This just started to recently be imported into the states from the Netherlands by Blauparts. I saw they're a huge sponsor for the Dakar race, so I figured I'd check it out. One thing I see is calcium seems high for it being marketed for mercedes vehicles using DI.

The high Phosphorous and Zinc numbers work well at quenching LSPI.
TBN of 9.5 is well within a 40 grade of oil.
The SAE grade designations have a TBN requirement?
I'm not claiming that. Just from my personal experience 9.5 TBN is not a "Low Number" for a 40 grade. Don't you agree?
No I still don't understand the connection. But I'm not one to get overly concerned about TBN these days with low-sulfur fuels.
I don't understand what you're implying here.
The question was "shouldn't that TBN be a bit higher for a 40 grade??? Or is it in line with it???"
My response was a TBN at 9.5 is considered a great number, including a 40 grade, & not out of line.
I'm not aware of any standard that states a TBN for a certain grade of oil. You are claiming that I said there was some sort of SAE connection between Grades & TBN's Which I've not said anywhere.
If you don't understand what was mentioned or that I'm implying something else then I don't know what else I can offer you.
Because you said:
Which implied some sort of connection between the TBN value and a grade. It is well within a 30-grade too, or a 50-grade or whatever.
Which implied some sort of connection between the TBN value and a grade. It is well within a 30-grade too, or a 50-grade or whatever.
You're right in the sense that it Sounded like a connection to you. That being said I didn't imply & don't have any connection for a TBN to Grade Value.
I will repeat it again b/c I think it's a fair statement. A 9.5 TBN is Not "Out of Line", Including a 40 weight, for this VOA.
I meant the same thing as your last statement but written a bit more direct since they were asking about this weight specifically. If I said there was some sort of min. requirement blah blah then perhaps you'd have an argument.
