MOBIL DELVAC HD 10W-40

Heavy Duty Diesel Engine Oil

Mobil Delvac HD 10W-40 is a semi-synthetic high performance diesel engine oil engineered to provide lubrication to modern, high performance, low emissions engines used in severe applications. This engine oil is designed using high performance base oils which provide excellent low temperature fluidity, high temperature viscosity retention and volatility control. The proven advanced additive system has been expertly engineered to help towards long engine life and maintain the efficiency of emission reduction systems including the Diesel Particulate Filter (DPF).

Features and Benefits

High output, low emission engines significantly increase demands on engine lubricants. Tighter engine design, use of inter-coolers, and turbochargers increase thermal stresses on the lubricant. Low emission engine technologies such as higher fuel injection pressure, retarded timing and aftertreatment devices all require improved oil performance in areas such as oxidation stability, soot dispersancy, volatility and compatibility with aftertreatment devices. The advanced technology in Mobil Delvac HD 10W-40 delivers high performance, long drain interval capability and protection of exhaust systems including those fitted with Diesel Particulate Filters (DPF). The key benefits include:

Features

Advantages and Potential Benefits

Protection against oil thickening, high temperature deposits, sludge build-up and, oil degradation

Provides capability for long drain intervals
Helps to protect against ring sticking

Excellent anti-wear, anti-scuff properties and bore polishing and corrosion protection.

Helps towards long engine life1

Stay-in-grade shear stability. Very low volatility

Helps to reduce viscosity breakdown and oil consumption under heavy duty, high temperature operating conditions

Low ash, sulfur and phosphorous levels

Helps to protect exhaust systems devices like those fitted with DPF

Good low temperature properties

Helps to improve pumpability and oil circulation

1 Well formulated oils, like Mobil Delvac, that meet or exceed industry or OEM specifications, can help protect engines. Consult OEM for optimum fluid selection. Actual results may vary depending on OEM requirements, type of engine and its maintenance, application and service conditions, and prior lubricant used.

Applications2

  • Heavy Duty Diesel Engines including Euro V/VI Modern Low Emissions Vehicles, Utilizing Technologies such as Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR), Continuously Regenerating Traps (CRT), Diesel Oxidation Catalysts (DOC) and Exhaust Gas Recirculation (EGR)
  • Heavy Duty Diesel Engines using low sulfur diesel fuels and many biodiesel fuel formulations
  • Naturally Aspirated and Turbo-Charged Diesel Powered Equipment
