Fluids Solutions from NES-WES

Northeast-Western Energy Systems (“NES-WES”) has strategically partnered with Q8Oils to be an exclusive distributor to offer complete comprehensive fluids packages which include lube oil, gear box oil and coolant. Our goal is to provide the longest lasting oil life at the most cost-effective price that will significantly lower your overall lubricating oil costs. Q8Oils Mahler is a range of high-quality lubricants for engines using all types of gas, including natural gas, biogas, landfill gas, sewage and other highly polluted gases. These oils offer outstanding benefits such as high oxidation and nitration resistance for long service life, low ash deposit tendency and good resistance against pre-ignition, excellent anti wear properties to protect the engine against valve seat recession and high acid neutralizing capacities as a result of high Total Base Number (“TBN”) retention.

Gas engines are subjected to extreme operating conditions, especially around the combustion chamber. This results in significant technical challenges for lubricant manufacturers, particularly in terms of oxidation- and deposit control with outstanding TBN retention. Operating conditions vary substantially and Q8Oils can provide advice on the best oil for your application. NES-WES will perform comprehensive expert analysis and management of lube oil, coolant and fuel gas sampling to ensure adherence to OEM requirements.

The NES-WES Asset Performance Management Center allows you to monitor your oil life cycle through the MyPlant application. - https://myplant.neesys.com/myplant

  • Less oil filters, o-rings.
  • Less man hours.

Cleaner engines.

  • Traditional and modern type 'low TBN' products can give hard abrasive deposits (leading to ring sticking, etc..).

Longer oil drain.


poor quality oil

  • Hard abrassive deposits.
  • Thermal / oxidative stress on oil very high.
  • Issues: Ring sticking.
  • Liner Laquering.

HIGH quality oil

  • Clean pistons.
  • Clean liners (low oil consumption).
  • Good dispersancy / solubility (long filter life).

(Initial pH, measured at start of TAN test) IpH is a measure of the overall acidity of an used oil mixture. Pure water is said to be neutral (pH ~7.0). Solutions with a pH less than 7 are called acidic and solutions with a pH greater than 7 are called basic or alkaline.


Oxidation occurs as lubricant molecules are exposed to oxygen over long time periods. This process is accelerated by high operating temperatures.

Oxidation is perhaps the most predominant problem for natural gas engines.

Oxidation is often accompanied by:

  • viscosity increase
  • oil filter plugging
  • varnish, sludge and sediment formation
  • additive depletion
  • base oil breakdown
  • loss of lubricity
  • acid number (TAN) increase
  • loss in foam control
  • rust formation and corrosion

To avoid these problems it is binding to change the oil asap when the maximum value is reached.

Limit value is: maximum 20 Abs/cm*


Viscosity is measured @ 100º C (@ 40º C) and reported in mm²/s or cSt. The result should be compared with the fresh oil viscosity and can deviate for several reasons:

Increase due to:

  • Oil aging (also increase in oxidation and nitration values)
  • Contamination (water, glycol)
  • Insolubles (rare for gas engines, only soot of fuel jet ignition)
  • Evaporation of easily boiling components


  • Dilution (only diesel – dual fuel engines - ignition process)
  • Shearing of components (thickener, used to reach SAE 40 grade)
  • Top up with thinner oil

Viscosity increase is limited to max 3 cSt

Total Acid Number

  • Total Acid number (TAN or AN –Acid Number) is an indication of increased acid levels in gas engine oils, frequently accompanied by viscosity increases.
  • TAN tests are often used to establish optimum oil drain intervals for many types of gas engines.
  • High TAN is an indicator of nitration, oxidation (in general aging) and contamination.

TAN limit max: Fresh oil value + 2.5 mg KOH/g)*

Total Base Number

  • The Total Base number (TBN) is an indication of the reserve alkalinity of an engine oil, thus the ability to counteract acids.
  • The TBN is expressed as mg KOH/g (mg kaliumhydroxide per g of oil)
  • The used oil TBN must be compared with the fresh oil TBN value.
  • Low TBN values are usually accompanied by increase in viscosity and TAN. (Rule of thumb: TBN number must always be higher than TAN number)
