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.



A 20 weight IS too thick at start up.

Even a 10 weight has lower start up flow ability.


I never ran 0W30. I ran 5W30 Mobil 1.

Mobil 1 does not make a 5W40.



holy crap! 20W-50!!thats like molasses man!!!!
