What is a common procedure for changing a truck's oil?

The procedure for changing a truck's oil involves several key steps to ensure that the engine remains lubricated and functions properly. The correct answer details the process of first draining the old oil, which removes contaminants and prevents them from circulating in the engine. Following this, the oil filter is replaced. This is crucial because the oil filter removes impurities from the engine oil as it circulates. Finally, refilling the engine with new oil replenishes the lubrication needed for the engine components, ensuring smooth operation and preventing wear.

This comprehensive approach not only extends the life of the engine but also maximizes its performance. Simply draining old oil and refilling without changing the oil filter would leave the contaminants in the system, which could lead to engine damage over time. Similarly, unrelated tasks such as changing the battery, coolant, or tires do not pertain to the oil change procedure, highlighting the importance of understanding specific maintenance tasks and their implications for vehicle health.
