Hi JtD.

Sorry, I've not found any operational use of 87 octane in Spitfires, Hurricanes and Defiants beyond spring 1940. There is quite a lot of documentation available on 100 octane use for Spitfires, Hurricanes and Defiants during the Battle of France, the Dunkirk evacuation and the Battle of Britain, however, to be found throughout this thread. The best I can offer is operational Lysanders and Battles using 87 octane during May 1940 - see links below. Sorry, but the Hurricanes were using 100 octane by then - also see links.
