Why are you using 91 when the engine is designed and tuned for 93?
I know they say it can safely run on 91 but clearly 93 and higher is the fuel to use unless you get caught out somewhere with only low octane available.

Only the Shell 91 is Ethanol free here that is why I use it over the petro 94, 94 has 10% Ethanol. Sure it is designed for 93+ but I does say 91 is perfectly fine and I would rather run the 91 with no ethanol
