Not sure which Sector airfield these were assigned to but as all the sector airfields had 100 octane fuel, these to would need a stock of 100 octane fuel.
RAF Detling
RAF Eastchurch
RAF Hendon
RAF Lympne
In 10 Group, 5 of the 6 airfields had stocks of 100 octane fuel.
In 12 Group, 7 of the 8 airfields had stocks of 100 octane fuel.
In 13 Group, 7 of the 10 airfields had stocks of 100 octane fuel. Of the 3 that possible didn't have stocks of 100 octane fuel, one was based in the Shetland Is. and the other in the Orkney Is.
Despite what the doubters say, I would say 100 octane fuel was in widespread use by Fighter Command if all those airfields had stocks of 100 octane fuel on hand during the battle.
