What maintenance practice can improve the life of a diesel engine?

Regular oil changes and oil filter replacements are critical maintenance practices that significantly enhance the lifespan and performance of a diesel engine. Over time, engine oil breaks down due to heat, contamination, and the accumulation of particulates. Fresh oil provides better lubrication, reduces friction, and helps to prevent wear on engine components. Additionally, the oil filter plays a vital role in removing harmful particles and contaminants from the oil. If oil changes are neglected, it can lead to sludge buildup and reduced lubrication efficiency, potentially causing severe engine damage.

In contrast, using high-sulfur fuel can result in increased emissions and potential damage to engine components, while neglecting air filter replacements can lead to reduced engine efficiency due to restricted airflow. Running the engine at maximum RPM constantly can cause excessive wear and tear, leading to a shortened engine lifespan. Thus, maintaining an effective oil change schedule and regularly replacing the oil filter are fundamental in ensuring the optimal operation and longevity of a diesel engine.
