Well its rather simple, I would have believed even with a blindfold one would easily get it. The standard fuel in the RAF was 87 octane, and from around March 1940 we have a British document saying that 100 octane fuel replaced it in select fighter stations. No, it doesn't say all, it specifically says: "the fighter stations concerned".

That seems crystal clear I am afraid.

And, despite literally years spent desperately by some to find something to the contrary, there's an utter inability to produce a primary source even hinting universal use; Spitfire manuals from the summer of 1940 still continue to mention both 87 and 100 octane ratings, the fuel consumption figures of the RAF clearly show that 2/3s of the avgas consumption was 87 octane, research in Australia found a paper that clearly noted RAF FC had not managed to fully convert until November 1940; the utmost Spitfire authorites has noted the fears of 100 octane supply due to tanker losses and the U-boot threats.

Most of us find it difficult to ignore all of that, unlike you. And just because you continue to use loud rhetorics in otherwise hollow and childish posts, its not gonna change.

Abundant evidence exists for hundred octane fuel use by RAF FC, during operational sorties, but none has ever been produced showing 87 octane use by a single front line BofB RAF FC Spitfire or Hurricane sortie.

Which part of 87 octane being the standard fuel in the RAF FC prior the spring of 1940 and that afterwards select fighter stations were receiving 100 octane fuel were you unable to decode?

Kurfurst, it is time for you to put up or shut up.

I don't take orders from you I am afraid.
