The main petroleum component used in blending avgas is alkylate, which is a mixture of various isooctanes. Some refineries also use reformate.All grades of avgas that meet CAN 2–3 [further explanation needed], 25-M82 [further explanation needed] have a density of 6.01 pounds per US gallon (720 g/L) at 15 °C (59 °F).
The use of the term paraffin in place of the standard chemical nomenclature alkane is particular to the oil industry (which relies extensively on jargon). The composition of a gasoline depends upon: the oil refinery that makes the gasoline, as not all refineries have the same set of processing units; the crude oil feed used by the refinery;

This computation accounts for the well-to-wall losses resulting from the extraction of crude oil and refinement into gasoline (T p), conversion to electricity (T g), and the transmission grid (T t); in summary, the total amount of useful electrical energy that can be extracted from gasoline is just 36.5% of its total theoretical stored energy.
