Figuring out your gas mileage yourself is very easy to do, and if you remember this simple method you can figure it out for yourself every time you fill up your tank.
Here’s how — we’re going to figure out how many miles you drive between fill-ups, then we’re going to figure out how much gas you used. Finally, we’re going to do some really simple math and come up with a very accurate estimate of your gas mileage.
All you’ll need is a piece of paper, a simple calculator (the one in your cell phone will work fine), and a minute or two at the gas station right after you fill up.
Step 1: Fill your gas tank completely full.
Step 2: Before you leave the gas station, you need to reset your trip odometer to “0” (zero). If you don’t know how to do that, or if you don’t have a trip odometer, then you need to write down your car’s total miles and save the piece of paper you write it on.
Step 3: Drive around normally until it’s time to put gas in your car.
Step 4: Fill your gas tank completely full.
Step 5: Figure out how many miles you’ve driven since your last fill-up. You can look at your trip odometer for the answer, or you can figure out how far you’ve driven using the scrap of paper from step 2 and your calculator. Write down that mileage and go to the next step.
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: Now that you know how far you’ve driven since your last fill-up, it’s time to figure out how much gas you’ve used. This is easy — just look at the gas pump. You’ll see exactly how many gallons of gas you just put in your car — that’s the amount of gas you used since your last fill-up. Make sure to write down the amount of gas you used, and make sure to include the numbers after the decimal point.
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.
If you want to know what your car’s mileage should be according to the EPA, you can look it up online. Just find your car’s year, make, and model.
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.
The best part about this method is that you can figure out your gas mileage every time you fill up — just make sure that you reset your trip odometer or write down your mileage every time you fill up with gas.
