Sorry it took so long to get back. I didn't know it was there. There is no secret. I think the Aveo is just what it's designed to be. I have slowed down, but drive 26 miles one way to work and just plan for extra time. The more I drive the car the better I know it and the scangauge helps a good deal. The only mods I currently have are the rear and passenger seat removed. I never carry passengers. I only use it for work and to carry my kayak on the way home. I EOC when I can.

I am really impressed with your Aveo mileage, given the oft bandied notion that they get lousy mileage... what's your secret?
