Want to Save on Fuel? Slow Down!
(Fox 8 News) - Could driving slower save you on gas? Some say yes, as much as 55 cents a gallon. A fuel injection technician advises that for every 10 mph you drive over 60, it's like spending an additional 55 cents per gallon of gas.

A car's drive train is optimized for a particular speed. In general, you can tell what speed that is by the value that is at the top of your speedometer. More technically, the speed that you can maintain over slightly variable ground, with a constant throttle position, and with the transmission in its highest gear is the one to which your drive train is optimized. Many factors go into this: the weight of the car, the gearing ratio of the transaxle and the rear end (if the car is rear-wheel drive), even the size of your tires. As well, fidelity to the actual octane grade will make a huge difference in your gas mileage. The oil companies are only required to average their octane ratings and it can vary greatly between gas stations, between different gas deliveries to the same station, and even with how long the gas has been in the station's tanks.
For example, my Corolla gets better gas mileage at 65 than it does at 55. My Jaguar gets better gas mileage at 90 than it does at 70.
But go ahead and drive 55. Just stay out of the left lane.
