Keeping Your Car in Shape – It Adds to the Bottom Line

In this day and time when every dollar counts, there are three things you can do to keep you car in shape and add to the bottom line.

1) Keep your engine properly tuned.

If your car is noticeably out of tune or has failed and emissions test, fixing those two things can improve gas mileage by an average of 4 percent.   Correcting a serious maintenance problem, like a faulty oxygen sensor, can improve mileage as much as 40 percent.

2) Keep tires properly inflated.

Improve gas mileage by about 3.3 percent by keeping tires inflated to the proper pressure.  Under-inflated tires can lower gas mileage by 0.3 percent for every 1 psi drop in pressure of all four tires.  Properly inflated tires are safer and last longer.

The proper tire pressure for your vehicle is usually found on a sticker in the driver’s side door jamb or the glove box and in your owner’s manual. Do not use the maximum pressure printed on the tire’s sidewall.

3) Use the recommended grade of motor oil.

You can improve your gas mileage by 1-2 percent by using the manufacturer’s recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1-2 percent.

Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1-1.5 percent. Also, look for motor oil that says “Energy Conserving” on the API performance symbol to be sure it contains friction-reducing additives.

Yes, it may take a bit of effort and a tad of money up front, but in the long run, keeping your car in shape adds to the bottom line.
