8800-8801, 8130-8131 MONOLEC® ENGINE OIL

Extended-Drain CK-4 Disel Engine Oil Offers Ultimate Package of Performance & Protection for Diesel Engines

Monolec Ultra® Engine Oil (8800-8801 & 8130-8131) 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.

LE's proprietary additives are used exclusively in LE lubricants. Monolec® 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.
