I am just saying this for those actually willing to understand this. And I know very well that discussion on BITOG. But this is the question that no one who gives these ridiculous explanations ever answer: why Redline cannot be approved? Simple is that oxidation is too high. If acidity is high and impacts performance, it is irrelevant where it comes from. |

Of course I did. But I am not sure you actually fallowing development of RL oils.
RL had huge overhaul of its lineup somewhere 2011 and again in 2015. ZDDP in all their regular Performance lineup is up to limits required by Porsche A40, MB229.3 and 229.5, BMW LL01, VW502.00. There is no RL Performance oil since than with additives that are above those limits and are in line with other oils, sometimes lower (Mobil1 0W40). The oxidation is the issue. There is no other way around it. The chromatography/mass spectrometry of RL oils shows much higher acidity than regular oils. Other oils have that issue where a lot of easters are present. Mobil1 ESP 5W30 is not approved for current BMW LL04 as it contains around 10% esters and BMW in 2018 made oxidation requirements more ridiculous than they were. I personally would use Redline any time. I have it in my gearbox, i have it in my differentials, I even have it in my Sienna minivan. But they ain't going to see change interval like regular fluids. |

I went with Ravenol, previously use LM and Motul X8100. Reason is polyalphaolefin (PAO) based, polymer additives, low viscosity when cold, low viscosity when hot which helps with tight bearing clearance. Stable and doesn't change viscosity towards the end of the life. My track buddies use Ravenol, only oil they found to keep the temps down on the track.

Update: Picked up an ordered G80 MT and this is a repost from another thread but appropriate here as well.
I talked with Dave Granquist at Redline Oil and we had an in depth conversation. He said the low budget oil analyses misread the oxygenated ester molecules, read as oxidation. He stated that they are polarized (esters) and the oxygen atoms make the ester attraction to the engine. Their oils don't suffer from premature oxidation and the readings are misleading. Also, regarding the correct oil for the new M3 / S58 engine __ it is the low ash Euro series high performance oil. Group 4/5 with the proper additive package. 5w30. Soon the 0W30 will be added to Euro series. so glad I called him today. all set, having talked with the authority…. https://www.redlineoil.com/euro-series-5w30-motor-oil

I noticed Liqui-Moly's Race Tech GT1 formulation has been updated and none of their current specs match what's on the first page. Maybe others have been updated to new formulas as well?

Most important specs for our motors are thinnest viscosity of its class (bearing clearance) and HTHS (bearing protection). Everything else, not as important. I hear a lot of "I've been using x for 2yrs, it's fine." Stick with OEM or find an oil that has the lowest viscosity and highest HTHS as OEM. Otherwise, don't move away if there's not improvements.

Liqui-Moly Race Tech does not have an HTHS of 3.5, their spec sheet only says "above 3.5" and that's the way their brand has chosen to handle marketing. I used to manage a shop and sold many brands of oil including LM, brought it up to their US sales department that they may want to list more relevant HTHS numbers because oil samples I sent in for analysis indicated that it had a competitively high HTHS in reality (it was something like 5.6 or 5.7 if I remember). LM headquarters decided not to update how they advertise their oil so they stick with "above 3.5". Liqui-Moly is not the best option in my opinion but wanted to clarify this since it's a common misconception about their product. |

Second, VOA that determines HTHS is very expensive. Polaris, Blackstone etc. won't do that. On other hand, yes, Liqui Moly is mediocre oil. They have always been. They were first to jump onto Hydrocracked train in 90's in Europe, advertising it as next best thing after sliced bread. |

Has anyone tried the new Amsoil 10w-60 in their S65? The HTHS of 6.6 is so much higher that I was concerned, I don't know enough to know if this could be a bad thing so I asked their technical email. They told me there is no harm in having such a high HTHS result and they claim it would only improve wear protection and shear stability.
