The European and American octane numbers are different for the same stuff.

America uses the MON + RON/2 to achieve the stated octane number, whereas Europe only uses the RON (?? one or the other) number.

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.

Premium here in Florida is 20 cents per gallon higher per gallon on average.
