How often should the Chevrolet Equinox III (L1U) have an oil change?

The factory schedule calls for an engine-oil & filter change every 7,500 mi · 12,000 km or 12 mo under normal driving, and every 4,000 mi · 6,400 km under severe duty, verified from the owner's manual.

Normal vs severe service — which applies to me?

Severe (or 'special') duty applies to short trips, extreme cold/heat, dusty or stop-and-go driving, towing, or extended idling — most real-world use is closer to severe than many owners assume. When in doubt, follow the severe-duty intervals.
