Spark Plugs – How Often Should They Be Replaced?

April 27th, 2017

In the old days, a tune-up was necessary about every 35,000 miles. It would usually consist of setting the ignition timing, replacing the mechanical breaker points in the ignition, cleaning and adjusting the carburetor and replacing the plug wires and spark plugs. Today, of course, the carburetor’s job is done by fuel injection and the ignition timing and spark are controlled by the engine computer. Few vehicles still have plug wires anymore either, as the distributor was replaced by the computer and a coil-on-plug design which delivers a spark at each spark plug.

But what about the spark plugs themselves, though? How often do they need to be replaced now?

Manufacturers tout an 80k-100k mile service interval on spark plugs now, thanks in part to improvements in plug design and materials. That might be stretching it, however. Remember that if you have a 100,000-mile spark plug, its electrode is worn down 4/5 of the way at 80,000 miles. A worn ...[more]

Regular, Synthetic or Blend...What Kind of Oil Do I Need?

May 26th, 2016

At one time, there were only a couple of choices for motor oil. Today, that is no longer the case, and hasn't been for quite some time. Here's a quick breakdown of what you need to consider when it's time for an oil change:

  • Viscosity: Viscosity is how thick your oil is, and how it retains its pour properties at various temperatures. In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. Check your owner's manual -- many newer models require a thinner, lower-viscosity oil, which also helps the engine run more efficiently. Viscosity is expressed as a numerical value -- the lower the number, the thinner the oil. Many are designed to work a ...[more]

Questions You Shouldn’t Be Afraid to Ask Your Auto Repair Tech

March 17th, 2016

Often, drivers are mystified by how their cars actually work. It’s to be expected. Even an older car is a complex machine with many sub-assemblies that all work together to move it down the road.Car questions? Ask them!

As a result, drivers tend to be a little intimidated by auto repair and often tend to not inform themselves by asking the necessary questions of a tech or a garage. Too often, that ends up being a big mistake. Here are some examples of the kinds of things you really should know before any auto repair work starts:

  • Does your shop work on any kind of vehicle? Of course, most shops can service a product from GM, Ford, Chrysler, Nissan, Toyota and the other leading makes. Some makes, however, require a lot more training and experience, o ...[more]

Winter is Coming

October 15th, 2015
The days are getting shorter, there’s a snap in the air, and before you know it, the winter months are going to be upon us. Is your vehicle ready? 
 
Wipers: Even the best windshield wipers are only good for about a year; normal wear, the sun’s UV rays and the elements take their toll on them. Get a good look and check them for chunks, strips or chips missing, and replace if necessary for a streak-free field of vision in wet weather. Hint: a fresh application of 
Rain-X on your windshield and window glass can help visibility greatly. 
Brakes: Are you hearing any squeaks, squeals or ...[more]

Six Hot Tips on Cool Air Conditioning

June 24th, 2015

Summer is here, and it’s time to start thinking about your car’s AC system! Nobody likes driving around in a hot, stuffy car, and a car with an AC system which only works marginally is somehow almost even worse than one which doesn’t work at all. Let’s go through a few tips which can help you keep your ride a little more comfortable this summer…

Remember a cars AC system is really a heat exchanger which moves hot air out of your vehicle, then replaces it with cold air. One thing you can do to help improve its efficiency is to leave your windows down an inch or two (if possible) when you park the car, helping to prevent excess heat buildup. When you start the car and begin to drive off, lower all the windows for the first minute or two to help move hot air out of the car more quickly, giving the AC system a chanc ...[more]

Get Ready for Summer Road Trips with New Tires

May 28th, 2015

Summer’s going to be here before you know it, and that means time for family road trips! 
 
We know there’s a lot to think about when you’re planning a vacation...money, accommodations, scheduling, keeping the kids occupied in the car...but one thing you definitely should not neglect in those plans is your tires. 
 
Summer road trips are hard on tires. You have to figure you’re in a car that’s likely loaded to the gills, driving for hours and hours to get to your destination in 90-plus-degree weather. That’s a good way to end up with overheated tires, and heat is the enemy of even the best tires. Here are a few things to consider before you load up the car and get going:

April: National Car Care Month

April 21st, 2014
April is National Car Care Month and there is no better time to break free from the chains of winter to start your journey to a dependable, road ready vehicle. Routine maintenance can seem overwhelming and with a never ending cycle of checks and replacements, sometimes it is hard to remember where one project ends and the next one begins. Knowledge is power and whether you are a mechanic or soccer mom every vehicle owner should have at least passing knowledge about their vehicle.
 
Allowing your vehicle to fall into disrepair during the winter months is nearly inevitable. Spending time working on a vehicle during an icy day is less likely than waking a hibernating bear and nearly as pleasant. Thus, when April is sprung upon us there is no better reason to go outside and enjoy the be ...[more]

What Does Your Check Engine Light Mean? - David's Commercial Tire

December 27th, 2013

Check Engine LightWhen your car's "Check Engine" light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. But in many cases, it means at minimum that you'll be visiting your mechanic to locate the malfunction and get the light turned off.

The Check Engine light, more formally known as the Malfunction Indicator Lamp (MIL), is a signal from the car's engine computer that something is wrong. Older vehicles may not have this, but any newer vehicle is equipped with a tiny all-knowing computer that will be your lifeline in communicating any problem with how the engine is running. Your Tire and Automotive service department can diagn ...[more]
