Then fill it up with a reference fuel like a 93 (93% iso-octane, 7% n-heptane) and estimate the knock while that burns.

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).
