The cost of producing incremental octane was calculated using two approaches and was shown to be less than the market price of octane. Gasoline, gasoline components, and feedstocks (e.g. naphtha) used to make gasoline are global commodities that are frequently traded between regions and countries.

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.

In refining, marginal costs typically drive market prices • Catalytic Reforming units are the primary controllable octane source in the refinery • Refiners can optimize unit throughput and severity (octane of product) • Higher octane results in higher costs • Reformers convert naphtha feedstock into highoctane, high- -aromatics

The octane number of gasoline is one of the most important measures of gasoline quality to predict accurately the octane ratings of blending gasolines. This measured on a scale that ranges from that equivalent to isooctane (octane number of 100) to.
This calculator helps you determine the octane rating of a blended fuel mixture from two different fuel sources. Fill in the volumes and octane ratings of both fuels and hit the “Calculate” button to get the resulting octane rating of the mixture.

Octane Calculator. This calculator determines the minimum octane rating, also know as the knock index, by the formula (R+M)/2. Octane rating number is defined as a value used to indicate the resistance of a motor fuel to knock. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock).
