Advanced formula provides superior oxidation stability & deposit control for gas combustion turbines

Formulated specifically for use in gas combustion turbines, Endure™ Turbine Oil (6481-6482) features a unique blend of highly refined base oils and proprietary additive technology. Its advanced formula provides superior oxidative and thermal stability while preventing varnish and sludge formation on critical surfaces. Endure Turbine Oil ensures long-lasting, trouble-free performance in gas combustion turbines, minimizing unplanned outages and maximizing uptime.

Oil problems are estimated to be the cause of nearly one-fifth of all forced turbine outages, according to “A Comprehensive Guide to Industrial Turbine Lubricants,” by Afton Chemical Corp. Chief among the various mechanisms inside a turbine system that can result in degradation of the oil while in service are oxidation and thermal degradation.

  • Oxidation is the reaction of oxygen with a substance. When lubricants are exposed to oxygen, reactions occur that create new substances. For every 10°C (18°F) elevation in temperature, the rate of lubricant oxidation doubles, meaning at higher temperatures reactions speed up.
  • Thermal degradation occurs during micro-dieseling, cavitation and static discharge events, which produce very high, localized temperatures that thermally degrade the oil molecules in a lubricant.

Oxidation and thermal degradation can lead to base fluid breakdown, additive depletion, increased viscosity, varnish and sludge formation, increased acid number, increased foaming, loss of water separation properties, filter plugging, valve sticking, and rust and corrosion. Bottom line – the lubricant’s life span is shortened and equipment reliability is compromised. LE developed Endure Turbine Oil to address these problems.

Beneficial Qualities

N/A
  • Exhibits superior oxidative and thermal stability for long-term performance
  • Inhibits varnish, sludge and deposit formation
  • Exhibits superior air release properties and suppresses foam
  • Provides outstanding rust, corrosion and anti-wear protection
  • Separates readily from water
  • Is filterable for long-term oil cleanliness

Proprietary Additive

N/A

LE’s proprietary additivesare used exclusively in LElubricants. Monolec Turbine Oil contains Monolec.


Monolec® wear-reducing additive creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances. An invaluable component in LE’s engine oils, industrial oils and many of its other lubricants, Monolec allows opposing surfaces to slide by one another, greatly reducing friction, heat and wear.
