You can greatly improve your mileage by having your car serviced regularly and by driving wisely. Any of these eight points can help improve your mileage:
- Go easy on the brakes and gas pedal. Avoid "jackrabbit" starts by accelerating gradually whenever possible. Also, anticipate stops to avoid sudden braking.
- Avoid long idles. Turn off the engine if you anticipate a lengthy wait. Instead of idling at a drive-up window, park the car and go in. Idling burns more gas than restarting the engine.
- Limit car warmups in winter. Avoid carrying unneeded items in the trunk. Extra weight decreases gas mileage. Also, reduce drag by placing items inside the car or trunk rather than on roof racks.
- Avoid high speeds. You can improve your gas mileage about 15 percent by driving at 55 mph rather than 65 mph.
- Use your air conditioning only when necessary. Roll down the windows or open the air vents to keep your car comfortable on not-so-hot days.
- Use overdrive. If your car is equipped with overdrive gearing (on 5- speed manual transmissions and 4-speed automatic transmissions), be sure to make use of the overdrive gear as soon as your speed is high enough. If you have a manual transmission, the lower the shift speed, the better the fuel economy. Your owner’s manual will give you further information.
- Keep tires properly inflated and aligned. Periodic wheel alignments and keeping tires inflated to the maximum recommended pressure can improve your gas mileage.
- Get regular engine tuneups and car maintenance checks. Tuneups improve performance as well as gas mileage. Check your owner’s manual for recommended maintenance schedules. By following the manufacturer’s recommendations, you should avoid fuel economy problems due to worn spark plugs, dragging brakes, low transmission fluid, or the transmission not going into high gear.
