I guess I am trying to find out the best dino HD oil and people sure seem to like delo. Mystik is good stuff too I'm sure.
I am saying that from what I saw, including industry-relevant performance tests, not relevant to your engine, Delo 400 LE outperformed Shell, Mobil, 76, Philips (IIRC), Petro Canada, and a few others, which I do not recall).
Now, in my MB diesels, I found a MPG decrease using Delo 400, and better running/MPG using rotella T. In my BMW, it seems that rotella Syn gives better startup behavior (in terms of noise) than Schaeffer's 9000!
You cannot go wrong with any. There may be aspects of the various chemistries that you want to buy to, but none of these oils are going to be lousy... You may have to discern the rest from UOA.
Delo may not have enough Zn for your application. i do not know. Does RTS? perhaps, maybe not.
I have seen data that indicates that the latest formulations of Delo 400 really perform well. Beyond that, I cannot say anything. Unfortunately, UOA has to pave the way much beyond that. I'd suggest taking a look at UOAs and VOAs for some of the insight that you may want.
