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).
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.
The carbon percentage of octane (C 8 H 18 ), a stand-in for gasoline, and hexadecane (C 16 H 34 ), a stand-in for diesel, are 84.2% and 85.0% respectively. The amount of carbon dioxide produced from gasoline and diesel and therefore the carbon pricing, are also both very similar on a mass basis.

Premium fuel is a higher octane fuel in the range of 91-94 octane. This compares to regular grade gasoline which is 87 octane. Higher octane fuel aims to provide greater fuel-burning stability to protect engines from the damage caused by engine knock –also known as abnormal combustion.
Dec 8, 2020 · By blending pump premium (or 91 if you like) with E85, you can create a custom blend of high-octane fuel. Cost Savings Through Better Chemistry. Simply put, if you mix 5 gallons of 91 octane pump gas with 5 gallons of E85, you get 10 gallons of a 96-octane fuel that’s very close to E50, or 50-percent ethanol and 50-percent gasoline.
Jun 28, 2017 · According to the latest data from AAA (which tracks fuel prices daily instead of the EIA’s weekly), premium costs $2.80 per gallon on average, or 60 cents more than regular.
