How often should I change the oil in my 2000 GMC Cab & Chassis?

Can I use synthetic oil in my 2000 GMC Cab & Chassis?

Yes. 5W-30 is widely available as a full synthetic, and synthetic is safe (often recommended) for the 2000 GMC Cab & Chassis. What matters most is matching the factory viscosity and specification, then changing the oil and filter on schedule.
