Mobil 1 122253 Turbo Diesel Truck Full Syn Motor Oil 5W-40 - Case (6 Quarts)

Helps extend engine life for modern diesel engines even in severe applications Mobil 1™ Turbo Diesel Truck 5W-40 full synthetic performance heavy-duty diesel engine oil helps extend engine life while providing long drain capability and fuel economy benefits for modern diesel engines operating in severe applications. One engine oil for mixed fleet operations Mobil 1 Turbo Diesel Truck 5W-40 engine oil is recommended for use in all super-high-performance diesel applications, including modern low-emission engine designs with Exhaust Gas Recirculation (EGR). These applications include: On-highway engines operating in both high-speed/high-load and stop-and-go conditions Off-highway engines operating in severe low-speed/heavy-load conditions Virtually all diesel-powered equipment from American, European and Japanese equipment builders High-performance gasoline engines and mixed fleets Refrigeration units Increases operating efficiency, extends service intervals and lowers costs Many modern, low-emission diesel engines generate more soot and operate at higher temperatures than older engines. This significantly increases the need for supreme-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 1 Turbo Diesel Truck 5W-40 engine oil helps maintain outstanding performance at significantly higher temperatures than other high-performance diesel engine oils. It is also fully compatible with conventional oils. Its long drain capability helps increase operating efficiency and lower overall cost.
