Features and Benefits

Modern high output diesel engines run hotter than older engines which significantly increases the demands on engine 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 where temperatures increase thermal stress on the lubricant. Mobil Delvac Ultra 5W-40 Ultimate Defense helps to protect the engine under severe operating conditions. It is also fully compatible with conventional mineral oils. The key benefits include:
