89 Octane okay?????

[emory70]

the octane number that's on the gas pump isn't the actual octane number. it's an average of the real number and the research number. that info used to be printed on the octane rating sticker on the gas pumps. don't know if it is anymore.

MON is the Motor Octane Number and the RON is the Research Octane Number. One is numerically lower than the other for the same stuff.

SOS, regular is regular is regular is regular.... Use the lowest possible grade available. It will run on 60 octane cat piss if you can find it.

Let the instigator stop his behavior and the rest of this will stop. Don't blame anyone else for responding to it.
