   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.

   Between 2010 and 2017, the U.S. average retail price difference between premium gasoline and regular gasoline doubled, from approximately $0.25 per gallon (gal) to $0.50/gal. However, in the 15 years before that period, from 1995 and 2010, the U.S. average premium to regular price spread increased $0.05/gal.

   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).

   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 26, 2023 · Isooctane, specifically 2,2,4-trimethylpentane, is a highly branched isomer of octane, used as a reference standard in fuel ratings. While octane is a general term for C8H18 compounds in gasoline, isooctane's role is more specific as a benchmark for anti-knock properties in fuel.
