I just reviewed the Valvolene Premium Blue Thread, and concur that very few Napa stores have any more of that oil in the CI-4+ formulation.
HOWEVER (no, not shouting, just for emphasis) I noticed that there is now a new oil. It is Valvolene Premium Blue Extreme. It is a 100% synthetic (at only $35 bucks a gallon !) and is 5W40. It IS rated for CI-4+ and does not have the CJ-4 symbol. It also has the Cummins Recommended symbol (The Cummins C) on the label.
I am wondering if anyone has had any experience using this oil?
