I go with the best I can get. Non ethanol If it is available in a 91 or greater octane. If not I use Shell premium first choice, I always run premium top tier fuel and tune ignition advance for best performance.

Premium pump gas will work. Non-ethanol if at all possible.

And if you can’t find non ethanol run an additive to negate the ill effects of the ethanol. I use marine 2 cycle oil added with every fill up. At least 1oz per every five gallons.
