Doubt it matters in the long run... I run 20w50 in all of my BMW's. But if you live in a very cold climate it might not be a good idea. In Texas we have no issues and I run it all year round. It eliminated my smoking at idle unless I leave it for 20 minutes idling... which is almost never. Oil also stays at mid level fairly consistently and only add a half quart every 2000 miles or so.
This is just a band-aid "fix"... more of a workaround really. Eventually I'll do the seals, timing cover, valve covers, and alternator gaskets to fix this problem once and for all. But so far this has bought me 11000 miles of use over the last 14 months with no ill effects.
I don't really anticipate any either... as I said I run 20w50 in all my older cars, usually Valvoline V1 20w50 to be specific.
