AudiJunkie - thoughts on Redline 5w-40?
All 5ws are not the same. All are tested at-25f, but higher visc grades allow thicker visc limits at that temp. That is 5w-30 is thinner than 5w-40. 0w-40 vs 5w-30, my money is on 5w-30 to be thinner and a good choice in some climates, even ours if wear stays low, and I think it will.
