Are these compounds detected in UOA?

[jorton]

"Organic fatty acids and amides, lard oil, high molecular weight organic phosphorus and phosphoric acid esters."

Which elements in an UOA report show these compounds?

 

[hooligan24]

thats looks familiar, is that GM's supercharger oil?

 

[gtx510]

lard in eaton s/c oil?

No. Not the compounds, but the yes elemental P would be detected and you would not know it's source.

It's a list of friction modifiers from "Lubrication Design".

Are there other FM that don't show on oil analysis reports?

Yes all the organics, amines, etc. will go undetected in elemental analysis.

Amines might boost the TBN a bit, some will slightly change the viscosity, etc. Low cost OA's are very limited.

This might be a noob question, but do organics increase the solubility of Group II/II+/III motor oils for cleaning purposes?

 

[Pablo]

Well of course they help cleaning ability because we are talking about esters, amines, amides, etc.

Not sure what you mean when you write "do organics increase the solubility of Group II/II+/III motor oils.."

 

[Nickdfresh]

Someone, and educated troll methinks, once implied that a large part of AutoRX's cleaning ability was its use of organics derived from animal fats that intensified the "cleaning" effect of even the cheapest modern oil because it was made more soluble to sludge and deposits. And that Group I oils were actually better for cleaning, if not lubricating and keeping things clean..

I was wondering if there was any truth to this...

So are these FM compounds some of the "proprietary additives" motor oil companies list on MSDS and product descriptions?

 

[Pablo]

Yes, indeed they can be.

sheeps wool lanolin esters IIRC.
G-I was better with the cleaning of ARX because of the larger percentage of unsaturated hydrocarbons and higher solvency is able to carry the ester sludge away from the surface once they had dissolved the sludge on the surface I think is the theory Frank presented.
