My engine is so close to it's first start - waiting on 6 new shims which I hope will arrive this week. So: This morning I went over to my Auto-shop and got new plugs, 2 oil filters, a jug of coolant and a couple of jugs of Shell Rotella 10/30. Guy says something like: "You've been using 20/50 haven't you"? "Ya, but going lighter now." "Good thing", he says. "We can't get 20/50 and might not 'till Spring".
Apparently, Shell is having issues with product component availability and they (Shell rep.) doesn't know when 20/50 will be back on the shelves.
I guess it's was a good time to rebuild and switch to the light weight !
Maybe I should stock-up on my "Glen."
