Did you ever run out of gas before reaching a gas station?

Or did you reach a gas station just in the nick of time?

If you ever realize that you're running on fumes with no gas station in sight, reducing your speed will extend the range for the fuel that you have remaining in the tank.

Reduce your speed to about 42 mph or 70 km/hr with your vehicle in high gear and you will achieve what's known as the 'maximum range speed'.

This is the speed which yields the maximum miles per gallon you can achieve with your car.

Another way of finding that 'max range' speed is to note the speed where your car's transmission shifts into high gear or overdrive, then add 5 mph or 5 km/hr to that speed, which will then keep the transmission in that gear without cycling in and out of gear.

If you drive right on 42mph or 70k, the transmission will cycle in and out of gear which you don't want, but adding the extra 5 keeps it in high gear/overdrive.

Then, turn on the cruise control and set the cruise speed at that desired value because it can hold it more accurately than you can and keep it on until you find a gas station.

If you run out of gas, at least you'll know that you don't have to walk as far as you'd otherwise have to had you raced like hell to run out of gas getting there!
