What is the secret of diesel's longevity?

By Sandra Zablotna - Thursday 20 June 2024


Diesel engines are known for their durability and efficiency, said to outlast petrol engines. See below to find out why.


Diesel engines are favoured for high-kilometer travel and load-carrying applications due to their durability and efficiency. Diesel vehicles like the Toyota LandCruiser, Toyota Hilux, Isuzu D-Max, Mitsubishi Pajero Sport often exceed 500,000km without major issues, whereas petrol cars over 300,000km frequently require engine replacements. Diesel engines produce more torque at lower revs, reducing mechanical stress and wear. Their simpler design, lacking an external ignition source, also contributes to their longevity. However, diesel engines are noisier, create more vibrations, and require meticulous maintenance due to emission components and the potential for costly failures.

In comparison, petrol engines operate at higher revs, leading to increased wear and shorter lifespans. Despite their smoother operation and lower maintenance costs, petrol engines often don't last as long as their diesel counterparts.

Diesel cars are popular due to their robust performance, superior fuel efficiency, and ability to handle heavy loads, making them ideal for demanding environments and extensive travel. However, it's essential to choose a car that meets your specific needs, considering factors like driving habits, load requirements, and maintenance capabilities.
