The check engine light in a 2000 Dodge Grand Caravan will not necessarily come on if you need an oil change. The check engine light is typically triggered by a problem with the vehicle's emissions system, sensors, or other critical components. While low oil levels or poor oil quality can affect engine performance and potentially contribute to emissions issues, they are not the primary factors that cause the check engine light to illuminate.
Instead, regular oil changes are essential for maintaining the health and longevity of your vehicle's engine. Neglecting oil changes can lead to various engine problems, including increased wear and tear, reduced performance, and potential damage to engine components. To avoid these issues and ensure optimal engine operation, it's crucial to follow the vehicle's recommended oil change intervals as specified in the owner's manual.
