After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

Your 1990 C2500’s oil should be changed according to GMC’s recommended oil change intervals. See mileage and month specifics in the above table. No matter the mileage, your C2500 may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, drive in dusty areas, enjoy off-roading, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your GMC C2500. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.

1990 GMC C2500 Oil Change Q&A

  • Why check the motor oil level in my GMC C2500? Engine oil is a lubricant for the moving parts in your engine. If your oil reservoir is low or empty, engine parts can grind together, generate excess heat, and cause your GMC C2500 engine to fail. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my GMC C2500 oil at home? First off, changing your own oil isn’t as easy as you’d think. It requires special tools and old oil must be disposed of properly. 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 C2500 exhaust smoke grayish or blue? You could have an oil leak and have a case of burning oil. It may be time for a pro to take a look. The leak could be caused by several issues like leaking valve seals, fried piston rings, or damaged cylinder walls.
