I have been running octane engine since 1981. The spread between RON and MON varies and depends on the crude composition and the cut the refinery makes to create the gasolines. Back in the day they rated octane by reaserch only because that is the only engine they had. It strikes me as strange that soemeone would be recommending a 93 RON. Propbably just needs an editorial change. I don't see why an 87 pump octane wouldn't fit the bill. Now a days the darn low heat of combustion(BTU) from the ethanol, messes with engines, but they don't care because they get cheap octane. Actually the whole octane measurement system needs to be revised to allow for the down grading that we get from etahnol.
