I found my car seems to mysteriously and indefinitely gain .1mpg or .3% every 4-5 miles I go even after the initial 15miles or so of warm up. I've wondered if it might be from increased rake as the fuel tank gets lighter. Whatever the reason it makes it so I don't think I could pick out results that have an impact of less than about 1% on the vehicle
