I was playing with the Lubrizol relative performance tool and saw that since Mobil claims it's 0w40 meets VW spec 503 01, the wear performance rating moves from an 8 out of 10 to a 10 out of 10.
I compared this to Castrol 0w40 and Pennzoil Ultra 5w40 and neither of these have specs that I can quantify would do the same.
Any opinions?
