I use my phone calculator to figure out my gas mileage every time I fill up. I reset the trip odometer when I fill up and I just divide that number by the amount of gas I put in to see if I got decent mileage on that certain tank of gas. I know, it's kind of anal, but it's just something I do.
Saving on gasoline requires great effort so I was impressed by this simple move. Do you have a tip for readers? Join our How Do You Save? group and share your helpful suggestions. Here's a detailed guide to posting questions or posts to groups if you are new to the PopSugar Community.
