Engine oil research

Below you will find a range of analyses of lubricating oil used in engines operating in CHP systems operating biogas as a basic fuel. Analyzing engine oil in the following scope, we are able to identify and issue a recommendation for its further operation in the system.

The level of contamination with metals and additives as well as the assessment of the abrasive quantity (condition of the device) allow assessing the efficiency of the filtration system.

  • Viscosity at 40°C, cSt
  • Viscosity at 100°C, cSt
  • Viscosity index
  • Water, %
  • Oxidation, Abs/cm
  • Nitration, Abs/cm
  • Coolant content
  • TAN mg KOH/g (acid number)
  • TBN mg KOH/g (basic number)
  • Self-service consumable metal content, ppm
  • Level of additives, ppm
  • Contamination level, ppm
