Soviet aviation fuel: More bang for the buck or the ruble?
Can any members help with a query on Russian aviation fuel?
I understand there were five kinds based upon octane ratings; B-100, B-95, B-89, B-78, B-70. I suspect that little B-100 or B-95 reached fighter units and most used B-89. I assume B-78 was used by bombers and twin-engined transports while B-70 was used by trainers and the U-2/Po-2 but if anyone has more detailed information I would welcome clarification.
I have been informed this octane rating, and that of the German B4, C4 and what-ever fuel was used for trainers, was based upon the Motor Octane Number (MON) while the Allies used a higher rating based upon the Research Octane Number (RON).
Can anyone confirm this and provide the RON for Russian and German fuels?
