Calculating your gas mileage is easy. Follow these steps and you will be able to calculate your own gas mileage each time you fill up the tank.

First, you need to figure out the number of miles between each fill-up. Second, you will figure out how much gas was used. Finally, you will estimate your gas mileage, using only simple math. To get started, you will need a calculator, a piece of paper, and pen or pencil.

Step 1: Fill your gas tank completely full.

Step 2: Reset your trip odometer back to zero. If you are unable to do this, then write down the mileage of your car.

Step 3: You should drive your car as you normally would on a daily basis.

Step 4: Fill your gas tank completely full.

Step 5: Now you need to figure out the number of miles between the two fill-ups. If you reset your trip odometer, note the number of miles you have driven since resetting it. If you wrote down your car’s mileage on paper, subtract that number from the current mileage on your car. This is the number of miles you have driven between the last two fill-ups. On the piece of paper, write down this number.

NOTE: Keep in mind that most of the time, the number you write down in step 5 should be between 100-500 miles. If you’ve driven a lot more or a lot less, there might be a problem with your math (or you’re getting really good mileage).

Step 6: Next you need to figure out how much gas you have used between fill-ups. To do this, all you have to do is to look at the pump. The number of gallons on the gas pump is how much gas you used between fill-ups. Write down the number of gallons with a few numbers after the decimal point on the piece of paper.

Step 7: Using your calculator, divide the number of miles you’ve driven by the number of gallons of gas you just bought. The resulting number is your gas mileage!

If you’re driving a truck or large SUV, your mileage should be between 12 and 20. If you’re driving a small SUV or a large car, your mileage should be between 18 and 25. If you’re driving a mid-size or compact car, your mileage should be between 25 and 35. If you’re driving a scooter, your mileage should be really good and you shouldn’t worry about it. Also, if you car’s mileage is a lot more or a lot less than we’ve listed, there might be something wrong with your math or your car.
