So i've seen the difference first hand between the 10% ethanol gas that all stations around here have and regular 100% gas. Normally i get 280 out of a tank with the light being on for a bit. Now i have 280 and 1/4 tank still showing. So i read around and saw that you can tweak your engine timing for this ethanol blend to make it run much more like regular gas. Has anyone played with this? What were your results like?
