Before using 100 octan fuel MErlin III used +6 1/2 lbs maximum boost ( 1/2 hour limit) without any emergency power.

Dunno what data and information 1C gots for these early SPits.
The official Royal Air Force History states:

All benefited from the replacement of 87 octane petrol with 100 octane, which allowed the engines to run at higher boost, and increased the Spitfire's speed by 25 mph (40 km/h) at sea level and by 34 mph (55 km/h) at 10,000 feet.

Why would Oleg do anything different?
