Superior Single Grade Oil Extends Drains in Diesel Engines 

Monolec® GFS Engine Oils are a family of SAE 30 through 50 straight-grade engine oils formulated for extended drain service, primarily in off-road diesel engines. They contain Monolec, LE’s exclusive wear-reducing additive, and are specified mostly for engines but are also sometimes used in industrial applications, such as air compressors.

Proprietary Additives

 N/A

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