Aviation gasoline B 91 / 115 is a mixture of hydrocarbons prepared by the processing of crude oil. It contains anti-knock, anti-oxidant, dye and anti-static additives.
Aviation gasoline B 91 / 115 is specially designed for Shvetsov ASh-62 – nine-cylinder, air-cooled, radial aircraft engine produced in the Soviet Union. OBR PR is the only producer worldwide of this grade of gasoline.
GUARANTEED TECHNICAL PROPERTIES
Aviation gasoline B 91/115 is produced according to GOST 1012-72 aGeneral Aviation Fuelnd WT-06/OBRPR/PD/60.
Gasoline should be stored in containers that protect the fuel from air, moisture and mechanical impurities away from direct sunlight and heating (underground and above ground tanks with limited air exchange). These restrictions limit both the loss associated with evaporation and loss of the lightest elements, which may change the two key parameters of gasoline: vapour pressure and fractional composition. We work closely with our customers to ensure storage solutions are both suitable and safe.
