      Mobil 1 Turbo Diesel Truck 5W-40 is a fully synthetic performance heavy duty diesel engine oil that helps to extend engine life while providing long drain capability and fuel economy for modern diesel engines operating in severe applications. Utilizes state-of-the-art technology to help deliver exceptional performance in modern low emission engines, including refrigerated units, as well as older, well-maintained engines. Its uniform synthetic oil molecules reduce friction, helping to prevent high-temperature deposits and low-temperature sludge buildup. It also helps prevent engine scuffing and bore polishing at high temperatures. Provides excellent low-temperature pumpability, supporting easier engine starting and helping to reduce wear. Helps control oxidation to prevent oil breakdown, and is recommended for use in a wide range of light-duty applications such as turbo diesel pick-up trucks, as well as, heavy-duty applications and operating environments found in the on-road transport and off-road mining, construction, and agricultural industries. Meets the API SM specification for gasoline engines used in mixed fleets. The performance of Mobil 1 Turbo Diesel Truck 5W-40 is the result of extensive cooperative development work with major equipment builders and application of the latest lubrication technology.
