Well, I looked at the error for my MPG meter this year. Seems like my average error is 0% (Yes you read that right). With average deviations between -2% and 1%. Pretty darn tight. The only time the meter is off is when I spend half a tank solidly in the city, then the other half solidy freeway driving. Then I get variances of up to 9% off between Dash and Actual.
