Synthetic oil lasts longer (often 7,500-10,000 miles or more), performs better in extreme temperatures, and provides superior engine protection. Conventional oil is less expensive but needs more frequent changes (typically every 3,000-5,000 miles). Many newer Chevrolet vehicles are factory-filled with synthetic or high-quality blends.

Your owner's manual specifies which type is recommended for your vehicle. Castle Chevrolet North's Service Department uses genuine Chevrolet oils matched to your model's requirements-ensuring optimal performance and warranty protection.
