I have used some Liqui Moly in the past and liked it, product 4600 5W-30 to be exact. Does this extremely poor sheer test result mean all of Liqui Moly oils are garbage? I have been looking at their 4210 0W-30 oil, (have never purchased it or used it yet) which has some group 4 and the BMW LL-04 rating, which I don't think the Molygen Lake Speed tested does not have. Would anything in the 4210 specs tell you it may do better in the sheer testing? I noticed that the Molygen rated number 1 or two in the other tests, which seems to be practically ignored. I almost appear to be a Liqui Moly fanboy I guess, I try not to be a fanboy of any brand. I do try to do USA owned products, which means I would have to stick to Mobil or Conoco Phillips (Red Line, Kendall etc.) for shelf oils, or Amsoil, HPL and Driven boutiques, which I don't use right now. Anyhow, Liqui Moly is expensive for a mostly group 3 base oil product. I do know, at least in my past experience, they do make some decent stuff, worth the price? maybe not. As long as I am putting stuff out there, I am currently using Motul 8100 X Clean + EFE 5W-30, which I also like. Next, I plan to use either this same oil in their 0W-30 version or somebody else's 0W-30. I already used the Mobil 1 ESP 0W-30, that is off the list for now.
