- An alternative is to replace part of this isoparaffinic cut, and at the same time reduce the proportion of alkylate, which is a petroleum base whose manufacturing cost is relatively high, with a cut of hydrocarbons from a unit. isomerization of light gasolines, the latter coming from the distillation of crude oil.
- the complement used (B3) is a cut of hydrocarbons containing 6 to 11 atoms, the content of aromatic compounds containing 6 to 9 carbon atoms is typically greater than or equal to 80% by volume, and preferably greater than or equal to 85 % in volume. Even more preferably, these aromatic compounds contain 7 carbon atoms and are toluene, the content of which in the complement (B3) is greater than or equal to 45% by volume, and preferably greater than or equal to 50% by volume.
- This base of hydrocarbons used in the formulation of gasoline for aircraft engines generally comes from a manufacturing process, called "reforming" of gasoline, available in particular, in an oil refinery.

- aromatic hydrocarbons are generally called "reformates" in the profession and have a high octane number.
- the fuel according to the invention can contain many other bases. These can be chosen in particular from all the bases likely to enter into the composition of the essences. These bases can come from conventional refining operations (for example, but not limited to, the distillation of crude oil, catalytic cracking, hydrocracking, reforming processes, isomerization, alkylation Certainly , but also include synthetic hydrocarbons such as those obtained by oligomerization of olefins or by Fischer-Tropsch synthesis.
- these additional bases are chosen from those having a distillation range of between 25 ° C and 175 ° C, (determined according to standard ASTM D 86) and even more preferably, between 75 ° C and 135 ° C.
