I get 3mpg less on E then pump 93. That is comparing E80 to pump. On E60 it's about the same. E40 seems to be a little better on fuel mileage. E40 also starts to smell more like pump fuel where E60 smells like the sauce. The exhaust tips also stay a lot cleaner on E60+ vs E40 or lower. However there isn't much gains or advantage to run anything more then E60 from a performance stand point. I believe this is why E60 is considered the "sweet spot".

Thanks, King. When the time comes I will be looking to do the same in creating a 'garage mix' to find that sweet spot.
