Check Your Engine


Check your belts
At the front of your engine there will be a series of rubber drive belts that loop around various pulleys, driving everything from the alternator to the a/c compressor. Rubber perishes, more so in extreme conditions like those found in an operating engine bay. Get your timing belt and accessory drive belt checked every 25,000 miles, preferably replacing it every 50,000 miles. See the Fuel and Engine part of your owner's manual for information on interference engines and why checking your timing belts is a necessity, not a luxury.
Fuel Economy
Check your tire pressures regularly - once a week is ideal. Bad tire pressures can affect fuel economy very noticeably. It's easy to do and there is no excuse not to.
