Fuel...87 octane or 100 ?

The Octane rating is dependent on the date and location. Most Hurricanes in southern England during the Battle of Britain used 100 octane fuel and Rotol propellers.
I do not know the dates or bases, some other knowledgeable person may be able to help you.

The CLOD engine does even look at Octane ! ... it has no knowledge of it.

It simply says If in this aeroplane then give +12Lbs Boost at max chat. Historically we know that +12Lbs Boost was only available to when using 100 octane fuel.

So if you like the only RAF aeroplanes that are capeable of +12Boost are:

Spitfire IIA (Because as default IRL it used 100 Octane Fuel)
Spit IA 100 Octane
Hurricane I 100 Oct

All others give you +6.25Lbs Boost max chat to simulate 87 Octane fuel.

Thanks guy's, very helpful info here. I have now settled on the SpitfireMKIIa and HurricaneMKIa 100 octane to introduce and a small group of flyers for online mission testing.
