Monolec Ultra® Syn Heavy Duty Engine Oil is a broad-range multiviscosity synthetic oil for diesel engines that delivers outstanding year-round performance, wear protection, fuel efficiency and extended drains. With its synthetic base oil and exclusive additive package, this SAE 5W-40 formulation reliably lubricates diesel engines, even in low-temperature conditions, without the shear stability and viscosity problems of conventional diesel engine oils. Its high viscosity index indicates less change in viscosity over a broad operating temperature range. (Monolec Ultra 8854 & 8855 are the same, except 8855 is undyed.)
