Optimax Extreme What’s Needed?

It is true ethanol is highly corrosive but only in concentrations way beyond what the fuel will contain. Out of all the coatings we manufacture we can't give any warrenty on fuel tank linings for anything with over 50% ethanol as it will just degrade organics. Ethanol does behave differently when solvated in other hydrophobic solvents (fuel) so it's a fairly good bet the fuel system will be fine.

i agree 100% with sydney kid.

im curious as to how ethanol, a polar molecule is dissolved in a non-polar substance like pump fuel, which is a hydrocarbon ?

Ask petroleum engineer, obviously they manage it somehow.

Will an industrial chemist suffice?

Ethanol has a polar OH group, but also has an ethylene (alkane non-polar) chain attached. It's this alkane chain that allows the ethanol to become miscible with the fuel. Methanol will not blend as it doesn't have a big enough non-polar group....each CH group you add to an alcohol gives it a more non-polar nature...Octanol is fairly non-polar and will not actually mix with water...you have propanol and butanol which sit between.
