Thank you. When did this alleged switch over to 100 octane happened, dear David? With documentary evidence if possible.

However there is no evidence that 87 octane was used for combat missions after the switchover during the BOB from July onwards.

Of course, since it was standard fuel in the RAF. Similarly, there's no evidence that 100 octane fuel was used in more than a a couple of dozen cases out of thousands of fighter sorties, right David?


Let's get back to that allaged switchover, now you have seem to have changed your position and now state that this was supposed to have happened in July 1940. What documentary evidence can you offer to this so-called switchover, David?

Now if you or Crumpp can supply any evidence that says 87 octane was used in operational missions in or after July 1940 a lot of people would be very interested.

Again, we need to specify the type of evidence required. Should combat reports that do not mention the use of emergency boost or +12 lbs/sq.inch constitute such an evidence, David?
