There is another type of octane rating, called Motor Octane Number (MON), or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load as it is done at 900 rpm instead of the 600 rpm of the RON<ref>http://www.texacoursa.com/glossary/r.html</ref><ref>http://www.texacoursa.com/glossary/m.html</ref>.
Different kinds of fuels have different combinations of hydrocarbons. Isooctane, or âoctane,â is resistant to the spontaneous exploding, so the higher the octane, the less chance there is to experience this knocking in the engine. If you look at the gas pumps at any gas station, the âPremiumâ fuel has a higher octane level on it. The premium octane is usually going to sit at around 91, while the regular gasoline is right around 85 to 87.
