I had one of these on an engine I bought second hand that had gear oil in it and had so much drag in it the gearbox couldnt be turned over in neutral when disconnected from the engine.

From this I surmised that it took engine oil. If you find out for sure could you please post that info.
Thanks.

Acording to my manual on the BMC Vedette, the gearbox uses 20/30 standard engine oil, the reduction box uses 140.
