What do you choose and why?
Well, if I'm looking for a fuel for something like a standby generator where I need the fuel to last a long time without degrading, I'd go for a non-oxygenated fuel.
For EVERYTHING else, including cars that sit a few months (but not a year or more...) at a time, I'd go with E10. I was a huge E10 skeptic but after living with the stuff for 15 years, I believe E10 is far, far better than MTBE-boosted fuel ever was in terms of performance for the dollar, and keeping the fuel system clean and healthy. I've had far fewer fuel system issues on E10 than I did back during the MTBE (and tetraethyl lead, for that matter) years.
