I just received my VOA for my sample of John Deere Plus 50 oil from Blackstone Lab and was very surprised with the test results. I will also note at this time clearly marked on the container are the words "Synthetic base oils along with JD's unique additive system provides superior protection for diesel engines. It lists API CH-4,CG-4,CF-4,CF/SL,SJ,Allison C-4, and other engine manufacturers. The requirements for my Duramax engine are CH-4
Here are the numbers. Note all other numbers were zero for the other elements not listed here.
This oil is manufactured in Canada for John Deere&Company
Moly 49
Boron 73
Silicon 4
Sodium 1
Calcium 1707
Magnesium 6
Phosphorus 553
Zinc 615
Barium 1
SUS Visc @210F 75.3
Flashpoint 410
0W40 John Deere Plus50-Canada
What was very surprising to me was the following comment.
"This oil has a viscosity that would be normal for a 15W40,10W40,5W40, or 0W40 when measured @210F. But this is not a diesel-use oil. Diesel-use engine oils have zinc, the anti-wear component of the additive group, up to around 1200PPM. This is a gas engine -use oil and we would not suggest using it in your Duramax."
What I'm concerned with here is that I have a product clearly marked as made for diesel engines however it is lacking the required additive package according to Blackstone Lab.
Has anyone ever come across this with any of the other 0W40 brands of oil? Your comments would be appreciated.
