Mobil 1 0w-40 vs German castrol 0w-40 vs rotella?

[GMorg]

So, there is no open flame in the cylinders?

It does seem reasonable that a higher flash point oil would burn off less oil high on the wet cylinder wall. Not much diff between M1 and Castrol on this, slim anyway.

Shell Rotella T6 5W-40 No gas certifications
Saps 1.0
Tbn 9.9
Flash 410
Noack 12.8%
Hths 4
VI 170

Castrol Edge 0W-40 ACEA A3/B4, API SN, VW 502/505, LL01, A40, 229.5
Information tough to find since Castrol hasn't published a lot of the official numbers
Saps > 1.0
Tbn > 10
Flash > 392
Noack < 13%
Hths 3.5
VI 169

Mobil 1 0W-40 ACEA A3/B3, A3/B4, API SN, VW 502/505, LL01, A40, 229.5
Saps 1.3
Tbn 11.8
Flash 446
Noack 8.9 (via blackstone voa)
Hths 3.8
VI 185


NOACK via backstone VOA?
Really?
Can't say that I've ever seen NOACK numbers in any Blackstone oil analysis.
Maybe via top of someone's head?


I have a spreadsheet I've been compiling the last few months. That was the note I wrote in the spreadsheet some time ago. I'll see if I can hunt down that report.

It probably looks something like this:

That Blackstone note was a mistake. My note said, "From non-mobil 1 source." I shouldn't have said Blackstone because I didn't attribute the source and I can't edit that original post.
