   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 market for motor gasoline is global, and the U.S. gasoline market is interconnected with the global gasoline market through imports and exports.

   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).

   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.

   On Friday, OPIS indicated about $1.42/gal for normal and $1.47/gal for iso, for a differential of about a nickel. As shown in Figure #3, that differential varies widely with the relative supply/demand balances for the two products. Iso has traded from a low of about a penny under normal, to as much as 60 cnts/gal over normal.

   Jul 17, 2007 · Octane, or iso-octane is a measure of how much compression the fuel-air mixture will stand before it explodes (pinging) instead of burning, as it must in an internal combustion engine.

   How much does octane cost?

   • Octane values have increased from about 1 $/RON-b to 2.75 $/ RON-b as of 2017 (Figure 57, blue line represents octane cost while the red dashed line represents the crude cost). Unlike the U.S (Section 6.5, Figure 29), octane costs have not dropped back down to 2011 levels.

   How do you calculate octane cost?

   • 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).

   Do octane costs drop back to 2011 levels?

   • Unlike the U.S (Section 6.5, Figure 29), octane costs have not dropped back down to 2011 levels. Although Europe does supply gasoline to PADD 1 in the United States, the U.S. spot octane costs reflect the economics of the U.S. Gulf Coast (PADD 3) refineries, and not European differentials.

   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.
