Back on this. I ran LM Special Tec 0w20 for the winter and it produced a very good UOA.
Thinking of making switch to 0w30, but spoke to someone much smarter on engines than I and he said the only issue with a higher weight/HTHS is the cam phasers/VVTi on these. Also want LSPI protection but most oils I’ve looked at seem to.
I would imagine 0w30, particularly in hot summer weather, wouldn’t be a massive step up in weight to be a problem with phasers.
Thoughts?
