I use the Gas Buddy App. It works decent and once in a while will find you a great deal so you can take advantage and fill up. I live in New England and drive 80 miles round trip for work. It's costing me around $75 a week. I'm actually in the process of getting a more fuel efficient car. Unfortunately I will have to give up my AWD to do so.
