Lubrication Engineers (LE) introduces a new engine oil for heavy-duty vehicles, its 5W-40 Monolec Ultra Syn Heavy Duty Engine Oil (8854). The company stated typical applications for this oil include Class 8 tractor trailer trucks as well as construction vehicles and other off-road equipment.
The company said this oil reliably lubricates diesel engines, even in low-temperature environments, without shear stability and viscosity problems. It has a high viscosity index, which prevents for changes in viscosity over a broad operating temperature range, LE stated. The company also said that in a controlled lab setting, GM 6.5L dyno testing showed a 1.5-1.6% fuel economy improvement for 5W-40 oils over SAE 15W-40 oils.
Authorized OEM approvals for Monolec Ultra Syn Heavy Duty Engine Oil include, but are not limited to, Caterpillar, Cummins, Detroit, Mack, Mercedes-Benz, Renault, and Volvo. Monolec 8854 also provides the necessary protection for modern low-emission engines, per CJ-4 standards, according to LE.
