- This is getting a little off-topic, but having a chem degree, I have to inject
- my two bits 8-) Octane numbers are based on the two reference points with
- n-heptane (straight chain of 7 carbons) at 0 and 2,2,4-trimethylpentane
- (isooctane) as 100. Many hydrocarbons give 100+ ratings since they're
- more branched/aromatic than isooctane. e.g. Benzene is rated 106, toluene
- is rated 120.
