Someone here awhile back posted asking about the computer mileage from the car computer vs manual calculation. And also with ECO on and off. I can't seem to find the post now. Anyhow I thought I'd put my first 6 month figures up.When I fill up, it's 90% of the time at the same gas station. Always level, and always a couple of clicks after auto shut off. It does appear that the car computer is a slightly generous.
