How many miles can a diesel engine run?

Diesel engines are built to last. While gas engines may run for 200,000 miles, a well-maintained diesel engine can run for 1,000,000 miles or more. A diesel engine’s life span depends on the load’s weight, the fuel type and the consistent maintenance quality.

Diesel Engine Maintenance Tips

Regular maintenance is critical for a safe haul with a diesel engine that lasts. Here are a few key diesel engine maintenance tips to keep your engine humming:

Oil Changes

Since diesel engines produce more contaminants than gasoline engines, it’s important to change your oil more to keep the engine parts lubricated and prevent damage from buildup.

Fuel Filter Changes

Changing your fuel filter is an important part of diesel engine maintenance. It protects the engine from impurities and water that damage the injectors irreparably if left unchecked.

Coolant Flushes

Since diesel engines function at high temperatures, cooling is essential. Flushing the coolant can help prevent overheating, which is essential for a diesel engine’s long lifespan.

Regular Inspection

For operators who want their diesel engine to last, regular inspections should not be ignored. Regular maintenance helps avoid costly repairs, before they become larger problems.
