. When you press your brake pedal, you are compressing the brake fluid, creating pressure that activates the brake pads. If your fluid pressure is low, it will decrease your braking power. The pads just won't be able to press hard enough against the rotor or drum to stop your vehicle. Just as with worn pads, insufficient brake fluid can lead to an accident in Garner.

Water can build up in your brake fluid, which can cause corrosion in your braking system. Eventually this can cause your brake fluid to leak. So Garner drivers should also change their brake fluid periodically. Your vehicle owner's manual will have guidelines on how often it should be replaced, or you can ask a service advisor at Matt Davis Auto. 

Remember, Garner folks, safety first. It's auto advice for all Garner drivers on the road. You're not just protecting others; you're protecting yourself.
