Blackdog, you and others, can do your 'what ifs' (I have nothing against them and would be intersting) but the fact is 100 octane was NOT in short supply. Even before the BoB started 8800 tons of 100 fuel was issued in May, 5700 tons in June and 8700 tons in July. Do you know how many gallons that is? (for rough calculation, 300gal per ton or enough to fill the tanks of 3 squadrons of Spitfires per ton)

No clear no consensus on what was historically correct? Open your eyes and mind as proofs have been shown. The only negative voices are those that want to castrate the RAF fighters and these voices have been crying the same tune for years.
Yes klem and even back in the day on the Ubi Il-2 board as well.
What is interesting is the main protagonist, who is in denial of the widespread use of 100 fuel during the BoB, put forward very minimal proof for 1.98ata boosted Bf109K-4s. This was only an own typed order, not an original document, which has been modified over time.
