Features

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 helps to maintain outstanding performance at significantly higher temperatures than other high performance diesel engine oils. It is also fully compatible with conventional oils. The key potential benefits include:

Features Advantages and Potential Benefits
Meets or exceeds demanding specifications of major OEMs One engine oil for mixed fleet operations
Outstanding thermal and oxidation stability Helps to reduce low temperature sludge build-up and high temperature deposits
Enhanced film strength at high temperatures Helps to reduce engine scuffing and bore polishing
Inherent stay-in-grade shear stability Wear protection and reduced oil consumption; helps to maintain viscosity in severe, high temperature service
Advanced formulation and viscometrics Aids fuel economy
Low volatility Helps to control oil consumption
Exceptional low temperature pumpability Easy engine start-up and helps to reduce wear
Enhanced TBN quality reserve Helps to deposit control and extended drain capability
Outstanding resistance to corrosion Helps to extend life of critical wear surfaces
Long drain capability Helps to increase operating efficiency and lower overall cost
Component compatibility Long gasket and seal life, helps to extend service intervals

Applications

Mobil 1 Turbo Diesel Truck 5W-40 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 the following:

  • 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

Will this work on my Mercedes if it calls for “requirements of Mercedes Benz MB 229.51”?

BEST ANSWER: I sent you an email, I would need more information on your vehicle, I do not see that spec on the product data sheet. I do, however, see that spec on the Mobil 1 ESP product but I would like to double check your vehicle information.

Mobil 1 ESP oils help prolong the life and maintain the efficiency of emission systems in both diesel- and gasoline-powered automobiles. They are formulated to be fully compatible with passenger car diesels that have the latest diesel particulate filters (DPFs) and gasoline catalytic converters (CATs).
