Just put it in a 335i with the N55, single turbo engine that is being used across the current BMW line-up. It seems to work fine, can't say I feel any difference from the OEM Castrol 5W-30 that was in the car before. Which might be a good thing.
I always wonder...what does Castrol & Pennzoil Ultra do instead of using Moly? These are all great oils. How do they make up for not using Moly?
Boron, antimony, etc
This oil has no boron and I've never seen a major motor oil company use antimony. RLI uses or at least has used it. Given this, I'd put my money on ashless friction modifiers being used. Glycerol monooleate is an example.
