Want to read this but the link is not downloading... "server not found". Did anyone manage to get a copy downloaded? I have an '06 Toyota Land Cruiser. The PO took it to Jiffy and they changed the oil in the 3 differentials (good) but they used 80W-90 Mobillube HD Plus Gear Lube (dino). That's...

I got a dealer oil change on my car in late January and I saw someone at the parts counter buying a few oil bottles. They appeared to be the new blue bottles. Makes me wonder which one (Castrol or Shell) they put in my car..? I have one of the N54 "real" twin-turbo engines in my 335i. My car...

I have been wondering this myself. I just had my last BMW dealer oil change, and the technician put the following part number for the oil: 83 21 2 405 085 this seems to still be the old 5W-30. It would be good if we got something better suited to these hot running N engines, like a xW-40, but I...

Reviving the thread... I tried the Lubro-Moly MoS2 in my BMW E39 528i with M52TU engine (2.8L I6). Same engine, same driving style and conditions. UOA results showed the following: Sample 1: Mobil 1 0W-40, 4068 mi Sample 2: Mobil 1 15W-50, 3800 mi + 1 300ml bottle Lubro-Moly MoS2 Moly...

Looking at the VOA's that have been posted here, I've noticed that M1 0W-40 has some Molybdenum, whereas GC 0W-30 does not have Mo, but has slightly higher levels of Zn/P. Looking at the VOA's for the BMW 5W-30 OE oil, it has a significant amount of Mo, around 100 ppm. Apparently Mo makes up...
