Should i run fuel with ethanol or fuel without ethanol.?
My feeling is that you would be better off not having the ethanol. It attracts water and it's hard on rubber fuel components (lines, fuel pump diaphragm, carb needle/seat assembly, accelerator pump diaphragm, etc). Those parts will tend to wear out quicker.
If you drive it all the time, the water should not be much of an issue. I have '71 Cutlass that may only get refueled every other month. That gives time for water to accumulate and cause corrosion.
If it's no more than 10% you probably won't notice much difference. Going over that is uncharted territory and is the subject of current debate with the EPA, ethanol producers, and car manufacturers.
