A question, though. In motor vehicles it doesn't really matter if you put 89 or 91 (or even 94 like we can get locally in Ontario) octane gas in a vehicle rated for 87 octane. You're just wasting money on the higher octane gas since you'll see no performance benefit, but the higher octane won't damage your 87-rated engine. Would this apply to Merlin engines rated at 87 octane that received a fill up of 100 octane?

If there were no harm (or benefit) that would come of this, I could see at the start of the Battle of Britain some of the older Spits & Hurries receiving 100 octane out on the field.

The answer is also certainly yes, unless some extra complication occure - spark plugs may foul from deposits because the different chemical composition of different grade fuel, for example, as happened with 150 grade. But overall this seems unlikely, at least the papers I have show the Germans too were running some of their Ju 88s - which's engine was designed for 87 octane - on their own 100 octane fuel. So the practice for it was there, on both sides.
