So we know about the Turbo's HP/Torque rating at what Mazda refers to as regular/87 vs Premium/93. Do we know if it needs 93 to get that additional power? Meaning no incremental increase at 91, but rather it's all or nothing and needs 93? - in other words, no increase realized at 'only' 91 octane?
We have all read the same articles from Consumer Reports and others about premium gas for decades. I hope this doesn't devolve in to questions about octane that I am not asking. I can't stop you, but please let's not go off the rails with info on octane, knocking, predetonation, waste of money, engine 'learns', modern engines, as well as other non sequiturs, but rather remember this turbo actually is engineered to provide different output based on octane.
Just the simple question, all or nothing from 87 to 93, or incremental gains at 91?
EDIT: Oops, I think I posted the same question weeks after I bought the car.
