Hey guys,
Got so excited reading this thread i had to join nairaland cos it's right up my alley. Echeozo you are only half right about the RON ratings you see at the pump. It all depends on where you live and the state regulations concerning octane. In Phoenix, Arizona where I lived until a few months ago we had 93 RON at the pump (which we even believed was not high enough; some states have higher) because the ambient temps make the fuel vaporise more easily increasing the possibility of detonation at increased engine speeds but in colder states or at higher elevations those ratings are just fine.
