If you had done a search on Oils, you'd find it more confusing than ever. The discussion and debate is full of passion, to the point that it knocks you out 2 to 1.
The conclusion I drew from this discussion, is to use semi-syn oils or regular for more mature MBs. But let us not be drawn into this until you have read the threads and perhaps, post your own opinions at the end of the relevant threads.
It would be nice to pick up where we left.
Once again, welcome!
