Driving 55-60 on the freeway can help a lot, frequent lane changes reduce mileage. Strangely using acetone in the gasoline will help mileage, all the disclaimers about it either being harmful for the car or not increasing mileage are wrong. My car is rated 28/30 mpg, I get 38 using acetone, it has to be pure and the mixture must be right, it usually takes a couple tanks with it for it to really get better, I use to struggle to get 28 on the freeway. Also tune up are good, check tire pressure, going over recommended but under maximum is a good was to improve mileage. Replacing spark plugs, air filters and changing to synthetic oil with 5w-20 or 5w-30 will help.
