For those of you that all of the gas stations around you have gone 10% ethanol, how has the gas affected your motor? Is it running the same? Less power? Better gas mileage? It seems that my motor is acting a bit iffy since the switch. I'm noticing alot of light spark knock. Anyone else notice it?

You are going to be quite disappointed if you expect to get better mileage off this stuff.....

I wouldn't think you could see much difference from 10%, but theoretically you should lose around 1 mpg if you were getting 20 mpg before, based on energy content. If you're actually getting some detonation it's time to find a different gas.
