Just be careful storing long term as the article states tend to grab water and spoil.

I know chainsaws trimmers and small motors seem to do the worst with it .

3% doesn't sound like much, BUT when that 3% equals 10 or 12 hp, most racers would give their left

for an extra 10 hp..

You are right! thats actually HUGE! but i wonder if it is real. Has anyone done a dyno test of the 10% ethanol gas vs say, race gas at the same octane in the street octane levels (say , 91- 92 )

i wonder if it really can make 3% more power at the wheels!
