Monolec Ultra® Engine Oil

SKU: LE8800/LE8130

Typical Applications

  • On- and off-road diesel engines, including over-the-road tractor trailers, pickup trucks, construction and mining equipment, farming equipment, and more
  • Stationary diesel engines, such as generators and irrigation pumps
  • Backward compatible for use in older diesel engines

Monolec Ultra® Engine Oil provides exceptional performance and extended-drain service for on- and off-road diesel engines, including stationary engines. It has been formulated to exceed API’s CK-4 technology standards focusing on engine wear protection, oxidation stability, shear stability, resistance to aeration, and compatibility with low emission engines. With its superior formulation of select base oils and Monolec®, LE’s exclusive wear-reducing additive, Monolec Ultra offers dependable all-weather performance, reduces unscheduled downtime, and helps fleets achieve costs savings.

Proprietary Additives

LE’s proprietary additives are used exclusively in LE lubricants. Monolec Ultra® Engine 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.
