I disagree. Crumpp has made a definate statement that 100 Octane was in full use in May 1941, all I want is his evidence that says it was May 1941.

Crumpp is very keen on us supporting anything we say and I want to know what his evidence is for May 1941.

Consumption reports that say that 61,000 tons, 315 imp gallons per ton, 192,151,000 imp gallons of 100 Octane was consumed between June and end October 1940

So, where did 192,151,000 gallons of 100 Octane go if it was only consumed by a small number of RAF fighters and some Blenheims?

Interestingly stocks of 100 Octane had already become greater than "Other Grades" by June - NOT October, as Crumpp has surmised:

Crumpp obviously believes that he knows better than all those "amateur" aviation historians who have written about 100 Octane so how about Crumpp takes some time out to write a best seller on 100 Octane, based on his professional expertise, and leave all of us confounded by his brilliance? :cool:

'So, where did 192,151,000 gallons of 100 Octane go if it was only consumed by a small number of RAF fighters and some Blenheims?'

Perhaps all the aircrew were putting it in their MG sports cars and BSA motorcycles? Thats one helluva lot of trips to the pub. ;)

That's a question you, and not Crumpp need to answer, Jeff.

And since you can't aswer it, you offer us only petty personal remarks and hollow arrogance.

Our view is that it was used by FC and No 2 Group, that you know.

If you and Crumpp believe that the use of 100 Octane was restricted to the number of squadrons/bases that you believe then the onus is on you to say where it went.

I think you misunderstand. Crumpp asserts that a fraction of the force were using 100 octane, yet a lot of fuel was used. What used this fuel? Wither he is wrong in that only a small amount used it, or he has an explanation for the use of the fuel, though he hasn't come up with anything yet.

That's a good one NZtyphoon and shows that 100 octane was the predominant aviation fuel in stock in the UK throughout the Battle of Britain.

Here's my answer. It was burned in Merlin engines on the front line providing the edge needed to knock down the Hun. Prove it wasn't.

No, That's a question you, and Crumpp need to answer, Kurfurst.

And since you can't aswer it, you offer us only petty personal remarks and hollow arrogance.

Great post, thanks for sharing.

100 octane fuel the main fuel stocked during the BoB, slam dunk.
