Mobil Delvac 1™ 5W-40

Mobil Delvac 1  5W-40 is a fully synthetic supreme performance heavy duty diesel engine oil that helps extend engine life while providing long drain capability and fuel economy for modern diesel engines operating in severe applications. Mobil Delvac 1™ utilizes state-of-the-art technology to deliver exceptional performance in modern low emission engines, including refrigerated units, as well as older, well-maintained engines.

Mobil Delvac 1 5W-40 is recommended for use in a wide range of heavy-duty applications and operating environments found in the on-road transport and off-road mining, construction, and agricultural industries. Mobil Delvac 1 also meets the requirements of the API SL specification for gasoline engines used in mixed fleets.

The unequalled performance of Mobil Delvac 1 5W-40 is the result of extensive cooperative development work with major equipment builders and application of the latest lubrication technology. As a result, this product meets or exceeds the requirements of the latest API, ACEA, JASO, and Global industry specifications for diesel engine oils, as well as the requirements of virtually all major American, European, and Japanese engine manufacturers.

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 Delvac 1 5W-40 maintains outstanding performance at significantly higher temperatures than other high performance diesel engine oils.  It is also fully compatible with conventional oils. The key benefits include:

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

 

Mobil Delvac 1 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.
