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>.
Octane rating of fuel is the quality rating the resistance of a fuel to self combust at, IE dieseling. There are three octane rating systems.The first two rate the quality of the fuel at different temperatures and the third, the one we use in the United States of America, uses the average of the two.ctane rating is the resistance to burning. For example (not real number) a gas with an octane rating of 50 will burn at 100 degrees Fahrenheit whereas a gas with an octane ra â¦ ting of 100 will burn at 200 degrees Fahrenheit. Higher the octane number the harder it is to burn.
