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.


2007 Goldwing + Rotella T 15W-40 CJ-4. It works; I'm happy.

Boron is basically an anti-oxidant Has some anti-wear in different cases. You won't see a decent group I oil without it, but it can often be left out of group II, group III, or traditional synthetics.

Here is one of the most complete wear metals charts I've seen in a while

I like the report, Im gonna get a degree in chemistry someday. Im glad someone out there knows how to make all those elements stay together for 500k miles. Me, I just want it to run right, bottom line. amen

One more thing. A lot more engines are being assembled these days with Moly rings. Ring wear will show up as or with the moly that might be used as an antiwear/antioxidant.

Condemnation limits vary per engine and engine construction. Those that are published (CAT, Cummins, Detroit, etc.) are extremely high and not close to what is obtainable.

This is not bad but what about what the numbers mean? I mean is a high number or low number better for each category?

+1 After looking at some VOA results on different oils, PCMO and Diesel, BORON is becoming more of an additive in Synthetic and Dino oils.


I get by with a little help from my friends....listen with your eyes....it's the ONLY way to believe what you hear...

How about the different tolerances of each equipment. All factories have their own, so, to be sure of each UOA you should also know the different allowances or minimuns.

Blackstones will give averages for most engine types for you to compare results to. For a 1.9 TD I would not be too concerned until the Iron was over 50 ppm, Aluminium over 10, Chrome or Lead over 5 and Silicon from the air filter over 20.

The 5W/40 figures for a UOA are as follows:
SUS Vis at 210F: 66 - 78
cSt Vis at 100C: 11.9 - 15.3
Flash in F: > 410
Fuel % < 2
Antifreeze: 0
Water% < 0.1
Insolubles: < 0.8
TBN: > 1 (Normal) >3 (Severe service)

The trend is as important as the actual figures for wear metals, as every engine is subject to different use and to complicate matters you might have a temporary particle streak occur and rebuilt or new engines produce different figures.

The car should be driven at normal speeds for half an hour plus before draining the oil and the sample taken mid stream into a clean container.
