Could you post the current approved oil list? Perhaps that would put this issue to bed. |

It is also intriguing to me why the newer "gold top" "extended performance" USA Mobil 1 5W-30 doesnt have approval. Maybe they are still testing it or just havent gotten around to adding it to the list ( which is maintained by BMW AG ) The older "normal top" one never got it, but it was given to the 0W-40 one. I will keep checking for updates on the list and posting them on the forum

Wow, I am having deja-vu here. there was a very similar argument a few years back on the E46 board about whether or not Mobil 5-30 can be used. I’ll search and see if I can dig up the thread. Basically Mobil 5-30 in the US is not approved for use in BMW motors. The manual is wrong. The European 5-30 is. In the US you have to use 0-40 from Mobil. If you go to the Mobil tech specs on the oil, you’ll see that the actual viscosity (not the 5-30 on the bottle) of the oil is not quite thick enough to meet the standards for BMW. Apparently there is a range of viscosity that is acceptable to have for an oil to be advertised as a certain rating. Mobil 1 5-30 in the US is on the low side of that range and the BMW (castrol) 5-30 is on the high side. Thus both are “5-30” but not exactly equal.
Moral of the story: If you run Mobil 5-30 here in the US will you destroy your motor? Probably not. But, for me I am not going to take the chance when 0-40 is the same price. While the car is under warranty, I’ll probably just use the BMW 5-30, though with all the talk of high temps in 335’s I may go with the TWS 10-60 (M car stuff). |

LL-01 oils were recommended in the owners manuals for the M54 motors in the E46 however the E90 doesn't use the M54. The LL-01 spec doesn't apply to the E90 here in the US. |

Capacity-controlled oil pump: double flow rate, precise control, substantially lower energy consumption. In accordance with the current oil pressure, the capacity-controlled oil pump accurately supplies the required quantity of oil during each operating condition. As the oil circulation parameters (pressure, quantity and temperature) react partly in opposite ways, conventional pumps, which increase their flow rate according to engine speed, are not suitable for the complex requirements of the new BMW R6. The whole dimension of the R6 project is aptly demonstrated by one single ancillary component. With the capacity-controlled oil pump BMW achieves two goals simultaneously: the amount of oil intake corresponds to the quantity required under each particular operating condition. The capacity-controlled oil pump does not require a bybass in order to re-divert excess flow (up to 80%). Thanks to the regulation of the actual requirement and the elimination of unnecessary output, the capacity-controlled oil pump consumes up to 2 kW less than conventional oil pumps. That is part of the reason an LL-01 and A3 rated oils are not needed or necessarily desirable. Damn guys,BMW used to spec 20W50 down to 15f. You gonna use that too? Thicker isn't always better especially in an engine as complex as the R6 N52. Maybe in a less complicated design like the new twin turbo 335i engine perhaps. |

BMW came up with the LL-04 secifications for the diesel engines with particulate filters, while keeping the formula close to LL-01 spec for the petrol engines.

All BMW dealerships are required to use LL-01 or where available LL-04 oils The pump has nothing to do with what oil is speced

Why wouldnt BMW reccomend their own labeld USA oil which is produced by Castrol for them ? May I ask where you are getting your info about it not being reccomended ? Maybe because the owners manual doesnt state it ? ( it doesnt state most service requirements ) EDIT: From a BMW NA Dealer bulletin: "it is mandatory to use BMW High Performance Synthetic Oil in 1999 model year and later BMW models, Castrol Formula RS SAE 10W-60 Synthetic Oil or Castrol TWS Motorsport SAE 10W-60 Synthetic Oil in M5 S62 models produced up to 3/00 and E46 M3, E36 M roadster and M coupe with S54 engines. Also recommended is the use of either BMW High Performance Synthetic Oil, BMW High Performance Mineral Oil or one of today's highly advanced brand name lubricating oils conforming to API classification SH or higher in 1998 and earlier BMW models."
