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.

normal gas has up to about a 20% mix of ethanol depending on where you go.

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
