Your source, if I remember from way back in the thread, is a 3rd-party book. I asked if they had references since this is not a primary source and you ducked the question.

I didn't duck it. We have a source that states that RAFFC went completely to 100 octane, and there is no source that states that this is incorrect, and there is a large body of evidence that supports the view that RAFFC used 100% 100 octane fuel operationally during the BofB. If you don't accept the above source, than present some evidence that from July 10 to October 30 1940, that even a single RAFFC Merlin powered squadron was using 87 octane during combat operations.

There was about 46 RAFFC Merlins engined fighter squadrons available on July 08 1940. Surely you can find evidence that one of them was using 87 octane operationally during the battle. Just one...
