How can I minimize fuel usage?

Follow maintenance schedules for your car. Keep speeds down. Skip the trip. Don't use the air conditioner unnecessarily. Car pool or share rides. Dump the need for a large vehicle. The advertisers have us convinced that we are not safe unless we are surrounded with 4 tons of SUV. We fuel retailers love SUV's. For me, I fill two times per week (not an SUV) instead of one. I fool myself into thinking that I use less gas. Remember, the vehicle does not cost money when you fill it with gas. It costs money when you turn the key.
