I switch from Liqui Moly to this, Pennzoil is the actual BMW factory OEM oil, I use 5W-40, because more viscosity = less engine wear, at the cost of a bit of mpg, which I'm ok with.

The clean and fresh kind.
Liqui Moly is a trusted brand, I just go with OEM but may soon make the switch to Molygen to help pinpoint any leaks as my car ages. BMW used Castrol as OE until 2015 where they switched to Penzoil.

I'm not sure one gains a whole lot running say 5W40 vs 5W30. One might in fact gain more by running a zero weigh viscosity. I run 0W40 (I'm in warm climate) in my X3; normally aspirated I-6 motor. But I presume recommended viscosity is perhaps different for turbo charged engines. |

You guys think too much about oil. BMW specify the specifications to use on there car. Any oil that pass BMW is good to use. You can get the cheapest or the expensive oil.
For the weight, you can check under the hood for the recommended oil weight. The only time I will ever change weight is the application (car) use has change ie you going to track the car, you going to move and start living on a cold climate place or vise versa. |

Modern synthetic oils are so good in terms of lubrication/longevity that one can't hardly go wrong here |

I prefer a 5w-40. I was using the same Pennzoil Zanity has listed above, recently switched to MolyGen. Whatever BMW recommends will work just fine. I just sent a sample of the Pennzoil to Blackstone for analysis, will be interesting to see what the results were.

BMW TwinPower Turbo 5W-30 LL-01. I am in Europe so I use LL-04. Price for genuine in USA is so cheap, no reason not to use it.

A technician told me he heard a rumor that BMW was trying to reduce Valvtronic and other issues by going to 0w30 (LL01FE). The vast majority of BMWs sold in the US are leased commuters (stop-n-go, low speed). We now have ULSG but it's not as consistent as it is in EU so we'll probably never get LL04/LL12 OK'd to use.

If you start your car in the cold with a thicker oil that = more engine wear If you use a thicker oil not designed for your engines clearances (clearances between the crank/connecting rod bearings) = more wear Just use what's recommended. Going from 0w-40 to 5w-40 is nothing drastic and completely safe in a hot climate, but would not advise in a cold climate. |

I think you’re reading too much into the winter ratings. Even a 10W rated oil will flow at 20 below. As long as you’re using an oil that falls within manufacturers specs, you’re fine. The main thing to look out for with the heavier/thicker oils is not to go with so something so thick that it can’t readily flow at a sufficient rate through oil galleys throughout the engine, starving areas of lubrication.

I literally said 5w-30/40 doesn't make a difference but your statement thicker = more protection is simply not true You sound like you don't know what clearances are and how an engine operates to produce oil pressure.

I'm busy at the moment, this is all im going to say right now, my local area reaches over 33 degrees C outside in the summer, and only drops to -10 C in the coldest winter, so tell me how the lower viscosity 5W30 is better than 5W40 for my car? Heres a basic chart i quickly pulled, note the operating ambient temperature range but seriously, google and do some learning.
I quote:" 5W40 is a motor oil that penetrates to the active mechanisms faster, and provides excellent lubrication on start up. The number "40" implies that it differentiates from the most common motor oil (30) among the cars, as it is denser, and this ensures more profound engine lubrication during hot temperatures."
