Default Ethanol and supercharging
Rumor around my part of the country is that all gas will have a 10% ethanol content within 90 days. Costco even has the decals ready to install on their pumps. Will this have any effect on our supercharged cars?

Poorer fuel mileage Also bad on seals.

I need to double check, but I thought there was already a mix maybe 93/7 mix today.

Question: Since ethanol is much higher in octane all things equal the octane of the final product should go higher... why is it not?

I am guessing the base product (gasoline) octane is lower.
