0w-16 Pour Point: Mobil 1 Vs. Amsoil Vs. HPL

[Sienna dude]

Why does Mobil 1 have a better point? Can a good pour point be the sign of PAO? I don't know any 0w16 with better pour point than Mobil 1's. The worst I have seen is Valvoline's -39.

Rounding error?

Pour point is only part of the usefulness of the engine oil,,CCS and MRV plays a large point of the oils ability at cold startup at their given viscosity at a set temperature, read some past threads to learn about this.

Correction: My bad, that was the regular HPL, this is their flagship premium plus 0w16. This beats Mobil 1's pour point.

Yeah, but pour point by itself can indicate PAO presence. Lets wait for some more replies. HPL's pour point gets better as their price goes up. HPL's -61 degrees C is the best by far.
Oh, a past thread about majority PAO in Mobil 1 0w16 made me start this thread.

Also check they are using the same test standard, to make sure you are comparing apples with apples. I was looking at Castrol Edge 5W30 A3/B4 and they used D97 for PP, and D93 for FP. They oil gave -39C and +210C respectively. I think its a Group-III.

Your first image shows they use the same D97 for PP but a different D92 for FP. So we can compare the PP but not the FP.

Oh yeah, let me double check. In the meantime, do you know what that is between 50 and 75%?

 

[SR5]

Greater than 50% but less than 75%

 

[Sienna dude]

Greater than 50% but less than 75%

Yes, but what is that ingredient?

Also, all three are D97 and D92, exact tests, nothing different.

Distilled Heavy: These are hydrocarbons obtained through the process of distillation from crude oil or synthetic processes. "Heavy" indicates a higher boiling point, meaning the hydrocarbons are larger and have more carbon atoms.

C18-80: This signifies the range of carbon atoms in the hydrocarbon molecules. In this case, the molecules have between 18 and 80 carbon atoms. While some results specify C18-C50, the C18-80 range suggests it encompasses heavier, longer-chain hydrocarbons.
Branched, Cyclic and Linear: This describes the different molecular structures of the hydrocarbons.

Please translate it to English, PAO or no PAO?

PAOs are produced through synthesizing oligomers of either 1-decene or 1-dodecene. Neither of which are present in that ingredient.

PAO = 1-decene or 1-dodecene.

 

[SR5]

Yes, but what is that ingredient?

Sorry, I was too literal, I was looking at the "-". Laugh!
Not sure of the chemistry, I could guess Group-III or GTL.

I think PAO (Group-IV) is hydrogenated homopolymers of 1-Decene, CAS # 872-05-9

Also, all three are D97

Good, compare away.

So great pour point doesn't mean great base oil

 

[facility1]

Safety data sheets can tell you some what is in the oil, as they are there for material safety reasons only,, and not a manufactures/blenders formulation recipe which is regarded as confidential information, what actually is in the oil is to be determined by much more extensive tests and not the run of the mill Blackstone etc testing. and by the way there are really great formulations using group 3 blends and also GTL base oils that are quite completive to the more $$$ base oils, really depends on your use of performance requirements, availability, and pocket book.

Great pour point is just one indicator of an excellent fully formulated oil, PAO or not. But PAO laden oils do typically have the lower pour point

I hate reading the tea leaves, especially safety data sheets, but I would read it as:
50 to 75 % Group-III or GTL,
about 7% additives and stuff,
with the remainder possibly being PAO, because if memory serves me, you don't have to declare PAO in a SDS.

Are there some kind of additives that improve pour point?

Yes, pour point depressant
