McPatrick Supporting Member Join Date: May 2007 Posts: 319	mpg and weight I was wondering if there is a theoratical weight to calculate the mpg at a given weight at the same speed if one mpg number and one weight number is given. Say I know I get 50 mpg at 65 mph with a car that weighs 2200. I look at my car and wonder what the mpg would be at the same speed if I manage to take off 100 lbs of the weight. Is there a formula for this at all?
