Problem with AVGAS. The Russians do not have the technology to build refineries to to make anything better than 81 Octane and even that is rare. They cannot expand this... in the extra year they have. There new fighters though need octane ratings of 87 or better ( this was a major screw up that was known to the Russians who were bargaining on no world retaliation to there annex of part of poland and the invasion of Finland ). There capacity to increase production of AVGAS is directly related to when the embargo on there assets and purchasing ability is returned to them after being frozen back in 1939, the same as OTL. And No they cannot buy the technology from the German's. The Russians can move factories, build some infastructure in a year, but they cannot solve this problem without outside help. Now when they do get allied help the first thing in the short term that will be done as per OTL is sell them the secret of Lead additive. This will, along with the regular russian fuel production will help but the two new American refineries as per oTL will be needed.
