You mean cetane, not octane. Opposite measures, more or less -- octane is a measure of resistance to pre-ignition (knocking), relevant to gasoline, while cetane measures combustibility, relevant to diesel engines. (These are rough definitions, which someone will undoubtedly correct me for.)

Octaine: Ability to RESIST ignition due to heat and compression
CETANE: Ability to IGNITE due to heat and compression,
