2 Stroke Fuel info.

[skegpro]

Shell 91 has a RON of 95 and MON of 91. In Canada and the US we use a 4-6 number difference between RON and Mon. Elsewhere in the world uses 8-12 number difference.

How did you find this info? I have looked everywhere.

So I read that as shell displays the MON value on the pumps not the RON.

This is Uganda too, wonder if this holds true in Canada.

Canada and US display MON numbers. I’m trying to find the thread from last year about this. It was a very good thread that had all the detailed info straight from the manufacturers. I just have to remember which site it was on lol.

This was from wiki which is never 100% but It does state it’s an average of the 2

North American fuel standards calculate octane as the average of RON and MON.
