Tried that and got a lot of different answers. There is an overabundence of information there. That's preferable to not enough, but can be quite confusing. Since I broke a timing chain last August, and found scuffed bearings and varnish in the engine using an SM oil (M1 0W40, which is recommended by VW) for 50K leading up to that, I do want to change something. For now I'm thinking M1 5W40 TDT, maybe changing to GC for winter. I'll let oil analysis be my guide, and let others run SM until the jury reaches a verdict.
