Very nice. This might be a good sticky at the top of the UOA section for all to reference.

Generally ok.....the viscosity table could be quite misleading. Atleast drop the "w"s Better to just post the whole table from J300: http://www.infineum.com/information/api-viscosity-2004.html

So, to help out an oil-dork, what should the numbers be for a multi-vis, say, RTS 5-40?

For Admin, would it be possible to update the above info with oxidation, nitration and sulfation? This one specifically for myself, just a reference of the numbers on what is high and low. But also for others.
I know one way they are measured is using a spectrometer with how much infrared light is absorbed by the products of oxidation, nitration, sulfation, but not what is acceptable, high and low. Some uoa's also are coming through with just the number...Blackstone usually has perameters/guidelines, but some don't.

I also wanted to request "condemnation" limits, or at least numbers at which we should start wondering.

TBN explanation would be nice too!!

You missed Antimony - used by some oils in their add-pack; I think it's an anti-oxidant?

Not that many labs test for Antimony. I have seen Amsoil's OAI testing and Polaris show it in there UOA reports. I thinks Schaeffer's uses Antimony as a high pressure additive.

I think Boron is becoming part of the additive pack of some oils ... Rotella CJ-4 comes to mind as having increased the Boron.
