So I was filling up the car last night when I seen a sticker on the pump saying, “Gas can contain up to 10% Ethanol”. Will this affect my tune at all? Is this in all the gas? I put some miles on the car last night and it ran really well with the gas…may have just been the cool air though.
Haven’t they been doing that for awhile now?
I thought it was only in the 94, but that is gone now…
My hatch Would Run better on 94 octane I had a rich tune thats prob why…
This could effect your tune Prob for the better though
normal gas has up to about a 20% mix of ethanol depending on where you go.
its been like that for a long time at sunoco.
It’s the summer “driving season” blend.
I’ve always heard that, which is reason enough for me to not use it. Ethanol is just a quick easy way to raise octane and drop fuel economy.
Maybe it is in all gasoline, but it’s not advertised anywhere else
