Mobil Delvac 1 5W40

Mobil Delvac 1™ 5W-40

Many modern, low emission diesel engines generate more soot and operate at higher temperatures than older engines. This significantly increases the need for high performance lubricants. Current tighter engine designs reduce oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Top piston rings are located higher, bringing the oil film closer to the combustion chamber and exposing the lubricant to severe thermal stresses. Mobil Delvac 1 5W-40 maintains outstanding performance at high temperatures. It is also fully compatible with conventional oils. The key benefits include:

  • Meets or exceeds demanding specifications of major OEMs: One engine oil for mixed fleet operations
  • Outstanding thermal and oxidation stability: Control of low temperature sludge build-up and high temperature deposits
  • Low volatility, excellent wear and bore polish control: Good oil consumption control
  • Expertly formulated low viscosity formulation: Fuel economy potential (1)
  • Exceptional low temperature pumpability: Easier engine start-up and reduced wear
  • Good resistance to corrosion: Helps towards long life of critical wear surfaces
  • Long drain capability: Help towards operational efficiency and overall cost control
  • Component compatibility: Long gasket and seal life, extended service intervals
