Technical Articles and Case Study Related to this application

Gas engines have much high level gas fuel combustion process than diesel engines. Operation of Gas Engines are crtical, oil degradation can be easily caused and resulted by nitration or oxide of nitrogen. LubeCheck™ -natural gas engine oil analysis are highly efficient monitoring program to help in achieving maximum efficiency.


Industries: Oil and Gas exploration and production , Power Generation etc.

Test Description

Oil Sample Quantity: 100 ml.

Oil Sampling Location/Point

  • Follow OEMs recommended sampling location / point
  • In the absence of OEMs guidelines , recommended below for general guidance for sampling point /location

Possible location/point will be

  • At dipstick of engine - using fluid vacuum pump and plastic tube
  • Dedicated sampling valve installed upstream of the filter on the return line or
  • Dedicated sampling valve tap fitted to oil feed pipes or oil passages (upstream of the filter)

Sampling Tools & Devices

Sampling Techniques

Sampling Frequency

  • Initially , follow OEMs recommended sample interval for your equipment
  • In the absence of OEMs guidelines , recommended below for general guidance in establishing sample interval

Recommended Sampling Frequency (Sampling Interval)

Industry - Application Normal Use Intermittent Use
Natural Gas Engine

500 hours
or one month
and just prior to oil drain

Quarterly
and just prior to oil drain

Landfill Gas Engine
Bio Gas Engine
Sewer Gas Engine
250 to 500 hours*
or half-month to month
and just prior to oil drain
Quarterly
and just prior to oil drain


* Shorter sampling interval when sour gas (landfill gas or sewer gas ) is used as engine fuel .

Reports

LubeCheck™ Oil Analysis Report provide :-
  • Display an easy-to-read and understand.
  • Information for wear condition ,lubricant condition and contamination.
  • Interpretation and recommendation of the result . Option for Bilingual.
  • Color coded display of overall condition for present sample and history condition of previous sample.



  • Color coded problem highlights.
  • Provide new oil or reference oil for comparing result and as baseline.
  • Publish Alarm Limit range of the equipment and oil.
