Re: Carb problems following needle shim mod
91 octane under the RON must be regular. MON regular octane must be must be 83. 91+83=174/2=87 Average Octane in the US
Some countries (like Canada) use just the RON measurement. All the same stuff measured with a different scale. Also, what thay are saying is don't use less than "91 RON octane regular", as 60 octane donkey piss is available in some asian subcontinent areas. Confusing, eh??
