Yes, and in that second UOA, @burbguy82 saw cleaning on his dipstick and more crud on his magnetic drain plug. Probably can't say many if any synthetic blends are doing any cleaning. Best you could previously hope for is treading water and not laying down more deposits.

I think you’re confusing the link I posted for another member that’s not burbguy. If you click on the link you can see the OAI report that lists TBN.
If you follow that link, you'll see I posted two used oil analysis. The first one is the one you posted. 0W-20 in a Sierra. Second one was the 5W-30 in a Tahoe. No TBN (that I saw—maybe I missed it).

I also don't see oxidation at anywhere near the 33.2 claimed in the post you are quoting, in fact I see some pretty typical oxidation for used oil there, so no indication that there is any ester co-base in the 0W-20 synblend product he was running.
Edit: The 5W-30 used oil analysis shows oxidation at 11.7 for used oil, again, not indicative of any ester co-base in that product either.
I agree. Cleaning and not adding to deposits are a different thing. Another possibility is, just using a different oil. Of course, oils are different, formulated differently, one product could clean what the other leaves, just as a byproduct of a different chemistry. One not being "better" than the other, just skinning the cat in a different way.
I am not quite sold on the "synthetic" is better thing. Certain applications, synthetic lube is not suitable, such as perhaps in a hydraulic application. Some equipment specifically call for a conventional oil.
In my test that you mention, was in my daughters Tahoe, 5.3, bought used, well kept, and has been well kept for last 5 years or so, using Napa 5w30 mostly, 3000 of 6 month changes. The crud on the drain plug was not normal, so I can only extrapolate that the Amsoil SynBlend was the doer.
I have thought about using the synblend, but wish they made something in a 40 weight. I use my other stuff hard when I drive them and like the extra protection and a higher HTHS, fine for Tahoe, not ok for Big Block, IMO...might be wrong.
I would not hesitate to use anything from Amsoil, ever. Maybe not the gun oil, but everything else.
Gun cleaner and lube is actually real good. Gone through several bottles of each. I haven’t tried the spray version but the bottle cleaner is great.
It definitely smells like mineral spirits. I would not sway someone from using it, I am sure it is good......
Thanks I was going to mention that too but forgot. I wonder if they changed formulations. In this video, they review a VOA showing high oxidation.
Edit to add: in the follow up video, LSJ looks at the used oil analysis, and the oxidation dropped very significantly. He writes it off as the mixing with the previous oil, but I'm wondering if that initial oxidation is an error?!? I'm not sure I agree with his conclusion there. 33 to 13??

Yeah, I'm thinking the first reading was lab error.
If it’s in fact a lab error that’s hugely disappointing on Speedlogistix part.

It’s no secret Speed Diag has values all over the place. I like their layout better. For the meantime OAI remains King.

Lab errors happen and this isn't a huge issue and is generally easy to spot when the tool is used as intended to trend the results and look for significant anomalies.
The problem here seems to be some excitement and claims made about ester content based on this single VOA.
Are you talking about the spray? The bottles are almost identical to slip 2000. Zero smell and easily cleaned off hands.
The cleaner is offered in spray and bottles.
A wise way to think about it!

That's a bizarre conclusion, as oxidation generally goes one way -> up. Here's one of my used oil analysis:
Virgin oxidation was 24, after 10,800km (6,700 miles) it had increased to 42. Previous oil, Mobil 1 Extended Performance 0W-20 (sample #1) had a used oxidation value of 17 after about 6,000 miles (consistent with what we are seeing in the used AMSOIL oil I'd say).
don't remember if it was spray or not, i just remember it smelling like mineral spirits. it was non aerosol.....maybe they changed something in recent years? It did work well.

Did anyone ever do your test?
Multiple people
why ??
Not sure if you read the whole thread, but many speculate that this is a lower price point option for shops who want to be able to go full AMSOIL in their offerings, for local, independent shops.
Personally, I trust that AMSOIL would never blend a bad oil, so if your engine is easy on oil and your application allows it, I think it would work well for some people.
