A report I read indicates that 100 octane fuel was not very much liked by the Allies. From the German side, enough Allied examples were recovered for use and while fuel was limited, it was available for test purposes. As you mention, 87 octane was common but toward the end of the war, the order was to fly missions when it was thought they could make a difference. With thousand bomber raids, sending up a squadron would not be practical.


A German report about 100 octane fuel indicates that spark plugs had to be changed regularly in Allied aircraft that used it. By that I mean more often than in aircraft that used a lower octane fuel.
