Synthetic oil
The merits of synthetic v mineral oil is being disucussed on a forum and I've just read this:
As an old dragracer, we used the synthetics extensively, for everything. In fact Amsoil was/is widely used.
Our problem was drain-off, or cling. When the engines sat for any length of time, parts would end up completely dry. The bottom of the intakes would dry to the point of rust, as would rods, cyl walls, etc. So those of who didn't run weekly switched back to dino-oil, in light weights.
So, my view is that synthetic has big benefits for the folks who run almost everyday, and drawbacks for those who don't.

Can anyone shed light on this?
