And your point about Mobil and Castrol and Shell is JUST like I've said before. So long as you're not WAYYY off on weights, and it's a good manufacturer, you're good. Shawn |

My car has almost never seen the dealer, and I'm out of warranty - so my options are whatever my heart desires . Give me a recommendation - I'd like to see what you purpose, thanks. I heard good things about total oils as well. |

Questions: 1. Do you track or drag race? 2. Will the car see freezing temps or greater than 105deg F sustained? (and be expected to start and run frequently) If you do neither, I'd stick with the Redline, it's fine. If you do either, I'd think about it before I said something stupid. But if you run around town, and don't really see high temps, or freezing, the liqui-moly recommendation from DannyD is AWESOME. That ALSO being said, people wonder why 5W-30 vs. 0W-30. The 0W-30 requires more "tricks" to be played to make the oil do THAT. It wears out quicker. Honestly. If we could REALLY make sure our cars only started at 75deg F or above all the time, and never ran stupid hot, we'd run a straight 30weight oil. Truthfully. But, we live in the real world. Where things aren't so easy. DannyD, this is why Liqui-Moly says 5W-30 over 0W-30. Less additives that wear out. Shawn |

I'm a big fan of 2 cans of LiquiMoly Mos2 additive with every 5k with every oil change as it adds protection for crank & rod bearings that cannot be had with oil alone. But just don't take my word for it, I brought receipts. Below is a video I just did testing a intake I made for my 10 year old X5 with the original 182k mile n63, the OG engine that started it all and what all S63's are based off of (they still share a few things like crank bearings).
Even after a brutal life with its previous owner, then I get a hold of it, tweaking, modding, and tuning it for the past 5 years to S63TU3 power levels despite its inferior stock turbos and cast pistons, and driving it like I stole it every single day, it still is as fast as new 2022 X5M. That is saying something on a 182k mile engine that pushes a 5300lb tank. Again highly recommend the MoS2, just check with your SA before using to make sure it wont mess with your warranty.

I've tried both ways. Can't tell a difference personally. But that's probably because I've done a lot of really good oils and not much garbage. I'm being lazy. What does Liqui-moly say? Shawn |

WHY NOT HAVE IT IN THE OIL ANYWAY? If it isn't in the oil that's BMW approved, there's a reason. They know it, and just get them to cop to it. My buddies at Exxon/Mobil say it makes the oil a little abrasive in too high a concentration. It works great at startup (cause it's sitting on the surfaces), but the higher the concentration gets the less likelihood that it helps. A lot of oil makers have gotten away from high moly suspect for these reasons. Liqui-moly doesn't put it in the "off the shelf" products mostly. And it's in their name. So, WHY? Shawn |

If you REALLY care... https://testoil.com/ But that may be too much for many. I'm not sure I agree with the premise that it's not helpful on a used care. Might be VERY helpful for which "used car" to avoid. Shawn |

With that being said, I can see the abrasive argument for Mos2. However protection from LSPI bearing damage and startup wear tips the scales in it's favor by a large margin IMHO. But all of this is just bench racing, let's talk real world results. Are there many users posting examples of 10 year old 180+ mile engines outputting 150+hp per liter pushing 5500lbs (think about that, it's like pulling a 1000+lb trailer in your M and then flogging it all the time) running just straight oil up on Bob's? Or is just all hypothetical? I will acknowledge that my experience is anecdotal and could just be a lucky fluke, but considering this is on the original n63 engine, the engine that BMW lost a class action lawsuit over....well then it's one hell of a fluke.

There are always outliers. And even among cars considered lemons, some examples do just fine. 1 high mileage motor using moly does not convince me that any example of the same motor using moly would wear the same.

Time will tell if the S63TU3 in the F90 suffer the same fate as previous generations. If they do, right around the 5-6 year mark is where we should start seeing reports of random engine failure in both tuned and non-tuned engines alike creep in. IMHO, the randomness is not random at all but rather the culmination of wear on the bearings caused by LSPI and pre-ignition events breaking the oil film and destroying the bearings surface overtime until it eventually complete oil film failure and engine seizure/spun bearings. Moly has been shown to decrease LSPI while at the same time having greatly increasing the shear strength of the carrier oil, adding a protective buffer against the crushing forces from a LSPI event. Again just my opinion so take it for what its worth, however if I am right, others will eventually chime in and hopefully this info will help owners enjoy their M's for many years to come. |

It won’t hurt. I bought some and started adding it. Supposedly ZDDP is also helpful in reducing the likelihood of LSPI. I am not convinced LSPI is the sole cause of engine failures, but it may be responsible for some failures. There are several theories as to what causes LSPI and moly does not address all theories. There are also theories as to what kinds of engines are more likely to be affected by LSPI and moderate to larger displacement V8s are not first among those mentioned. Maybe the best thing is to stop chasing fuel economy. Turn off auto start stop. Use sport settings for the engine and transmission.

But why doesn't Liqui-Moly make a BMW approved oil, and one that has JUST THE RIGHT AMOUNT of molybdenum in it with an explanation. I have no problems with Moly. It was one of the first really good dry phase lubricants that could be added to a liquid in suspension. But, to your anecdotal question, there are certainly some guys on Bobistheoilguy and many other forums running REALLY HIGH hp/L cars on nothing but Mobil-1. Also Redline. And Motul. Which are all VERY different products. Head to head, who the hell knows. As I've said before, what really distinguishes the "lasters" versus the "failures" are the conservative tunes, who change oil REGULARLY, and choose a premium off the shelf manufacturer oil. There are still failures. Just like there are always going to be. Shawn |

Holy mother.
I know we do ACTUALLY have to say this, cause I've seen guys in Lamborghini's putting Sheetz or Wawa gas in their cars. But yes, REALLY? Are you gonna debate whether or not you're going to use 5W-30 or 5W-40 oil in your car and skimp $0.15 per gallon on fuel? REALLY? Shawn |

Hmmm, Can you show me some receipts and provide some links to those examples? Looking for something comparable to mine as a N/A engine in a lightweight sedan is not the same. So examples of just oil (any oil) no additive, turbo charged engines with more then 180k miles on the clock pushing 150hp+ per liter in a heavy 2+ ton truck or SUV applications? If there are many of those examples up on Bob's, then it will be clear my experience is nothing exceptional and I'll go radio silent about Mos2. I agree with you that regular oil changes and conservative tunes are key to engine longevity along with decent gas. IMHO, e30 should be the gold standard in all BMW twin turbo v8's or a mix of race gas with 91/93 with a 94+ aki goal. Would my tune be considered conservative though? ESS tuning would not push the boost/timing any higher then stage 2 with the original n63 so I had to add a jb4 on top of it to reach my goal (make it as fast as new X5M competition) I am pushing 50% more power over stock n63 rated 408hp and double the boost, I am dancing on the ragged edge of the stock turbos efficiency envelope, especially considering this not the M variant so it has cast pistons, less oil sprayers, and smaller non twin scroll turbos.

Why doesn't LiquiMoly make an oil with the appropriate amount of moly that's not approved by BMW. Why sell a "supplement"? Why not just the one that has what they think the right amount is? Shawn |

If you are in doubt, please see the BMW recommend extended engine oil change intervals and the outright lie of never needing to change your transmission oil as further evidence as to where drive train life ranks on BMW (or any high end auto manufactures) list of priorities. So again what is in for BMW if an oil or additive shows outstanding wear and engine life performance past 100k miles? Now in the past this was more acceptable, however we are living in the last days of the V8. The latest rev of the S63 engine in the F90 will be one of the last ever made. IMHO the F90 will become a collectors item in the future because of this and extending the engines life is more important then ever. And even if you don't care about such things, the bonus is trade-in/resale values will go through the roof. All of this is a moot point though if just straight oil is all that is needed as you indicated to reach well over 100k miles in high performance forced induction engines pushing heavy vehicles. I need to see some real life examples to believe that however as parsing the previous gen M5 & X5M forums & speaking to previous gen owners, as well as the absolute dismal resale values past 100K miles appears to indicate engines go BOOM in the 100-130k mile range with engine bearing failure due to oil film breakdown being by far the dominant cause. Almost like its working as intended.... Last edited by Sophisticated Redneck; 10-17-2022 at 12:26 PM.. |
