I'm not sure what you're getting at. I'm pointing out that certifying Delvac 1 ESP 5w-40 to a bunch of European gasoline specifications would cannibalize sales from their other varieties.
Delvac 1 ESP 5w-40 is a dual rated HDEO. It's specifications include SM, CJ-4, ACEA E7/E5, a bunch of North American diesel specifications, and for European manufacturers' specifications, all it has is MB 228.31 and 228.3 and Volvo VDS-4, VDS-3, and VDS-2. I'm assuming that the latter five are all diesel specifications.
The spec sheet is
here. I'm still unsure as to why you think such an oil would be absolutely unsuitable for a newer, albeit out of warranty, German turbocharged car. What qualities does it lack?
I remember that a certain esteemed member here went through the same nonsense with his choice of lubes in his premium German automobile. Everyone told him he didn't know what he was talking about, regardless of his credentials in the matter, nor a subsequent approval from the manufacturer in writing.
Again, aside from manufacturer approval (which I'm all for following, particularly under warranty or when one cannot make an informed choice), where is something like Delvac 1 ESP 5w-40 lacking?
Isn't easier form many points for Mobil to sell just one oil as their premium oil for all applications?
Does that mean that Shell Rotella T6 and PU 5W40 are same oils? Why not hten sell PU 5W40 as premium oil for all applications? They save money in marketing, several packages etc, etc.
I am not saying car will die tomorrow if you using Delvacor whatever, but car will run better with oil that meets specific requirements (consumption etc).
