Synthetic Emission System Protection Diesel Engine Oil

Product Description

Mobil Delvac XHP ESP S 10W-40 is a synthetic extra 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 new advanced additive system has been expertly engineered to help towards long engine life2 and maintain the efficiency of emission reduction systems including the Diesel Particulate Filter (DPF). Its specifications and approvals allow Mobil Delvac XHP ESP S 10W-40 to target mixed fleet applications.


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 XHP ESP S 10W-40 delivers exceptional performance, long drain interval capability and protection of exhaust systems including those fitted with Diesel Particulate Filters (DPF). The key benefits include:



Advantages and Potential Benefits

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

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

Stay-in-grade shear stability. Very low volatility

Low ash, sulfur and phosphorous levels

Excellent low temperature properties

Provides capability for long drain intervals

Helps to protect against ring sticking

Helps to towards long engine life2

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

Helps to protect exhaust systems devices like those fitted with DPF

Helps to improve pumpability and oil circulation


2 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.
