15W40 Full Synthetic Diesel Engine Oil, 5 Gallon Pail - Roughly 4.5 Gallons Left, Very Slow Leak
Heavy-duty diesel engines (HDDE) fitted with exhaust after-treatment systems, e.g. exhaust gas recirculation (EGR), diesel particulate filters (DPF) or selective catalytic reduction (SCR), which require a low-ash lubricant to meet current emissions requirement.
Heavy-duty diesel engines operating continuously under very high speed, high temp or heavy load conditions, including on and off-highway, trucking, bus, mining, construction, agriculture and marine applications in the world’s harshest environment.
Fully backward compatible to those older HDDE using conventional designs without exhaust after-treatment systems.
