[Healeys] Dave Dougan's overdrive part 2

[Oudesluys]

The idea of stick to what your manual says makes reasonable sense, 
although one must not forget that these recommendations are from the 
50's and 60's of the previous century. A lot has happened since in the 
devellopment of lubricants  and there are often far better alternatives 
available now. Problem is that they have not always been tested in our 
applications.
