I know this will spark a great debate, but it's winter here in Ontario and I'm about to do the first service on the Old Goat since buying her. Guy was running Q-state 15-40 since new, but I'd like to run full Synthetic for the winter. Canadian Tire has Rotella TSB 0W40 Full Synthetic on sale, but is 0W-40 gonna be ok for the old girl ? I've been using Rotella XLA 15-40 in my 6. 2 Chev for 300,000 km, and my father in law has 850,000 miles on his Detroit 550 Series 60 in his Pete, nothing but Rotella... . so I'm kinda sold on Shell.....
but is the 0W too thin even in the winter weather ?... . if so, I'll go to something else, not worth taking a chance.
My local Napa store sells WIX, so I'll use their filters.....
