Hi wce
Some of the really heavy duty Japanese engines came with the separate oil sump - supplying the highly loaded bottom bearing with a constant oil bath. Change as per 4st, think its about 150ml of SAE30. Yamaha did this as well
You are probably right about south africa
So it's complimentary to the oil already coming via the fuel?
The 2 stroke oil must be left to oil the less stressed components like the piston and it's pivot points.
I wonder does the 2 stroke oil end up in the oil sump and mixing with the oil in there?
It must use a very lean ratio in the fuel.
