- Radial tires can cut 3-4% of your fuel bill.

- If you own a pick-up truck, remove your tailgate (or put it down) for any highway driving. The tailgate acts like a drag chute giving you very poor fuel economy as much as a 15% loss). If you don't want to remove your tailgate; you can use a soft net-type gate or get a bed cover to almost eliminate the drag chute affect.

- Expect up to 10% drop in fuel economy in heavy rains, and 1-2% for every 10 degree Fahrenheit drop in temperature.

- Fuel consumption is heavy in the first 20 minutes after start-up, especially in winter months, because the car hasn't fully warmed up to its efficient temperature. To reduce this effect, use a block heater. Purchase one with a timer so it comes on 2-3 hours before you have to start the car. A warmer engine means easier starting and better fuel economy. This also reduces pollution to our environment since the car's emissions are much higher before it warms up.

- Avoid driving with an open sunroof or windows at highway speeds. It increases aerodynamic drag and wastes fuel (up to 8%). Use the vehicle's flow-through ventilation to provide fresh air for passengers.
