Phase 2 of this report models possible outcomes of a change in motor gasoline octane requirements and changes in demand for octane. To assess octane costs, this study examines trends at the national, the Petroleum Administration for Defense District (PADD), and the regional wholesale market levels.
We can model the heating values by using standard heats of combustion 1 for iso-octane and cetane. Engineers distinguish between higher heating value (HHV) 1 and lower heating value (LHV) 1 of a fuel.

Octane costs and values are often described in terms of dollars per octane-barrel ($/AKI-b).21 To measure the cost of producing incremental octane, we calculate the cost of producing an incremental barrel of premium gasoline (CTP) by raising reformer severity (Figure 29, red and black lines).
