Five Diesel Engines That Refuse to Quit

Diesel engines are known for their robustness and fuel efficiency, but some stand out for their incredible longevity. SlashGear has highlighted five diesel engines that have earned a reputation for lasting hundreds of thousands of miles, often outliving the vehicles they power.

Among these legendary powerplants are the Cummins 5.9L inline-six, found in Dodge Ram trucks, which is celebrated for its simplicity and durability. The Ford 7.3L Power Stroke V8, used in Super Duty trucks from the late 1990s to early 2000s, is another stalwart, often reaching 500,000 miles with proper care. The Duramax 6.6L V8, a General Motors staple, combines power with longevity, while the Mercedes-Benz OM617 five-cylinder, used in older models, is a favorite among enthusiasts for its bulletproof design. Finally, the Toyota 1HD-FTE inline-six, though less common in the U.S., is revered globally for its dependability in Land Cruisers.

These engines share traits like robust construction, simple designs, and ease of maintenance, which contribute to their extended lifespans. While modern diesels are more complex, these classics remain benchmarks for durability, proving that sometimes simpler is better.
