There is no easy solution to saving money on gas. My usual mileage per week is 400 - 500 km, Last week I drove 230 km and cut my driving down to half along with my gas bill. In Europe where gas has been expensive for years, people are more careful with their driving and gas consumption. It is simple, minimize your driving, plan your trips. Do more than one errand per trip, cut down on unnecessary driving. It was quite easy to do. I plan to keep this up as long as I can.
