Increased Mileage

Improve your gas mileage by filling up the gasoline tank in your car in the summer. Don’t overfill your tank. Spilling gasoline on the ground just doesn’t improve gas mileage. Gasoline includes liquid gasoline and gasoline vapors.

In the summer time it is possible for some of the liquid gasoline to turn into vapors inside your gas tank. To avoid this fill the tank to the normal full level and try to keep it there. This reduces the amount of space available for gasoline vapors and actually increases gasoline mileage.

You can also improve gasoline mileage by keeping the tires of your vehicle full of air. Check the tires before you have traveled a long distance or before it gets to warm during the day. Warm air expands in the tires and may give a slightly false reading. Keeping the tires full with air may save up to 5 per cent on your total gas mileage.
