[s-cars] Synthetic oil weight rec's

[Wylie Bean]

One reason for my switch was consumption. Using Castrol GTX 20W-50 I was experiencing fairly heavy consumption.  I ended up going with M1 15W50 so we'll see how it goes this interval.

I had plenty of lifter tick using Syntec after a hard run on my 200 10VT.
The few times I tried autocrossing the 200 (not worth it, IMHO) the lifter
tick would take as much as 1/2 hour after a run to subside. There was still
lifter tick with M1 (closest weight as possible to the Castrol, M1 15W50 vs.
Syntec 10W-50), but it was much less severe and lasted for much shorter
periods. Since then quit using Syntec. No such problems using M1 in the S6,
although there has been more consumption (as in, there is some) using
15W50. I've had no consumption running M1 10W30.
