Miles per gallon has become one of the most important statistics when it comes to your car. Here's an easy way to figure out your MPG.

Step 1: Fill up and record mileage
Fill up your car with gas and record the current mileage on a piece of paper.

Step 2: Drive until you need gas again
Drive you car until you need to get gas again.

Tip
Drive your daily routine rather than driving around just to burn up gas.

Step 3: Fill up again and record the gallons
Fill up again and record the number of gallons you put in. This number will be the number of gallons you used since the last fill up.

Step 4: Record your mileage
Write down your car's mileage after the second fill up.

Step 5: Subtract the mileage difference
Subtract the mileage from the first fill-up from the mileage from the second fill-up. This will tell you how many miles you drove between fill ups.

Step 6: Divide by gallons
Divide the mileage difference by the number of gallons you used. This is your MPG.

Aggressive driving with lots of speeding and rapid acceleration can lower your gas mileage by 33 percent on the highway and 5 percent in city driving.
