Here it is and yes it is CK-4 rated.

TBN is irrelevant. Thank you for sharing and the expenditure.

Yeah, I have no issues using this oil; already ran it in focus without issue.

Thank you very much sir.
It’s in my 6.7 Cummins at the moment.

Maybe @fantastic can copy it to the data base ?

That TBN 5.6 is a lot lower than what E/M has on their PDS. They show the TBN at 12. Maybe they are using something else that can’t be picked up on a VOA ?

Its much more important to monitor TAN and oxidation, @wwillson has published several used oil analysis demonstrating its importance for extended OCIs.

I’m not concerned about it since I don’t do anywhere near extended drain intervals. I just thought it was odd the difference in what the VOA showed and what E/M list in their PDS. It has taken me more than 6 months to put 3k miles on my truck but it gets a little more frequent use in warmer weather.

My thanks again to 53’ Stude for his efforts and expense.

re welcome. Now if someone would man up and do VOA on Delvac 10w30

TBN is probably low due to the lab using the ASTM method meant for used oils, instead of the method meant for virgin oils. An oil with this much Ca, Mg, B, will not have a low TBN.

Added to the list Adam. This is a very common oil that should give folks a good idea on what it looks like new. Thanks for testing!

Currently have this exact oil in my 1025R with about a year and 40 hours on it. Will be changing in about a month for the year.

Justin, I’ll be doing a DELVAC 10w30 VOA since no one can show me a VOA.

Compared to Rotella T6 15w40 on a Universal M25 diesel engine (Catalina sailboat)? Been advised the 15W is preferable to the 5W for this engine. Only operates May through October in Michigan.

Surprised to see the P & Zn that high as it is not advertised to meet the Ford Diesel specification for Powerstrokes.

@53' Stude
It does look a little weakened compared to the VOA I did on it in 2019.

I agree

Was the one you did CJ4 or CK4 ?

CK-4
I still have some of the ole containers.
Send me your email and I'll attach the OAI voa report like I did for @53' Stude .
