Which of the following factors can affect how often you should have your oil changed?

Driving conditions significantly influence how often you should change your oil. Various factors related to driving conditions can affect engine performance and oil degradation, such as stop-and-go traffic, extreme temperatures, towing heavy loads, or driving on rough terrain. For instance, frequent short trips where the engine doesn't reach optimal operating temperature can lead to moisture buildup in the oil, necessitating more frequent changes.

In contrast, other options do not have a direct impact on oil change intervals. For example, the color of a vehicle does not affect its engine performance or oil quality. While the make of the vehicle can provide general recommendations for maintenance schedules, it is not the sole determining factor; rather, it needs to be considered alongside driving habits. Similarly, the type of tires may influence vehicle handling and safety but does not influence the engine oil's condition or its need for replacement.
