The lifespan of a diesel engine relies on different factors. It's generally estimated that a diesel engine can run without major issues for approximately 1.6-2.4 million kms. This means a well-maintained diesel engine could last for over 30 years.
Does a diesel engine outlast a petrol engine?
For comparison, a car's petrol engine typically lasts around 320,000 kms before requiring significant maintenance or replacement, which is significantly less than the 1.6-2.4 million kms of a diesel engine. The diesel engine's enhanced durability can be attributed to the following factors:
- The comprehensive design of the engine.
- The type of fuel utilized.
- The vehicles equipped with diesel engines are often constructed with more robust components.
- The self-cooling capability of the engine.
