Factors affecting lifespan include:
* Maintenance: Regular oil changes, filter replacements, and other preventative maintenance are crucial. Neglecting maintenance significantly shortens the engine's life.
* Driving habits: Aggressive driving, excessive idling, and towing heavy loads put extra stress on the engine.
* Operating conditions: Frequent extreme temperatures (very hot or very cold) can also affect longevity.
* Specific engine model and year: Different Cummins engines have different designs and strengths, affecting their durability.
* Modifications: Modifications, while potentially improving performance, can also impact the engine's lifespan if not done properly.
In short, while many Dodge Cummins engines achieve remarkably high mileage, it's more accurate to say they are capable of lasting a very long time rather than giving a specific mileage or year figure. Proper maintenance is the key to maximizing their lifespan.
