I'm thinking the higher the octane the slower the burn rate so more igntion lead would be required? But then again what I usually think is wrong. 5517458-moretwist.jpg (83 downloads)

The higher the number the more resistant to detonation it is. AvGas is VERRY "flammable" and also has an octane rating of around 110. Octane is an actual chemical:CH3(CH2)6CH3 However - Octane Rating (IE:92, 110, etc) is NOT an indication of how much octine is contained in a part of gasoline. It is just a reference to anti knock properties. Hell B!tch Racing Co.
