Broad-Range Synthetic Diesel Engine Oil Pays for Itself with All-Weather Performance, Wear Protection and Fuel Economy
Monolec Ultra® Syn Heavy Duty Engine Oil is a multiviscosity SAE 5W-40 synthetic oil for diesel engines that delivers outstanding year-round performance, fuel efficiency and extended drains. 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 synthetic base oil and exclusive additive package, it provides reliable lubrication – even in low temperatures – without the shear stability and viscosity problems of conventional diesel engine oils. Its high viscosity index indicates less change in viscosity over a broad temperature range.
A primary advantage of 5W-40 vs. 15W-40 engine oil is better fuel economy. In a controlled lab setting, GM 6.5L dyno testing showed a 1.5-1.6% fuel economy improvement. In addition, lowviscosity oils achieve flow quickly during cold startups. Most engine wear occurs within the first two to five minutes of starting. However, conventional low-viscosity oils have not always provided adequate oil film at operating temperatures, which resulted in increased wear and made it difficult to obtain OEM approvals. Monolec Ultra Syn eliminates this problem with its ability to flow quickly in cold weather and maintain viscosity at operating temperatures. It also meets all major OEM approvals.
Monolec Ultra® Syn Heavy Duty Engine Oil lubricates parts faster, prevents wear during operation, and decreases fuel consumption – making it the smart choice for fleet managers and owner operators who want better fuel economy and reliable low temperature performance.

N/A
LE’s proprietary additives are used exclusively in LE lubricants. Monolec Ultra® Syn Heavy Duty 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. |
