3. Have a certified technician perform an engine and emissions analysis to ensure that the engine is running at maximum efficiency.

4. Avoid making quick starts or stops. To avoid jamming on brakes, stay a safe distance from the car in front of you. When possible, slow down simply by taking your foot off the gas.

5. Maintain steady speeds; use cruise control on the open road.

6. With today's high fuel prices an air induction and fuel injection cleaning restores power and performance and will squeeze every precious mile out of each gallon of gas.

7. Use proper octane fuel. Higher-octane gas, which produces less energy, not only costs more, it also yields lower miles per gallon.

8. Don't let the engine idle more than a minute or two. This is extremely important on cold morning start-ups.

9. Today's vehicles run on a fine film of fluids. Make sure you service all fluids on a regular basis and in accordance with the manufacturer's recommendations. Engine oil level should be checked at every fill-up.

10. Use over-drive gear for highway driving.

For added peace of mind, The Car Doctor 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 bringing a cell phone and road map.
