First and foremost, you should keep tabs on the vital signs of your car. Check the oil regularly and make sure the temperature does not exceed the half- way mark. These two areas are the primary causes of pre-mature engine failure. An engine in its prime can still become junk if its allowed to run out of oil or water. Don't be alarmed by a slightly above average use of motor oil. Rotary engines inject a small amount of oil for lubrication. Every once in a while, top off your oil and zero the trip odometer. See how many miles you go before you need another quart. A new engine uses a quart in 1600-1800 miles, but you shouldn't begin to worry until it gets to about one quart per 700 miles.

Change your oil and filter regularly. This cannot be emphasized enough. Changing your oil and filter about every 3000 miles is probably the best thing you can do to extend the life and performance of your engine. Make sure you use an oil and filter of good quality.

If you had a new or rebuilt engine installed, observe the "break-in" rules. Negligence will be costly since the warranty will be voided and the engine may sustain irreparable damage in extreme cases. Be easy on the motor for the first 500 miles. This means, a) no heavy load hauling, b) do not exceed 4000rpm, c) do not exceed 70 mph in top gear, and d) do not drag race. After putting 500 miles on the motor, change the oil and filter, retension the belts, check all hoses, and look carefully for any oil and fuel leaks..

Another helpful idea is to have a regular maintenance schedule. Regular maintenance can identify problems before they become serious ones. Tune-ups, oil changes, brake work, and other maintenance done at the proper time will save money in the end. Have all these things done by a competent shop that knows your car. Remember, an ounce of prevention beats a pound of cure.

Be proud of your car. It's not just transportation, it's an extension of yourself. Your character is reflected in the way you treat it. Keep it clean inside and out. Wash and wax it occasionally and vacuum the carpet. Doing all these things may not extend the life of the engine much, but it sure keeps the value of your investment and makes the car more fun to drive.
