Today's family automobile is a sophisticated, computer-controlled machine that requires less care and is more dependable than its predecessors. But to keep your car running efficiently, regularly scheduled maintenance is key to reliable performance and can mean savings down the road. Without regular maintenance, you can shorten the life of your vehicle and void its warranty.

NAPA AutoCare Centers recommend a five-point preventive maintenance program to keep your car running smoothly:

• Oil Change — Unless your driving is mostly highway miles, today's engines will run better and last longer with clean oil every 3,000 miles or three months, including a filter change. A $30 oil change can save you from costly engine repairs later.

• Brakes — An unusual noise or a gentle tug on the steering wheel when stopping are common warning signs that it's time to check the brakes. A good rule of thumb is to check the brakes at the 6,000- to 7,500-mile mark when tires should be rotated.

• Coolant System — Thoroughly flush coolant systems and replace with the appropriate antifreeze at least every two years to minimize metal deterioration and to keep the system flowing. And be sure to use the correct water to coolant mix. Check the coolant reservoir monthly (and the windshield washer reservoir, too) and top off as needed.

• Battery — As part of your car's regular maintenance, ask your technician to make sure the battery cover is in place and the battery is firmly anchored. Most important, clean the battery of corrosion, especially the electrical posts.

• Check-Engine Light — An illuminated check-engine light on your dashboard is your car's early warning system that something is wrong. It could be as simple as a loose gas cap or spark plug wire, or a serious forewarning of a mechanical failure. Take your car to an ASE-certified technician as soon as possible to diagnose and fix the problem.
