pokeatyou2 Posted March 15, 2007 Report Posted March 15, 2007 im from australia just curious when yas are talking on here about octane in fuels available at the pump eg 91 and 93 what octane rating are these based on RON or MON just curious about the fuel available here they are rated on RON 91 95 and 98 mainly asking because a fuel has just become available with an RON octane rating of 100 alao will fuels with 5% ethanol be bad for my shee Quote

The RON is generally substantially higher than the MON number. This is the reason for the average of the two in that no one has ever decided which was actually better or correct. 5% Ethyl is fine. About 20% is where you will start to have side effects of the hygroscopic fuel and you would need to flush your fuel system everytime you ride. You will not have problems with 5% and many fuels in the US already have 5% and it is not even stated at the pump. I would expect your 100 RON fuel to come out to about our 93 octane fuel in the US once you derate it with the MON number. Brandon Quote
