Jbell, I'm sure you know Redline is located in CA, so is Chevron.
If you wanted to support a local small business, go with Redline. Chevron also has several oils that would work well, but they are far from a small busines...
It is not under warranty so no need for approved oil?
Except for the fact that engine is build by MB, and one might think they know what kind of oil should go in engine, that again, they build, why would OP go with anything else since M1 is $26 for 5qt and is much, much better then HDEO's or Kendall or whatever?
Like I said in many posts, obtaining approval is very cheap, so why RL does not do it? Amsoil actually did it for some of their oils. They could fallow their example.
I actually like their numbers in pds sheet.
If they approve 5W30 Euro (their low-saps version) I would be first to put it in my BMW. Until then, will get M1 5W30 ESP that is actually approved.
Approval locks you into making no changes for 2 or 3 years, however long the approval is for. I also suspect Redline has too many additives for official approval.
The very fact that Doug Hillary has recommended Delvac 1 5w40 in some Porsche engines should indicate something...
Approval also means that people who build engine might know what is good for engine.
I have no doubt that RL is good oil. It has good base, good if not best NOACK, very good HTHS etc, BUT, I do not have guarantee that that oil will meet needs of EGR, DPF in my car or leave maybe excessive deposits in OP's car.
Maybe additives that RL uses are not good for OP's car. Do you know 100% that they are good? or that they are OK for new diesels with complicated emission systems? Or DI engines and carbon build up?
Approvals do not lock anyone into anything. RL, Amsoil etc. will do anyway good first 50K or whatever until car is under warranty. Thing is whether they will cause long term issues. I do not know what RL cooks in the kitchen, neither do you, but I do now that MB said that whatever Mobil1 cooked in their kitchen, meets their standards. And unlike you and me, they actually designed that engine.
We are talking about his petrol engine, there is no DPF, no EGR (other than internal EGR), and there is no issue of deposits if using a correct oil.
For 10 or 15 years now enough people have used non-approved oils (redline, amsoil, truck oils) in European engines, we'd know if there were issues.
