1. Gasoline engines: On average, gasoline engines in passenger vehicles can last anywhere from 150,000 to 200,000 miles (241,400 to 321,869 kilometers) under normal usage and proper maintenance. Some well-maintained gasoline engines may even surpass 300,000 miles (482,802 kilometers).
2. Diesel engines: Diesel engines are known for their durability and longevity. In automotive applications, they can typically last upwards of 200,000 to 300,000 miles (321,869 to 482,802 kilometers). Diesel engines used in commercial vehicles, such as trucks and buses, may reach even higher mileages if properly maintained.
3. Heavy-duty engines: Internal combustion engines used in agricultural, construction, marine, or industrial applications often have extended lifespans. These engines are built to withstand heavy workloads and challenging operating conditions and can last several thousand hours, equivalent to hundreds of thousands of miles in vehicles.
It's worth noting that these figures are estimates and individual engine longevity can vary significantly. Proper maintenance, including regular oil changes, fluid replacements, belt and hose inspections, and adherence to the manufacturer's recommended service intervals, plays a crucial role in extending the lifespan of an internal combustion engine. Harsh operating conditions, high mileage accumulation, towing heavy loads, and neglecting maintenance can decrease engine longevity.
