I'm curious if there are any other motor oils available other that the Castrol products sold by the dealerships for the new 3.0L diesel engine . Looks like Red Line Euro Series has the correct specs. I have used their reg synthetic oil in other BMW gas engines with success. Does anyone have any experience with this product in a recent model BMW diesel engine. Any other synthetic oils any one can suggest.
There are many LL-04 low saps oils available. You need to look for them a bit, and ensure that they have the LL-04 spec. Amsoil and Royal Purple have oils that they "claim" meet specs, but they don't pay for the actual acceptance. If the bottle doesn't have LL-04 on it, ensure that it's ACEA A3/B3-B4/C4 (the API specs - usually SM/CF - are laughably useless.) Pentosin is sold at O'Reilly's and is the easiest for me. Liqui Moly, Motul Specific and Quaker State make LL-04 products. Mobil 1 ESP Formula 5W-30, Pennzoil Platinum European Ultra Diesel SAE 5W-30, and Total Quartz INEO MC3 5W-30 are relatively easy to find - NAPA carries the Mobil 1 product, I believe. I'm sure that Shell makes a product - oh, yes, it's Shell Helix Ultra ECT 5W-30. Some people are using the Shell Rotella T6, which is actually for heavy-duty trucks.
