I saved one of the easiest and best for last. Many times poor fuel economy is your fault. Yep, that’s what I said. The way you drive has a direct effect on fuel economy. If you have a lead foot, make sure you have a high credit card limit, because you’ll be spending a lot more at the pump. If you want an easy way to save fuel, slow down, don’t race at stop lights, and take it easy on your vehicle. Do it for one tank of gas and see if you go farther. I bet you do.
