Mobil Delvac Legend™ 1640
Monograde Heavy Duty Engine Oil
Features and Benefits
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 under such extreme conditions. Mobil Delvac Legend 1640 is designed to provide exceptional performance in diesel engines. The key benefits include:
