Thanks Capt.
I'll see if I can get the Service Kit in S Africa. It will probably say in the instructions how much filter oil spray should be applied.
All I wanted to know really is how much one has to cover the filter element with the filter spray? Inside and outside, and how thick? Or is it just a guess ?
