After advancing the cam on my Vigor 9 degrees, my next fill-up calculated out at 25.99 mpg! That's over 60% above EPA combined estimate. My historical average mpg is just over 20 mpg. This is on E85 which was only $2.98/gal (June 5, 2008) so to break-even I would have had to get 33 mpg on gasoline.
I know this could be a fluke....but I hope to God it's not!
