- Make sure your technician checks your A/C system for proper freon level and condition of belts. To help conserve gasoline, use your air conditioner on the road rather than keeping windows down. Open windows create wind drag, straining the engine.

- Change engine oil and filters if you haven't done that in the last three months or 3,000 miles.

- Check the condition of the windshield wiper blades and have them changed if they do not provide adequate visibility, and top off the windshield wiper solution (do not use plain water).

- Use cruise control to maintain a steady speed and save gas.

- Use only the fuel octane recommended for your car. Higher octane gas, which produces less energy, not only costs more, it also yields lower miles per gallon.

- Every time you stop for gas, check oil level and inspect tires, and clean the windshield. Do NOT check coolant level when engine is hot, except to visually inspect the overflow (or recovery) bottle. If you are just making a quick pit stop (five minutes or less), do not cut the engine; let the car idle for a few minutes.

For added peace of mind, Joel Burrows, a.k.a. "The Car Doctor" and veteran trainer at Precision Tune Auto Care, suggests an engine and emissions analysis to ensure there are no problems and that the engine is running at maximum efficiency. This, too, helps reduce your fuel bill. And for safety he recommends you bring a cell and road map.
