Five Legendary Engines That Have Proven They Can Go More Than 300,000 Miles

Among car enthusiasts, there's a long-standing fascination with vehicles that seem to run forever. While no engine is truly indestructible, a handful of powerplants from the 1980s, 1990s, and early 2000s have built legendary reputations for reliability. With proper maintenance, many have logged well over 300,000 miles before requiring a major engine rebuild.

1. BMW M57

BMW engines have earned numerous international awards over the years, but performance doesn't always guarantee long-term durability. The inline-six BMW M57 diesel is one of the exceptions, combining strong performance with an outstanding reputation for longevity.

Introduced in 1998, the M57 was offered in 2.5-liter, 2.9-liter, and 3.0-liter versions. It powered a wide range of BMW models, including the 3 Series, 5 Series, 7 Series, X3, X5, X6, and X7, as well as certain Range Rover models.

While minor repairs aren't uncommon, a properly maintained M57 can often exceed 300,000 miles before needing major engine work. Routine maintenance and quality replacement parts are key to achieving that lifespan.

Other highly regarded BMW engines include the V8 M60 and the inline-six M30 and M50.

2. Toyota 3S-FE

The Toyota 3S-FE is a naturally aspirated 2.0-liter inline-four gasoline engine that was produced from 1986 through 2002. Depending on the application, it produced between 128 and 140 horsepower and became known for its straightforward design, impressive reliability, and ability to tolerate less-than-perfect maintenance.

Found in numerous Toyota sedans, hatchbacks, and SUVs, the 3S-FE has earned a reputation for requiring few repairs and often reaching more than 300,000 miles before a major overhaul.

Toyota's inline-six 1JZ-GE and 2JZ-GE engines have also become famous for their durability, particularly in models such as the Mark II, Chaser, and Crown.

3. Mercedes-Benz OM602

Mercedes-Benz's five-cylinder OM602 diesel is widely regarded as one of the brand's most durable engines. It powered iconic models including the 190 (W201), E-Class (W124 and W210), G-Class, and Sprinter, and was available in 2.5-liter and 2.9-liter versions.

With regular maintenance, many vehicles equipped with the OM602 have surpassed 300,000 miles, while some have reportedly reached more than 600,000 miles. Much of that longevity comes from its simple engineering, two valves per cylinder, and a robust Bosch inline fuel injection pump.

4. Mitsubishi 4G63

Another legendary Japanese engine is Mitsubishi's 4G63. Introduced in the early 1980s, the 2.0-liter inline-four remained in production for decades and powered a wide variety of Mitsubishi vehicles.

Over the years, the engine evolved from a single-overhead-cam design to a dual-overhead-cam layout, while carburetors eventually gave way to electronic fuel injection. Early naturally aspirated versions are especially well known for their exceptional durability and are often considered capable of extremely high mileage.

5. Honda D15 and D16

Honda has long been recognized for building dependable engines, and its D-Series family became one of the company's biggest success stories. Produced throughout the 1980s and 1990s, these engines ranged from 1.2 to 1.7 liters in displacement.

Among them, the D15 and D16 stand out for their longevity. With proper maintenance, many examples have accumulated 220,000 to more than 300,000 miles before requiring major engine work. Their durable design also allows many of them to continue delivering reliable service even after a complete rebuild.
