10% Ethanol ?????

Stopped at my normal gas station this morning and am happily pumping away (7cents off on Premium on Tuesdays) when I notice they've re-logo'd all the pumps. They now say "93 Octane (with 10% ethanol)"

!!!!?????!!!!!!

I immediately stopped pumping. I'm sure it's a non-issue with a stock car, but how is that additive going to affect my 93-Octane-tuned pride and joy? Should I shy away from it, or is this OK?? Does affect the actual octane rating?

I need some gas experts!! um-gasoline, that is.

EDIT: Yeah, let me add that being in the sunny south, we don't run winter mixes or such. I guess maybe this is common elsewhere????


2005 Satin Silver GT 5spd, IUP, ICAP, bullits, active alarm, lug locks, side a!rbags, shaker 500, XM Roady 2, JLT cold air, Xcal2 w/ SCT 93 oct tune, & custom fab'd ram air duct, BMR Sway Bars, Hurst Competition plus shifter

I remember a couple years back they were adding Ethanol to gas, but for some reason stopped it. Up here in north country we get summer mixes to keep down the smog. I think you guys have it year round.
Funny because I read that it takes more energy to produce Ethanol from the start that regular gas.
Did you happen to check the manual on Ethanol in these cars?

I haven't yet, but I will at lunch. My concern is the advanced tune. I'd bet that if it was stock, it would have to be able to run it, probabaly per some gov't reg. But, with the aftermarket tune, I worry. Now I'm thinking- how many stations are selling the same thing here and just not advertising??

It use to be only the cheaper places. When speedway or clark would be 10 cents cheaper than amoco shell it was because speedway/clark and such used 10% ethanol. Now Im pretty sure its government mandated they all contain 10%. I want to say this was about 10-15 years ago

Premium never used to have it. I think it was around 97' that all the grades went to 10% enthanol.
