I have it in my Mercedes E300 now. I chose the FDS version of Ravenol 5w-30 since it was MB Approval 229.6. Not cheap, like
$10.00 / Liter, but I'm very happy with it so far.
The engine is a TGDI 4 cyl and the Ravenol is largely PAO base (or so it says) therefore according to their website, very minimal VII are used.
After a short while running it, I can see a light gray coating developed on the surface of the Cam Lobes, which I am assuming is a result of the Tungsten Disulfide.
For what it's worth, I've also noticed an increase in fuel economy, and routinely see 40 mpg on the display, and average about 28 mpg on short trips here in Florida.
