Decided to try Valvoline Premium Blue in the new truck and let me tell you it is hard to find around here. The guys down at NAPA just shook their heads, they had never heard of it. I guess nobody around here uses it in their tractors
They finally came up with some P B Extreme 5w40 full synthetic and I told them I couldn't use the synthetic, they said that that was the only P B their books showed. Well after three days I convinced them that Valvoline made a P B fossil oil and they found a part#, from there it was only a matter of a few hours untill I had 3 gal in my hand. If anyone is planning on using Premium Blue 15w40 fossil the part # at NAPA is 70509. This might save some of you some trouble.
Valvoline thinks alot of this oil as it's priced $2. 70/gal higher than Delo, Rotella, or Delvac.
