15W-40 Full Protection

The original Delvac™ was one of the world's first diesel engine oils and patented in 1925. Since then, Delvac has led the way in lubrication technology and innvovation to meet the ever-evolving needs of the global transport industry.

Today, while the Delvac Modern™ family can trace its heritage back to 1925, its advanced formulation and performance is designed for engines that early engineers could only have dreamed of. With enhanced protection from bumper to bumper, these heavy duty lubricants have enabled both on and off-highway fleet businesses to grow, thrive and drive into the future.

Whichever product from the Delvac Modern range of high performance diesel engine oils is right for your needs, they all offer:

  • Long oil drain interval to save service downtime and costs
  • High temperature protection for today's heavy duty, high performance engines
  • Advanced engine performance and protection in both hot and cold temperatures
  • Wear protection to extend long engine life

Mobil Delvac Modern 15W-40 Full Protection

  • Formulated for the most demanding on and off-highway applications to help extend engine life. Delivers an outstanding performance in contemporary high-output, low-emission engines as well as in older engines.
  • Pack size: 1L, 5L, 20L, 208L & Bulk.
 

Features and benefits

  • Superior soot viscosity to help maintain engine efficiency and long life of both engine and oil.
  • Outstanding thermal and oxidative stability to reduce sludge build up and deposits .
  • Maintains viscosity at severe high temperatures for greater wear protection and long engine life.
  • Fast oil flow at low temperatures for rapid protection and reduced wear on cold engine start-up.

Mobil Delvac Range FAQs

It’s true that Mobil Delvac can help to extend the life of your commercial vehicle engine.

However, the actual life of an engine prior to overhaul depends on many variables from oil-drain intervals and maintenance practices to your driving habits and the load carried.

But using Mobil Delvac engine oils will certainly help keep the engine-life odds in your favour.

Both in the engine and driveline, it can.

So you have two things to consider: A multigrade product tends to provide better fuel economy than a monograde (e.g., a 5W-40 is better than a 40 grade) and lower viscosity products tend to provide better fuel economy than higher viscosity products (e.g., a 5W-30 provides better fuel economy than both a 10W-30 and a 15W-40).

As equipment ages, deposits and wear accumulate, resulting in a decrease in equipment efficiency. Mobil Delvac™ lubricants are able to protect the engine against deposit formation and wear, and resist soot-induced and oxidative viscosity thickening, allowing the equipment to maintain fuel economy throughout its life, making Mobil Delvac a great choice for diesel engine oil.

Many truck engines idle for very prolonged periods during cold winter temperature conditions to allow for warm-up and to keep the cab warm.

Prolonged idling will reduce engine life and also waste fuel. Engines operate cooler while idling, and during long idle periods in winter's cold temperatures, moisture in the intake air can condense in the engine crankcase and produce corrosive sulphuric acid, which can attack soft bearing alloys.

Long idling also contributes to increased soot and combustion contaminants, which will shorten the engine oil's life prematurely and can lead to excessive piston deposits, sludge formation and detrimental viscosity effects.
