Diesel fuel is a type of distillate fuel that is essentially produced from crude oil which gives diesel engines slower cylinder wear than gasoline engines. Within a matter of just four weeks after being refined diesel fuel can degrade as much as 26-percent. The first is that a diesel engine needs to be properly sized in the first place.
Mechanics says that if maintained properly a diesel engine would last for around 30 years.
But diesel engines can continuously run for an impressive 1000000-1500000 miles before needing any major work. How long will a diesel engine last. All of these issues and more will make a diesel engine last 1000000 miles or more versus 200000 if you are lucky with a gas powered engine but each motor is different.
