I've searched around forum,reddit and Google but I would love to hear some opinions on here for a 23' 501a
I have in my garage a 5 gallon bucket of Royal Purple 80w90 max gear. I know the book calls for 75w85 but would like some opinions if I should go for the swap or stick with the book. I also had a hard time finding if I need friction modifier or not.
Thank yall for any help.
