do any one have an oil anaysis report sample. I want to know what need my oil analysis report to have.
am condition monitoring engineer.

A typical engine oil analysis report is pasted below for your reference.Sorry I could not attach the same.

thak you,
the report we receive is below.
I think that the report do not show realy the oil condition,and the comment is function of the oil contamination.

Satisfactory for continued service.

Viscosity 40 C cSt 115
Closed Flash Point C 200+
Total Insolubles % 0.2
Total Base Number 10.9
Water Content % <0.20
Sodium ppm 1
Copper ppm 3
Lead ppm N.D.
Tin ppm N.D.
Aluminium ppm 4
Silver ppm N.D.
Iron ppm 6
Molybdenum ppm 1
Chromium ppm N.D.
Manganese ppm 1
Nickel ppm N.D.
Titanium ppm N.D. .
Vanadium ppm N.D.
Silicon ppm 11

Though the various parameters are well within specification limits,a low flash point,presence of sodium and a water content of 0.2% are indicative of problems assiciated with engine.

Generally the physico chemical parameters shows the condition of the engine oil and wear metal analysis shows the condition of the engine.

To get an more compete conclution you need to know a lot more parameters like oil type, hrs engine, hrs oil and more.

Overall it looks to have low wear element content. Be aware that analysis is most likely done by ICP or RDE meaning maximum particle size analysed is 6-8 µm. If you have had recent engine problems you should check oil filters for larger wear debries.

Hello , just wonder if this is after using a bypass oil filter ?
Also because i am not a full member here could you put me in touch with Mr Smiley who was gathering data on bypass oil filters
Kind regards
Johno

the concentration of Sodium is low, it could be a problem in the procedure of taking the sample? or the proper storage of the sample containers?
