An oil change is appropriate when the oil-change reminder appears or when mileage has passed since the last service. Oil loses additive performance and its ability to carry heat and debris before it necessarily looks dirty. Heavy towing, extensive stop-and-go driving, dusty conditions, and repeated short trips can place additional demands on engine oil.

• Watch for the oil-change reminder light
• Check for dark or low oil on the dipstick
• Pay attention to a louder or ticking engine at startup
