From the state of Montana
A. The antiknock or octane rating of a fuel is a measure of its resistance to knock. The antiknock requirements of an engine depend on numerous factors, including engine design, operation, and atmospheric conditions. Automobiles manufactured prior to 1984 could, due to Montana's altitude, operate on a fuel having a lower octane rating and achieve the same performance that other cars using 87 octane fuel had at sea level. Since the advent of sophisticated engine control technology starting in 1984, however, the effect of altitude upon octane rating has declined to the extent that the newest cars require the listed octane as found in the owners manual regardless of the altitude.
