Diesel engine - lifespan

Question

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:

1. The comprehensive design of the engine.
2. The type of fuel utilized.
3. The vehicles equipped with diesel engines are often constructed with more robust components.
4. The self-cooling capability of the engine.
