Your 1999 C1500’s oil should be changed according to GMC’s recommended oil change intervals. Check out mileage and month info for your C1500 in the above table. Outside of GMC-recommended oil change intervals, your C1500 may need an oil change if your check engine light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, drive in dusty terrain, enjoy off-roading, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your GMC C1500. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

1999 GMC C1500 Oil Change Q&A

  • Why check the motor oil level in my GMC C1500? Engine oil is a lubricant for the moving parts in your engine. If your oil reservoir is low or empty, these components can grind against each other, generate excess heat, and eventually lead to GMC C1500 engine failure. That’s why you should check your oil and get it changed regularly.
  • Can I change my GMC oil on my own? Changing engine oil at home isn’t as simple as it’s made out to be. You’ll have to figure out how to properly dispose of the oil and buy special tools. Having your oil changed professionally can not only reduce the risk of something going wrong during the service, but also with your vehicle down the road.
  • Why is my GMC exhaust smoke gray or blue? You could have an oil leak and have a case of burning oil. Time to have a qualified technician check things out. A leak can be caused by a variety of issues including faulty valve seals, fried piston rings, or old cylinder walls.
