Not linear. Never tried to accurately measure it. Have changed chain and
mpg improved by 5+% but the numbers I've seen are ALL over the place.
Too many variables. I have moved the actual pump timing of a well
running engine by almost 4 degrees and seen ABSOLUTELY no difference in
fuel economy. In an engine not running nearly so well, a change of 2
degrees resulted in detectable improvement in fuel economy.
