How Often to Get 1990 GMC C1500 Oil Changes

Not sure how or where to get your GMC C1500’s oil changed? Turn to Firestone Complete Auto Care! We are experts in car care — not just tires. We know all about motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

GMC recommends changing your 1990 C1500’s oil at regular intervals. See mileage and month specifics in the above table. No matter the mileage, your C1500 may need its oil changed ASAP if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, frequent dusty roads, go off-roading a lot, or go long distances at low speeds. More frequent oil changes generally won't harm your GMC C1500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

1990 GMC C1500 Oil Change Q&A

  • Should I check my GMC C1500 motor oil level? Engine oil lubricates moving parts in your engine. If your oil reservoir is low or empty, these parts can grind together, generate excess heat, and cause your C1500’s engine to fail. That’s why you should check your oil and get it changed regularly.
  • How hard is it to change GMC C1500 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 professionally changed reduces the chances of something going wrong with the oil change, but also help your car perform down the road.
  • Why is my GMC C1500 exhaust smoke grayish or blue? Your engine could be burning oil due to a leak. Looks like it’s time for a professional to take a look. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or old cylinder walls.
