I prefer BP, then Sunoco. I use Shell pretty often because there is a Shell station 3.5 miles away from the house. I have always ran the highest octane available.
I have yet again learned something

but that leads to a question....oops...Since I never thought to listen to the bike about the fuel, I haven't noticed any pinging, except for on one very hot day last summer (100+*), heavy traffic, someone shut down the highway, so I took the same alternate route that everyone else between Cincinnati & Dayton took. Slow going. My question is when I fill up again, and listen to the bike, I'm thinking of trying 2 tanks of each one to see which one the bike sounds happiest with. Is that overkill, should I notice a difference if any with one tank?
