I disagree with this statement. A high volume oil pump is not a high pressure oil pump. The pressure regulating valve determines the oil pressure. It does not matter if it is high volume or not. If you have a 40 psi spring you get 40 psi. You can install a 60 psi spring and that will give you high pressure. I just replaced a 40 psi spring which was only giving me 28 psi at cruise. Proof is in the pudding as I have a high volume pump. > Mark, 15W40 might be a little too thick of an oil for the weather you are currently having.

I am using the Shell Rotella T per the highly recommendation of William Wynne. Over the last couple of weeks I have discussed temps and oil with William many times trying to determine why I was getting the low pressure and high oil; temps. The oil is designed for higher operating temps therefore providing more protection at our operating ranges. Ambient temps here are prime for this grade oil right now. This oil is what William is running in his Vairs. I will change grade as needed as temps dictate.
