Mobil DelvacTM 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).
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:
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
- 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.
- On-Highway Short-Haul and Long-Haul Trucks and Buses.
