I am sure you can find all kinds of references to 100 Octane fuel in the 1930's.

Here is the Popular Science archives to help you out!

It was quite a leap forward in fuel technology and was greatly anticipated.

Help me how?.....I wasn't highlighting surprise at reference to 100 octane prior to 1939, it's practically common knowlege.

No the real surprise is that you 'still' insist 87 octane was the main fuel in use......has anyone asked you to produce a shred of 'evidence' yet?

Again,

Read the Operating Notes.....Spitfire Mk I, July 1940:

Not issued. Initially using a provisional specification R.D.E./F/100, later manuals refer to 87 octane, 100 octane or 150 octane fuels as such.

All aircraft fuel must be specified.

No mention of 87 octanes whatsoever.

Just the fact it is the specified fuel and the FC consumed millions of gallons of it.

Yes, but not in front line fighters.

Edit - ah, just noticed Crumpp is saying FC. No, not millions of gallons then.

There is data on 100 octane consumption by RAF FC but I don't see anything on consumption from those claiming 87 octane.

How much 87 octane fuel did RAF FC consume during the BoB?

Not referenced in aircraft and engine manuals, though. Because there was a variety of 100 octane fuels which could be used. Asking for THE specification of "100 octane" is like asking for THE flavour of "ice cream". There are plenty.

No it is not.

From the January 20, 1943 Edition of the P-47B, C, and D Pilot's Flight Operating Instructions:

All fuel is specified by convention and by convention is part of the airworthiness instructions for the design. The aircraft's publications will list the fuel by specification that is authorized.
