the oil evaporation is leaner and not an instant drop like upside down hockey stick graph, otherwise oil manufacturers would evaporate before use. And at the same time with the time you have oils degradation as additives level depleting, oxidation, thermal breakdown, contamination, sludge...

Any oil with LL04 approval (approved, not just recommended) off a Walmart shelf will have HTHS 3.5 and above. Viscosity is not important, hths is, and LL04 commonly is w30 I am using now Liqui Moly with LL04, but also thinking to switch Motul

I have the same car, same model year, and the same engine—with 85k miles on it. The FE spec oils are built for better fuel economy, mainly to meet tight U.S. efficiency standards. That’s why they have lower HTHS —which is fine for fuel savings, but not ideal if you care about long-term...

I agree. The golden rule right now (at least for me), eCore or holes, no metal on metal bypass valve as it never seals 100%, synthetic media, silicon ADV So the best bang for a buck plus higher quality now are Premium Guard made from multiple filter brands, Carquest Premium, Microgard Select, etc

Walmart associates would not care except asking why did you open product without purchasing it. Is it even legal to open something and put it back. Especially some filters have sealed boxes

With that quality control, I would not risk it. Who knows what else can be found after cutting it open. We have seen anti drain valves with holes, failed glue, ripped media, etc

I saw metal pieces stuck in louvers like this in multiple areas of the second oil filter. I returned both as I have no trust left in the product. Why run it and risk it, if could get a full refund and buy better quality filters, which I did first one zoomed

Do you have any NOACK info for it by any chance?

There is actually EFE version of it (5W-30) 8100 X-CLEAN EFE 5W-30, which might be better than 8100 X-CLEAN EFE 5W-30. Higher flash, lower pour point, higher TBN, NOACK 7.7...

Yes I am aware of it. I was just confirming your point which you did above. What I was stating any oil can share bellow grade and start thickening for many reasons like wrong applications, longer use than recommended, etc. this was no the case. The oil was usable even after the thickening. I...

Possible, although this engine burns 0% visible oil through 5K miles OCIs including multiple LM uses. 133k miles now I don’t think it is low quality base oil, just group 3

It is miles, it is right in the report I don’t believe it was sheared so become unusable and then thicken. It is only 5600 miles 50-70% highway and this oil has long life approvals. BMW Longlife-04 MB-Freigabe 229.51 VW 505 00 VW 505 01 VW 502 00 There multiple reports this oil served...

I saw similar results after full VW recommended 12 K km OCI in VWs where Viscosity of LM did not drop. You can enable auto translation and see viscosity check at 3:00 And I assume it is with bad quality high sulphur gas

Here after 5600 still LM showed 11.9

No it will not It is bmw long life approved I personally used LM long life high tech with LL04 approval in my g37 for over 5K miles and sent to BS. The viscosity still was above 11. That vq37 engine is running hot and known for searing engine oils like crazy. LM uses high quality Viscosity...

Why do you care about 40, if HTHS is >3.5 it is all good. Additionally Top Tec 4210 has viscosity about 11.9. it is a very thick W30 almost 40

a bunch, also all SDS available www.liqui-moly.com But for my BMW I was considering Special Tec B FE SAE 0W-30 and Top Tec 4210 SAE 0W-30. Both have 1-Decene PAO 30-60% Also what you mean by "truly synthetic"? There no group IV only 100% oils commonly available

Same way. Liqui Moly is often unfairly put down on this forum. The reality is that they own and operate their own oil manufacturing facility and R&D center in Germany, ensuring full control over quality and formulation. While it's true they may not use GTL, they do offer oils that contain Group...

Both CCS and Pour points are indirectly correlated, both measured differently but both dependent on the temperature both tests assess low-temperature properties, but yeah,the CCS test is considered a more relevant indicator of an oil's performance during cold engine start-up than the pour point.
