Maybe, or it could be old packaging. I was just at AA, and all of the M1 0W40 on the shelves was SN rated (shows approval as SN, SM, SL). I doubt they would be making all of the versions at the same time.

I still can't make up my Mind on what oil to get. This is a lot harder of a choice then I thought! I change my oil every 3k( I know not required but I do my own oil changes for the most part so it's minimal cost) just cause I have OCD. Let me know about what your guys opinions are when you make a jump to a new oil it be much appreciated.

OEM BMW Engine Oil
Random question. I purchased the BMW Genuine Oil SAE 5W-30 synthetic from ECS and was expecting to see "LL-01" somewhere on the back of the bottle. While this is the correct, recommended engine oil for my car, all it states on the label is "ACEA A3/B3".
Is this A3/B3 designation basically the same as LL-01? I'm just confused as to why the OEM BMW bottle doesn't specifically state that it's LL-01. Hope that makes sense. TIA!

That works out to $6.50/L, which is $42.25 per oil change, plus $9.00 for the filter. And I would rather use a full synthetic. |

Full synthetic is not the point. Your BMW requires LL-01 approved synthetic oil. The LL-01 requirements are very stringent and way beyond standard US oil requirements (API SN, SM, SL etc.). LL-01 has a minimum HTHS value of 3.5, minimum TBN value, etc. The Mobil 1 5W-30 you are using does not meet the HTHS requirements as specified by the LL-01 approval (3.1 vs 3.5 min) for one thing. Not all synthetic oils are created equal.

I should also add, that US law does not require oils that are marketed as full synthetic to actually be fully synthetic oils (Group IV/V base), but they can use Group III oils in their synthetic blends. This was based on a lawsuit between Mobil 1 and Castrol (which Mobil 1 lost, thereby opening the door for Grp III oils to be used in synthetic oils marketed to the public in the US).
Of course Group III oils are pretty high quality now, so really the quality of a synthetic oil should be determined by its tech sheet (HTHS, NOACK, pour point, VI, etc.) and OEM approvals (LL-01, Dexos, MB 229, etc.) and UOA in your car. Mobil 1 0W-40 is probably THE BEST oil they make, and it has Group III in it... Last edited by Iron Man; 12-03-2013 at 01:38 PM.. |

0-40 means it is like 0 weight oil at low temperatures and 40 weight oil at high temperatures.
5W 30 means like 5W at low temperatures and 30W at high temperatures. If you use 5W 30 where 0-40W is recommended you use an oil that is thicker at low temperatures which means it takes longer to establish lubrication on a cold start and thinner when the car is fully warmed up. Neither difference is a good thing.

Reviving this thread because my indy shop told me they use Motul oil when doing fluid changes. I then started researching the brand and it seems to be a top oil.
I'm just afraid that changing from the BMW approved oil I have been using for 91K miles will adversely effect the car. I had heard years ago that changing brands can sometimes cause gasket leaks,,.. etc. maybe I'm being paranoid. But, this shop can't say enough about Motul being a very good oil. It has some anti-friction properties "ester" that can slightly increase HP and add to the longevity of the engine. Is my engine too broken in to use this high tech oil? any thoughts?

Plenty of members use Motul without issue. As long as the oil is LL-01 approved your alright. I change mine every 5k so I just stick to BMWs oil, since others have stated the oil has plenty of life left at only 5k of use.

Thanks Zombie for the info.
I change my oil every 6,000 miles. Would using Motul be overkill or doesn't it matter as long as it has the proper rating.
