What is the lifespan of a diesel engine?
Diesel engines are robust machines that have longer lifespans than you might expect. The lifespan of an average diesel engine is anywhere from 400,000 miles to 1,000,000 miles, while the average lifespan of a gas engine is around 200,000 miles. That being said, some recent studies show that BMW models can last up to 200,000 to 250,000 miles, with an average lifespan of at least 15 years. On the other hand, Mercedes-Benz vehicles tend to last up to 150,000 to 200,000 miles with an average lifespan of over 10 years.
