For the record - Europe only reports RON (research octane), which is always higher than MON (motor octane). The US reports [RON + MON]/2, the average of the two. For example, an octane rating of 96 in Europe is roughly equivalent to an octane rating of 92 in the US.

RON is a measure of octane under mild engine conditions, MON a measure under heavy load/high speed conditions.

Mardibloke, detuned engines? Hmm, doubt it, you have to remember that we Americans like our cars to burn as much gas as possible :). Also, if you feel cheated for power when driving in the US, try a 426 Hemi 'Cuda next time you're here (if you can find one). Just make sure you buy a neck brace before you drive it.

Not that any of that had anything to do with empeg stuff, but I'm at work and bored.
