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.

In 2017, the U.S. average retail premium gasoline price was $0.50 per gallon (gal) more than the price of regular gasoline. The difference between premium gasoline and regular gasoline prices began to increase in approximately 2010. The cause of this price spread may be the result of a change in U.S. refinery operations or retail gasoline pricing d...
In the United States, since approximately 2010, the price difference between regular gasoline with an octane rating, or Anti–Knock Index (AKI), of 87, and premium gasoline with an AKI of 91 has been increasing. Between 2010 and 2017, the U.S. average retail price difference between premium gasoline and regular gasoline doubled, from approximately $...
This section examines the possible causes for the increasing premium–to–regular price spread related to the production of motor gasoline and its components at refineries in the United States. To that end, EIA retained Baker & O’Brien to analyze the factors and conditions at refineries that could result in the increasing spread. Baker & O’Brien’s an...
In Phase 2, Baker & O’Brien analyzed whether or not the U.S. domestic refining industry would be capable of meeting higher octane demand if the octane requirements for retail gasoline increased. The scenario assumes that, beginning with model year 2023, all light–duty vehicles in the United States will require a minimum 95 research octane number (R...
3 days ago · \(\text{CPT}\) is the cost per ton (\$/ton), \(C\) is the total cost of the material (\$), \(W\) is the weight of the material (lbs). Example Calculation. For instance, if the total cost of material is $500 and the weight is 4000 lbs, the cost per ton would be calculated as: \[ \text{CPT} = \frac{500}{4000/2000} = \frac{500}{2} = 250 ...
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).
