I agree with the manual, Tom. 20W50 Castrol is the one. If you buy 30W
you'll note "HD" or "ND" ( high detergent;non-detergent)after the weight
designate. You'll find that the 30W stuff will foam like hell in your
tranny for awhile, and it will cause even a good one to whine. My
advice...stick with the book.
