We have two refineries on the outskirts of town, one's Tesoro and the other is Shell. All the road tankers coming out of the refineries are generic - no gasoline brand names.
I get the impression from what one or two refinery employees have said is that the gas reaching the tanker fill hydrant system is the same for all, and a initial shot of the specific buyer's proprietary additives goes into the empty tankers before the gasoline is fed in. AFAIK, the ethanol percentage is in the gasoline stock, not the additive mix.
Maybe someone on the forum who works in the refinery industry could clarify?
BTW, CB1000rider, the Onan book for my '02 MH generator (which is probably an '01 build) specifically says not to use ethanol treated fuel. When (if?) I get the generator running again, the carb bowl will get drained each time it's shut down. Im hoping that, If I do need to buy a replacement carb, it will be ethanol compatible.
