To be honest 100 octane never seemed to get an official DTD number (unless you can lay your hands on a source)

But considering 100 octane was in use by civil operators in Britain before 1939...even found an article from 1937 discussing the use of diesel engines to replace 100 octane burning petrol engines, and by 1940 there were already plans on making fuels of more than 100 octane widely available then yes common sense would dictate that by the outbreak of war 87 octane was already relegated to secondary use while being phased out.

heres some stuff I found while researching, just thought some was interesting reading.

Couple more..

p.s. ignore the second image, it has no relevance, I attached it by mistake.

[Crumpp]

besides wasn't 100 octane DTD 224?

LOL, NO, that was 77 Octane fuel, the fuel that DTD 230 replaced.

Yes it was....

It actually was available pretty early. Problem was there was not way to make it in quantity or economically.

It was about 2 dollars a gallon in 1939 while 87 Octane was ~.15 cents a gallon.

How Much things cost in 1939
Average Cost of new house $3,800.00
Average wages per year $1,730.00
Cost of a gallon of Gas 10 cents
Average Cost for house rent $28.00 per month
A loaf of Bread 8 cents
A LB of Hamburger Meat 14 cents
Average Price for new car $700.00
Toaster $16.00

Yeah.....I eventually saw that, question is still can anyone find the oficial DTD number for 100 octane?

Irrelevant, there is pretty much no upper price limit in times of war...hence why Britain was 'broke' by the end of war.

[Crumpp]

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.

[bongodriver]

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,

Britain was 'broke' by 1941, that's why L-L came into existence in the first place. The British could no longer pay the US supplies.

Fuel costs were a factor, reading the papers show that the British were quite aware and sensitive of the costs. Bomber Command's request for uniform supply of stations with 100 octane was turned down, even at the cost of a rather awkward system with both 87 and 100 octane stocks at these stations.

The British got their fuel supplies from the market, and had limited amount of cash. Try doing some shopping without money.. things don't come free, even in war.
