Octane Booster Fuel Additive

Look closely at your fuel pump at the station and tell us if it's rated RON, MON, or R+M/2. In the states, it's R+M/2 (RON plus MON divided by 2). I'm guessing that you're seeing RON ratings which are much higher.

Ok I will check that as soon as I can! Oh do you mean (R+M)/2 ?
