CJ-4 Valvoline 15w40 Virgin sample

[1nighttrain]

Blackstone lab: we found nothing unusual in this sample,Molybdenum, an anti-wear additive, is used in moderation and without Boron. Magnesium is used in place of high calcium amount. The anti-wear properties are routine. We think this oil will serve your diesel engine needs well. What does every one else think ?

• 
  Moly 44

• 
  sodium 3

• 
  calcium 1182

• 
  magnesium 939

• 
  phosphorus 1019

• 
  zinc 1291

sorry i didn't add the viscosity @ 210'f it's 76.8 and the flashpoint is 425 and i didnt get the tbn ,

 

[BillionPa]

TBN should be 12+ considering the massive dose of magnesium.

moly levels are appropriate for diesel oil. too bad they didnt load it up with boron.

as per Valvoline the TBN is 10 i was trying to see what the difference was between the Valvoline PB 15w40 and the new Rotella 15w40 both are CJ-4 oils. the Rotella was checked here and it had a TBN of 10.3 but, both oils have very different add packages what would you all use between the two ? the PB 15w40 is on sale at the local flying-Js buy one get one free

The Rotella has done good in my old Pete. I like it. But I would run the PB if the price was right.

I was happy w/ my UOA of Rotella T CJ-4. Started at 10.3 TBN, 7400 miles later, TBN was still 8.2!
