It meets/beats 0W-30 cold crank properties. You should be fine in the winter. And those heavy duty diesel trucks gotta start to get to work no matter what

So, BMW, VW/Audi/etc, created specs that require certain additives in the oil to fight carbon buildup. They don't prevent it, but they reduce it. So, I would suspect, the LL-01 was the first oil with those additives for gasoline engines, and LL-14 is the updated spec with lower overall friction for higher efficiency, and possibly new/different additives for the same purpose. The rest of this is just my experience, but it is informing my current choices: My last car was also direct injection, modified, and I didn't run a catch can. At about 60k miles, I was getting the intake manifold replaced under warranty and the dealer offered to walnut-blast the valves for cheap since everything was off. I had them take before/after pictures, and showed them to my tuner. My valves were WAY cleaner for a 60k tuned car without a catch can than most 30k tuned cars with catch cans.. most of whom run 'high performance' oils without the OEM approvals, while I ran fully OEM-approved oil with half-duration change intervals. I think the combination of using the OEM-approved oil, and reducing the change interval to ensure the additives didn't get used up, kept my valves way cleaner than if I had been using a 'high performance' oil without the OEM-specified additives. So, I won't run an oil that doesn't have the BMW spec on it (Well, I MAY be convinced to run an oil with an equivalent VW/Audi or Merc spec, but I'd have to do some research on BITOG or similar to see what may fit the bill..) but since I also don't feel the need to run a super-heavy oil, the OEM oils seem sufficient to me. I just don't let the car go the full duration between changes. (It is worth noting that the condition-based servicing alone lowers my change intervals from the quoted 10k, but I'm probably hovering around 5k-6k changes, on average, because I'm always at the dealership a couple k early and just get it done while it's there.) |

Really interesting test.
I've been changing mine every 5K. I use the Twin Power 0w 20 LL14+. After my first break in oil was out (1300 miles), I added a syringe of Tribotex. Not sure if it is snake oil. In theory nano particles sound like something out of a sci-fi thriller. I can see the argument to run a thicker oil on a tuned car, but I agree, not out of the OEM spec. |

Just for everyone not wanting to look at the manual but Xw-30 and Xw-40 are within spec.
(I run 5w-40 in the summer, 0w-40 in the winter in Michigan) |

I had to google that stuff.... DLC is real, but DLC is applied to surfaces using phase vapor deposition, I think DLC in your oil is not going to do much.

https://f30.bimmerpost.com/forums/sh...85&postcount=4 It looks like EU fuel contains lower levels of sulfur and thus the low level SAPS in the oil isn't a bad property. But over here in the US and other countries with high sulfur content gas, it's a no-go. Take all of this with a grain of salt, however. "BMW Longlife-04 (BMW LL-04) Special BMW approval for fully synthetic long-life oil. Viscosities are SAE 0W-30, 0W-40, 5W-30 and 5W-40. Usually required for BMWs equipped with a diesel particulate filter (DPF). Can also be used where a BMW Longlife-98 or BMW Longlife-01 oil is recommended." |

Im running Liqui Moly Molygen 5w40 and Mann oil filter. Will be changing my oil out in 2,000 miles and sending a sample to Blackstone labs. Will update this thread when I get my results back.

I gotta say I am really liking the Valvoline 5w40 diesel .. it's running mint. The idle is weird you can barely tell it is running and it is rev happy. I have posted here before about a rough idle .... 0w20

I was reading the link above and the only thing I read about using diesel motor oil in the B58 or any modern gas engine would be early failure of the catalytic converter. Anyone know anymore about this? I am still planning on using a 5w40 diesel oil like rotella t6 or maybe even Amazon basics 5w40 heavy duty diesel oil. |

Anyone have experience with LiquiMoly Special Tec 5w30? I always used the LiquiMoly leichtlauf in my old N54, but it looks like that only comes in 5w40 and I don't want to get that thick. Plus the Special Tec seems like a great deal right now on FCP. Would I be fine running this stuff in SoCal on a stage 2 tune?

Get whatever is the cheapest, full synthetic oil you can find that meets spec, and change oil at 5k intervals. 0W-30, 5W-30, 0W-40, 5W-40. |

The phosphorus and zinc is high, which are two elements that can cause damage to cats. https://sharena21.springcm.com/Publi...2-ac162d889bd1 Now saying this, I've yet to hear of a failed cat from diesel oil use. These are anecdotal and not scientific, but if you head over to read Rotella T6's reviews on Amazon, you'll find people that run it in everything from a 7.0 Cummins turbo-diesel, to a Kawasaki bike, to a Miata, and to a WRX. This scientific article says yes, it can harm cats: https://www.researchgate.net/publica...ne_dynamometer |

I just switched to Rotella T6 yesterday. When I drove my car, I noticed my exhaust smelled different. Im catless, and very familiar with the typical catless smell, but now it smells "dirty" for lack of a better word. Would that explain why it changed up?

As far as additive packages go though, I'd also be interested in the calcium/moly content nowadays given the prevalence of LSPI in newer engines. Maybe the B58 doesn't have issues with it, but given most OEMs tend to try to hold the taller gears at higher load/lower rpm under normal conditions, it may be worth at least talking about. Castrol used to be super low calcium, but my understanding is that it's crept upward in recent years.. |

Give it a few days. It's likely that you got oil on either your valve cover, cylinder head, turbo, etc. and it's just burning off.

That's what I thought too, but it seems like its coming from the exhaust. Didn't spill much if any. I'll give it a couple days and see what happens. I changed the spark plugs too, but don't see how that would matter. Car seems to like it tho so no problems there

Is the BMW branded Shell 0w-20 really not that good?
It seems like a great option to run in cold temperatures. The Liqui Moly rep in this video kind of gives away the game, I think: Oil now is more about just being a fluid to deposit additives on the engine parts, and less about the base oil actually lubricating bits. |
