How often should I change the oil in my 2013 Chevrolet Silverado 3500 HD?

Most 2013 Chevrolet Silverado 3500 HD owners follow a 5,000–7,500 mile interval with conventional oil, or up to 10,000 miles with full synthetic. Always check the oil life monitor if equipped, and consult your owner's manual — Chevrolet recommends intervals based on driving conditions, not just mileage.

Can I use synthetic oil in my 2013 Chevrolet Silverado 3500 HD?

Yes. 5W-30 is widely available as a full synthetic, and synthetic is safe (often recommended) for the 2013 Chevrolet Silverado 3500 HD. What matters most is matching the factory viscosity and specification, then changing the oil and filter on schedule.
