Shimmed my oil pump.. went from 35psi to 45-46 psi..

[T680]

First time using the sta lube 85-90 with rotella 15-40, went from home to Chicago , but I've seen higher oil pressure ((46-47 psi)) with .80 c treatment at running temp than Walmart's gear oil with fresh oil and doesn't smell as bad ...

Btwy just changed the rears oil and I have 2.5gal delo syn-gear 75-90 leftover
Was thinking on using over the winter either10-30 or 5-40 engine oil and adding 1/2 gal of that leftover in it
Would it work????
