can a UOA (UATFA) tell me if it meets MerV specs?

Wondering if i can just drop 4 oz of the iffy lube garbage (fresh, but what is it?) and send off for a UOA and they can tell me if it's good to go for my Mercon V application.
 
As unDummy says, nope. A UOA will not tell you what kind of oil it is, only what's in it to some degree. You'll need something more involved such as an FT-IR run to see if it's MercV. Even at that, you'll need someone failure with not only reading the results of the FT-IR but someone who also knows what a MercV oil should look like.

If you are that worried about it I'd just drain and refill with a known quality product. A lot less expensive than an FT-IR (or GC, etc) test.
 
Isn't it easier to ask them what fluid they put in it and check the label or the data sheet for the proper Mercon spec? Once the analysis company has that info, they should be able to tell you whether it needs replacing or not. That is basically what you pay them for.
 
I've been round and round with the regional rep, which corporate JL put me in touch with...
just wondering...

I'll just do a drain and fill
