Funny, I remember telling you that on my 2.5L I ran nothing but 20w-50 in AZ in the summer and 10-w40 in the winter and you thought that was too thick. I still run 10-40 in texas right now, or did when I left
Why the change of heart from 0w-30?
I always felt the thicker oil was better protection against spun bearings and was worth the trade-off of any frictional losses.
