That's an interesting claim. Can you tell me how much 100 octane was spent on operational training, engine testing, run-in, was used up by Bomber Command's Blenheims etc..? Without that, your calculation is an extremely crude and wishful example..

RAFFC had about 45 Merlin engined fighter squadrons and 5 Blenheim Squadrons operational under RAFFC command on July 08. About 10 - 12 Hurricane, non operational squadrons were forming up.

so lets say that RAFFC had 57 operational squadrons during the 1st week of Sept. 57 squadrons into 5700 sorties = 100 sorties week/squadron. Lets assume 15 Blenheim squadrons (5 x RAFFC and 10 X RAFBC) = 1500 sorties at 230 gallons/sortie = 1108 tons of 100 octane. So our 5 Blenheim squadrons flew 500 of RAFFC's sorties leaving 5200 to be flown by Merlin engined fighters @ 75 gallons/sortie = 1254 tons, so total RAFFC and RAFBC 100 octane use = 2362 tons. This is only about 1/2 the total consumption of 100 octane and it accounts for 5200 SE fighter and 1500 hundred twin engined Blenheim sorties. There simply isn't enough 100 octane fuel users left over to consume the ~4400 tons if RAFFC isn't using 100% 100 octane.

Its a tiny amount, even compared to 1940 overall or later RAF consumption.

According to the graph you supplied, the RAF used about 15000 tons of 100octane and ~ 24000 tons of other grade during Sept 1940. How much 100 octane did the Luftwaffe use?


Can you present evidence stating that even one operational RAFFC Merlin engined squadron was using 87 Octane from July to Oct 1940? If I was an RAFFC pilot and my Hurricane/Spitfire was using 87 octane, when the squadron down the road was using 100 octane, you can be sure that I would have mentioned it my memoirs or complained about it while writing up a combat report: "The Ju-88 got away because I couldn't use overboost..." Yet there isn't a single statement anywhere about RAFFC pilots complaining about the lack of 100 octane engines or fuel, during the Battle.

Can you present evidence that there's no giant pink elephant with white stripes and a huge "Nokia" advertisment tattood on its forehead hiding behind the other side of the moon?

There isn't a single statement about RAFFC pilots complaining about the lack of giant pink elephants with white stripes and a huge "Nokia" advertisment tattood on there forehead flying Spitfires during the Battle either.

Its shows very well that giant pink elephants with.... were well supplied to every FC Squadron during the Battle. I guess.

So the answer is no. You cannot present evidence showing that even a single operational squadron of merlin engined fighters was using 87 octane fuel during the battle.
