Did you check wind direction?

Probably not grounded in fact. Unless both have a refinery close by, they both come from the same place. We have two local, one Sunoco, other is Holley. All fuel around here comes from one or the other. I have customers from both places. They tell me everybodie's of a given octane comes out of the same storage tanks.

Might like a degree or two more timing. Just have to test that.

We have.100% pump gas around here. Stations offering that get a few cents per gallon more. I don't run that E-anything unless I just can't find anything else. The difference in mileage almost pays the difference, and I don't like running that crap through my stuff that crap is only a good deal for the corn farmers. If you have to burn more of it to go the same distance, I don't see the big advantage. I think EPA is about to learn that also. About 2 MPG difference in my wife's Lexus.
