Gas per Gallon

Answer 1

You mean miles per gallon. Fill up your gas tank and set your odometer to 0.000. Drive your car until it needs gas again, and divide the miles you drove, by the amount of gallons you just put in. Example: You drive 300 miles, then put in 10 gallons; 300 divided by 10 is 30. You get 30 miles per gallon. It is a method to see how efficient your car uses gasoline.

This is sort of a efficiency quotient to describe how economically your car saves on gas. If you drive mostly freeway you avoid stop and go traffic and waste less gas, just sitting there idling at traffic lights and stop signs. The more cylinders your car has, chances are the more gas you waste; you're trading off power for economy. Buy a four cylinder car, and if you can, use the freeway.
