Are you sure? That doesn't look like an anti-LSPI formula.It's recent.
Low Ca. It is LSPI friendly and it's from recent new plant. Moly/POE also offset LSPI events.Are you sure? That doesn't look like an anti-LSPI formula.
Could you name the source?
I can't speak to the VOA in your link. It's hard to read.Thank you. However, I cannot completely follow your answer. How does your statement match the following UOA of the Euro Series 5W-40 with API SP formulation? (Lower Ca + significant Mg)

That's why I asked above for the source of the VOA.
This looks like an older version (pre-2023).Oh, I'm sorry for that!
These are the additives of the tested Redline (API SP)

Again, the OP is a VOA of current SP 5w40 RL taking from their new plant in TN. I have no idea about the one you posted. I can barely read it and it's a used oil analysis not a VOA. And it's not even from the US.Excuse me, but the values are taken from an used oil analysis as I mentioned in #5. So the lower viscosity is due to the running time and fuel dilution.
The posted VOA of the 5w30 is very helpful. But it does confirm my view and shows that the VOA you've posted for the 5W-40 refers to the API SN. It is not similar at all to the one you posted, is it? Yours has no magnesium; 5w30 has 500 ppm. Your VOA shows a lot of boron, the one from 5w30 shows significantly less.
Sorry, but I can't really follow your arguments.
And ZDDP?Low Ca. It is LSPI friendly and it's from recent new plant. Moly/POE also offset LSPI events.
I really love the belly laugh I get every time you enthusiastically claim an oil’s performance can be comparatively graded against others based on their VOAs. “This is the most amazing oil ever!”Red line seems to be trying to beat just about every other boutique oil. All of their oil analysis I've seen seems great.
It looks like this product based on the viscosity above. HT/HS 4.4 & Noack 6%!!

Is the TBN of the Walmart oil also measured according to D4739? Or maybe rather to D2896?Especially when the oil in this thread has a TBN on par with the $20/5qt shelf at Walmart.
Depends on which lab did the test. Many labs today only use the used oil testing method since it requires fewer (and safer) chemicals to perform the test, and also gives comparable results between virgin & used TBN tests obtained from the same lab, which does not happen when the virgin oil testing standard is used for VOA and used oil standard for the UOA.Is the TBN of the Walmart oil also measured according to D4739? Or maybe rather to D2896?
The 5w40 VOA is from the new plant in TN from a recent purchase.I do not believe that the VOA shown above is up to date. Even Red Line has confirmed the significant amount of Mg in API SN+ and API SP. The VOA does not show this. Quite on the contrary to the linked 5w30.
A couple of things with regards to LSPI. It's not just the ratio of Ca to Mg but the amount of Zinc/Phosphorus also plays a role. If Z/P are high enough then you don't need Mg. This is why Full Saps Euro oils can "meet the performance requirements of SP". It's only when you start dropping Z/P (ex, ACEA Cx) that LSPI can occur in some engines. 40 grades which meet API SP don't have the same limits for Z/P unlike 30 grades and lower.Are you sure? That doesn't look like an anti-LSPI formula.
