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.

Full Synthetic Oil with Premium Additive Package Provides Unparalleled Benefits for Gasoline Engines

To provide the best protection for your car’s engine without sacrificing performance, endurance and efficiency, look no further than LE’s Monolec® Syn Engine Oil. LE has harnessed the latest technology and knowledge to formulate this high-quality, high-performance, proprietary synthetic engine oil for gasoline engines.

Available in SAE 0W-20, SAE 5W-20 and 5W-30 grades, LE’s Monolec Syn Engine Oil exceeds the minimum standards set by American Petroleum Institute (API), providing the ultimate combination of performance, protection, endurance and efficiency. It is a best in class 100 percent synthetic gasoline engine oil, and the secret to its superiority is the proprietary additive package designed to deliver resource-conserving fuel economy, protect emissions systems, keep engines clean, keep deposits to a minimum, and mitigates wear in Low-Speed Pre-Ignition (LSPI) conditions.

Whether you are a car enthusiast or the manager of a fleet of gasoline engines, you’ll appreciate Monolec Syn Engine Oil’s ability to keep your engines running for longer periods while safely extending the time between oil changes.

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.
