I think Mr. Drive By Accuser has left the thread...
___________________Are you referring to Amsoil Manual Transmission & Transaxle Gear Lube 75W-90 or Manual Synchromesh Transmission Fluid 5W-30?

Yeah....no. Base oil composition drives the virgin oxidation values. Fluids containing esters will not have a virgin oxidation number of 0.
Correct. AMSOIL MTF has a baseline of 37 absorption units right out of the bottle. It really didn't change when you consider the residual fluid in the transmission.
So we have a misinterpreted single UOA, a picture of a magnet with ferrous debris and a claim.
OP - what is Amsoil telling you?
I would absolutely love to see a UOA of the used initial Honda factory fluid at any mileage. That would be telling. Not so much after the Amsoil fluid, unless you switched again to the Amsoil MTF.

Still can't believe Amsoil would recommend a product "not for use in LSD" when the car has exactly that.
If I didn't post this years ago, here's an updated UOA for Honda's MTF that Amsoil dealer Pablo requested. After buying the car I changed to Amsoil's Synchromesh almost right away. After the first UOA -- and hearing of two similar problems from my buds over at 9thCivic.com, I switched back to the OEM. UOA quickly started to improve, as shown here.
Note: Wanting to be absolutely certain of my conclusions, I also sent a sample (taken at the same time) to OilAnalyzers, the Amsoil lab. Results were almost identical.
In other words, results improved dramatically once a proper lube was used, i.e., one intended for limited slip diffs. Keep in mind I was an Amsoil cult follower like some of you. They could do no wrong. "Lifetime" member, the week-long training academy ($1,000 at the time) a garage with thousands in inventory, etc.
While I have no extensive knowledge of Amsoil's recent test results versus other lubes -- who can be impressed when they compare Amsoil performance to minimum GM standards? That is not the Amsoil I knew. They'd go toe-to-toe with all the other lubes and bury them in every test. Don't they still do oil v. oil comparisons using the 4-ball D4172 and other ASTM procedures? (except for Noack)
Here's something completely anecdotal: Take it FWIW, probably not much since you weren't there.
Like dozens of others I spent a week in Superior with corporate insiders. Ate lunch with them, attended classes with "Bud Weiser" (his real name), and of course enjoyed happy hour. Bottom line? I wasn't impressed. Even back then (mid 90's) it was apparent that the hard nosed, no compromise founder known as "AJ" was turning the company over to his young son, Alan and his buddy Dean. Have no idea who's running it now, probably Alan. Nice enough guy for sure. Just not convinced he has the same core values about quality as the ole' man. Certainly not the impression I got. Another thing that struck me was how small the operation was. Yes, they had a big warehouse and plenty of raw materials stored in their field tanks. (The first view of Lake Superior coming over the hill is one of the most spectacular you'll ever see) But the company itself and number of ppl running it were a lot smaller than I had envisioned. Perhaps that's good; could mean "lean and mean". That part is irrelevant. I'm more concerned with the underlying philosophy... which historically is "first in synthetics", not only the first company to do synthetics but the very best possible oil you can buy, period. And they could prove it in each and every case.
Back to the Synchromesh MTF. It's not that the company made a mistake and wouldn't admit it that bugs me. No, it were the insights into how the so-called Amsoil "warranty" works, which I saw in detail. If dealers and users harbor any illusion about Amsoil's willingness to back up their products, know this: You will literally need to litigate. You will need to prove beyond all doubt that it was an Amsoil product -- and nothing but -- that has caused your issue. Which is basically impossible. And as I found, you'll also need to keep using the fluid long enough to destroy your equipment, after which they will probably say the equipment was defective anyway. Yeah, good luck with that.
