I really don't understand the desperate need to deny that most, and probably all, fighter command aircraft were using 100 octane fuel during the BoB. There is more than enough evidence to show that the change to 100 had been authorised well before the BoB, there were more than enough stockpiles, the conversion process was simple enough by RAF servicing standards of the time and it was in widespread use from combat and Squadron reports.

It would have been ridiculous for the RAF, with all the stocks available, to have only transferred some units to 100. Why would they do that when they were at war and expecting invasion? The only delaying mechanism would have been the mechanical modification of engines which was simple enough and carried out during servicing. New engines were delivered already converted. It would have been more ridiculous to suggest it wasn't available to the units facing most of the fighting and not very sensible, with the rotation of Squadrons with their aircraft, not to organise the support of 100 octane for those aircraft while on rotation.

I suspect that some people either want to unhistorically 'castrate' the RAF as someone suggested or they are just Trolling.

Regarding Blackdog's ideas for missions, I have no problem with representing fuel shortages following bombing of production plants etc but that is a seperate issue. It never happened to the point that fuel bacame a problem but a 'what if' is fine by me, that's what missions are built for, it isn't all re-enactment.
