I have a friend that built a rig to remove the 10% ethanol from gas by adding water. He does 5 gal at a time. Adds 2 qts water and then drains off 1 gal water/ethanol. He uses the straight gas in his outboard, chainsaw, mower, etc. We went fishing yesterday and the outboard ran great.
My question is what happens to the octane level of the fuel when he does that. If he starts with 87 octane does it go up or down when the ethanol is removed ?? Just curious.
