Features and Benefits

Today's low emission engines place increasing demands on engine lubricants. Tighter engine designs reduce oil consumption, resulting in less fresh oil make-up to replenish depleted additives. Higher piston top ring positioning brings the oil film closer to the extreme combustion temperatures increasing thermal stress on the lubricant. Higher fuel injection pressure and retarded timing improve burn efficiency, but also increase engine part loading, temperatures, and soot in the oil. The advanced technology in Mobil Delvac 1630 and 1640 provides exceptional performance in both modern diesel engines as well as older models. The key benefits include:
