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

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.
