Why do diesel engines last longer?

Someone recommended that I buy a diesel car because the engines last longer. Why is this the case?

An engine that lasts longer is definitely a plus! Diesel engines last longer thanks to their design, which has higher compression ratios and higher cylinder pressures than traditional
gas engines
.
Here are a couple of other reasons why a diesel engine lasts longer:
  • Diesel gas is produced from crude oil, giving diesel engines slower cylinder wear
  • Lower RPMs
While the average gasoline engine might last around 200,000 miles before needing an overhaul, a diesel engine could make it to about a million miles before needing any serious work.
It doesn’t matter if you have a diesel or gas engine, you should never overpay for
car insurance
