I have the choice of BP, Shell, Mobil, Sunoco, Speedway, Citgo, RaceTrac, Marathon, BJs, Circle K, Hess, Site, and Petro Stop.
I used to exclusively use Shell, basically because of their good standards and super high quality, high detergent, top tier fuel...but just recently, all the Shells here have ethanol now.
My mileage dropped a full 2 mpg from 10-15% ethanol, that was a BIG hell no. So now I use, in ranking order, BP, Mobil, Sunoco, Speedway, and RaceTrac. I NEVER use citgo, if you want to know why, google about citgo, and the rest are not names I trust...even if it is JUST gasoline. Because of the size of my tank, I really don't fill that often, so it takes quite a while for me to test several different fuels...
BP is now getting me mileage I barely even came CLOSE to before...so definitely won't be using shell anymore
Sorry shell, you did it to yourself. I still only get about 24.5 mpg at 65, but its alot better than the ~20-21 i was getting with shell.
I guess I'll just seafoam more often to replace the benefits of the top tier fuel.
I feel pretty bad for people that live in areas where its ALL ethanol fuel....and unfortunately, it looks like its coming in around here now.
