Mobil Plus Full Synthetic 5W-40 Heavy-Duty Motor Oil is made with high-quality synthetic oils and advanced additives. It’s perfect for modern diesel engines, including those made from 2017 onwards, and also works well with older models.

 

This oil helps protect important engine parts, including emission systems like diesel particulate filters (DPFs). It keeps your engine running clean and strong by fighting wear, reducing deposits, and staying stable in extreme temperatures.

 

It meets and exceeds top industry standards like API CK-4/SN, and also covers older specs like CJ-4 and CI-4. If your fuel has more than 15ppm of sulphur, check your engine’s service guide for proper oil change intervals.


Benefit:

  • Forms a stronger, more stable oil film that reduces engine wear, especially in high-load, high-temperature conditions—ideal for performance or long-life engines.

 

  • Flows faster than conventional oils at low temperatures (thanks to its 5W rating), providing instant lubrication during startup, which reduces cold-start engine wear.

 

  • Withstands extreme heat without breaking down, maintaining its viscosity and protection even under high-performance driving or towing.

 

  • Advanced full synthetic base oils and detergents help prevent sludge, varnish, and carbon deposits, keeping internal engine components cleaner for longer.

 

  • Fully synthetic 5W-40 is engineered for turbocharged and direct-injection engines, offering better protection against turbo heat, LSPI (low-speed pre-ignition), and carbon build-up.

 

  • Greater oxidation resistance means the oil lasts longer before degrading, allowing for longer oil change intervals (when approved by the vehicle manufacturer).

 

  • Many full synthetic 5W-40 oils are formulated with low-SAPS technology, which helps protect catalytic converters and diesel particulate filters (DPFs), supporting compliance with modern emissions standards.

 

  • Maintains its viscosity in both cold and hot conditions better than conventional oil, ensuring consistent lubrication and protection year-round.


Always check your car’s manual to find the right engine oil, it tells you exactly what your engine needs to run smooth and stay protected.
