You can't just make stuff up and attribute it to a historical figure. You don't really know what octane the pilots wished they had, did you?

The Germans generally didn't concern themselves with RO Numbers; their fuel was graded alphanumerically. C-3 fuel was what the Allies would have called 130 Octane fuel (150 after 1942 IIRC).

Fighter pilot don't give a damn about octane ratings except to get more power. One way to get more power (at least on the Merlin) is to run the engine on a higher octane fuel and increase the boost pressure. RAFFC did this to every Merlin powered fighter in its operational inventory, and thus no pilots are recorded as wanting 100 octane fuel, "like my pal has in the squadron done the road".

Luftwaffe pilots also pressed for "more powerful engines" and again high octane fuel made this a much easier proposition. Asking for more power is exactly the same as asking for higher octane fuel. ( I didn't have to wait long for the "we don't need no stinking 100 octane fuel" claims from the Lufters... )

Couldn't agree more.

Please quote where I said that.

Its not true. Moelders asked for a series of Me109's with more powerful engines. DB 601 A-1, DB 601 Aa, DB 601 N, later DB 601 E (for F), DB 605 engine family (for G-K). All were stronger than the previous type, without it that they would use the 100 octane C3 fuel instead of the 87 octane B4 ones. Of course, if they use C3 fuel, MW30, MW50, or GM1 system, the strength of the engine is growing rather yet. But purely visible, that it is possible to make stronger engine, using the same fuel (B4):
