BlackSix,

Thank you very much for your reply regarding 100 Octane fuel. The aircraft instruments appear not to show 100 Octane performance;100 Octane fuel is documented as one of the fundamental aspects of the Battle of Britain for the RAF.
May I refer you to the detailed post from "Klem", dated 11th Jan, on the forum thread for requested improvements:

100 Octane fuel

--------------------------------------------------------------------------------

Type of improvement:
Add 100 octane fuel modelling for all Spitfires and Hurricanes.

Explanation of Proposals:
100 octane fuel was in use by all of the Fighter Commans stations by the time of the BoB. Geoffrey Lloyd, British Minister of Fuel and Power said; “I think that without 100 octane we should not have won the Battle of Britain. But we had 100 octane.”

A list of reports on another forum which I link to to save space (especially read "Appendix IV" for performance figures and the BATTLE OF BRITAIN section under "A. R. Ogston, excerpt from History of Aircraft Lubricants (Society of Automotive Engineers, Inc. Warrendale, PA USA), p. 12." for confirmation that "March 1940 Fighter Command converted all its Spitfire and Hurricane Rolls-Royce Merlin powered fighters to 100 octane"):-

and another listing combat reports mentioning 100 octane or +12lbs boost all from as early as May 1940

Benefits:
Historical accuracy/Realism.
