Maybe I'm mixed up, but my thinking is that IH at that time recomended 87 octane gas using the research formula. If the motor formula was used the octane rating for the same gas would be lower. Wouldn't the octane rating on todays pumps now be a average of the two testing types? So the 87 on todays pumps should be lower than what the reseach octane # for the same gas would be. Or ROM 87 gas = a lower reading for the same gas using the other two methods . Or If rom was 87 the mom may be 77 or so, wouldn't that make RM2 on todays pumps 82? Is my thinking messed up?
