Multi-viscosity oils are labeled by what "curve" they would be on at two different temperatures, 0C and 100C. A 5W-40 is just saying that the oil behaves "like a 5" at low temps and "like a 40" at high temps. So, like others mentioned, to find the viscosity of your 5W-40 oil at 0C, you look up the curve for a straight SAE 5 oil and find the value at 0C. To find the viscosity of your 5W-40 at 100C (nominal operating temperature), you do the same thing but you pull the graph of SAE 40 and look at the viscosity at 100C. Now, that is a two point characterization, so there are some differences between those points comparing a 0W-40 and 5W-40 if you graphed both on a viscosity vs temperature plot. The difference is largely academic, though. |

Just did my oil change last weekend and used
So far so good. It might be me but the motor does sound a tad bit quieter after the oil change. FYI: I also bought a billet ECS oil filter housing to replace the plastic OEM one and do not recommend it. The new batch they have, the brackets inside are not cut correctly and the bypass valve is super loose you can jiggle it and it rattles and falls out when removing the filter from it. |

Correct. ECS sell 7 liters in a oil change set with Mann filter and magnetic drain plug at a decent price. Just be careful when adding the last half liter. Add a little at a time and check your oil levels so as not to over fill. I didn't quite use the full .5 liters on my oil change

FWIW - I do not like not having a dipstick so I can actually sample the oil at will and see/feel it. That sucks. I'm going to change every 5K miles, and I'm going with 5W-30. What about Mobil 1? There must be some reason why nobody's talking about using Mobil 1. This being the first car I've had with turbos, I'm guessing it has something to do with that. I've always used Mobil 1 on all other of my vehicles with absolutely no issues so I'm a fan.

Yes, I think highly of Mobil 1 but there are so many good choices that ARE LL-01 approved that I just prefer to put the approved stuff in my car. Also, Mobil 1 should get on board. All of these other companies do the work to get approved by BMW and the are not some small boutique oil brand. I still use Pennzoil Euro Platinum because it is Shell Oil just like BMW oil made from natural gas where other oils use different bases.
