   premium gasoline prices started in 2013 and has continued through the study period. A narrowing price spread between regular gasoline and premium gasoline in the spot market, or the first point of sale after being produced in a refinery, indicates decreasing costs of producing octane at U.S. refineries, not increasing.

   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).

   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.

   What Octane is premium gasoline?

   • Gasoline with a 95 RON typically will have a 90 to 91 AKI, meeting the EIA definition of premium. In most U.S. markets, the premium gasoline supplied is in the range of 91 AKI to 93 AKI. In European and some other markets, limited volumes of 98 RON gasoline are sold. These are similar in octane quality to a 93 AKI U.S. premium gasoline.

   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.
