The Truth About Batteries

Have you ever noticed when shopping for a car battery that there are two or three seemingly identical batteries on the shelf appropriately rated for your car, but the prices vary considerably? Why should one battery cost $20 more than the battery next to it?

Good Works Auto Repair explains in this video that lower-quality batteries tend to "sweat" battery acid, which corrodes the surfaces surrounding the battery. We share actual footage of corrosion completely destroying a car's $450 battery cable. In some cases, automotive battery cables can cost as much as $700 - certainly not worth the $20 savings on a low-quality battery!

What are Auto Diagnostics?

Technician

Long gone are the days when looking under the hood, checking the timing, and cleaning the spark plugs was all you had to do to figure out the problem and get your car to run right. Today's cars have sensitive sensors and computers that require sophisticated equipment to diagnose the problem and in some cases keep your car running in top condition. In fact, your vehicles' Check Engine light typically alerts you that there may be a problem with your vehicle.

Diagnostic codes are helpful tools to use, but it is important not to rely on them 100%. Trouble codes don't give you 100% of the answer -- they just point our technician in the right direction. "Test, don't guess" is our motto.

How can I get the best Gas Mileage?

The Car Care Council offers these fuel-saving tips:

Vehicle gas caps -- About 17 percent of the vehicles on the roads have gas caps that are either damaged, loose or are missing altogether, causing 147 million gallons of gas to vaporize every year.

Under inflated tires -- When tires aren't inflated properly it's like driving with the parking brake on and can cost a mile or two per gallon.

Worn spark plugs -- A vehicle can have either four, six, or eight spark plugs, which fire as many as 3 million times every 1,000 miles, resulting in a lot of heat and electrical and chemical erosion. A dirty spark plug causes misfiring, which wastes fuel. Spark plugs need to be replaced as recommended by the manufacturer.

Dirty air filters -- An air filter that is clogged with dirt, dust and bugs chokes off the air and creates a "rich" mixture -- too much gas being burned for the amount of air, which wastes gas and causes the engine to lose power. Replacing a clogged air filter can improve gas mileage by as much as 10 percent, saving about 20 cents a gallon.

Fuel-saving driving tips include:

Don't be an aggressive driver -- Aggressive driving can lower gas mileage by as much as 33 percent on the highway and 5 percent on city streets, which results in 10 to 66 cents per gallon.

Avoid excessive idling -- Sitting idle gets zero miles per gallon. Letting the vehicle warm up for one to two minutes is sufficient.

What should I do to get ready for a road trip?

From the National Car Care Council:

Tow truck operators in resort areas or along interstate highways see all too many travelers forced to return home ahead of schedule. Car trouble, usually due to neglected preventative maintenance, brings an abrupt end to vacation plans.

The situation usually means more than just a repair bill. It can involve towing charges, lodging and possibly a rental car. Add to that the cost of extra phone calls, meals and general inconvenience, and the ordeal becomes expensive.

Car in shop

This scenario usually can be avoided with a pre-vacation inspection performed by a qualified automotive technician. Goodworks Auto Repair recommends the following pre-trip "physical" for your automobile should address the following systems:

  • Cooling
  • Braking
  • Steering/suspension and tires
  • Battery and charging system
  • Fluids, belts and hoses
  • Windshield wipers and horns/lights/mirrors

Not only can a pre-trip inspection help reduce the chances of costly and possibly dangerous road trouble, it also provides an opportunity to have repairs made at home, with one's own technician who knows the vehicle. Especially important, it provides peace of mind. While no inspection can guarantee a car's performance, it's comforting to know proper precautions were taken.

What is a Tune-Up?

The term "tune-up" dates to the time when Henry Ford was working on his first automobile prototype. In Ford's simple ignition system, there was one ignition coil for each spark plug. If there were four spark plugs, there were four ignition coils, which needed to be adjusted to provide the same spark intensity for better idle and acceleration. As these ignition coils worked, they made a buzzing sound, and when they were adjusted properly, they all buzzed in "tune." The term "tune-up" stuck and became associated with replacing spark plugs and correcting rough idle problems affecting engine performance.

Once the distributor was developed, the term "tune-up" had no meaning, but the consumer who was used to hearing this term around a garage still associated poor running quality with the need for a "tune-up."

Today's automobiles do not require "tune-ups." The term indicates the need for routine maintenance and should not be associated with poor performance. Automobile manufacturers have developed recommended routine maintenance schedules, which specify intervals for replacing spark plugs, PCV valves, fuel filters, etc. These schedules also specify intervals for checking or adjusting ignition timing, idle speed and other items related to engine operations, as well as emission control related devices.
