* Maintenance: Regular oil changes, proper cooling system maintenance, and timely repairs are crucial. Neglecting maintenance significantly reduces engine life.
* Driving habits: Aggressive driving, frequent high-RPM operation, and short trips put more stress on the engine.
* Modifications: Aftermarket modifications, especially those increasing power output, can shorten the engine's lifespan if not done correctly.
* Environmental conditions: Extreme temperatures and harsh weather can accelerate wear and tear.
* Quality of parts: Using lower-quality replacement parts can lead to premature failure.
While some engines might reach 200,000 miles or more with meticulous care, others could fail much sooner due to any of the factors above. It's not uncommon to see these engines reach 150,000 miles, but exceeding that often depends on the owner's dedication to maintenance. There's no guaranteed mileage number.
