GMC recommends changing your 1991 G1500’s oil at regular intervals. Check out mileage and month info for your G1500 in the above table. Your G1500 may need an oil change right away if your check engine/oil change light is on, you hear knock knock knock coming from the engine, smell oil inside the car, 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, adventure off-road, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your GMC G1500. 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.

Oil Change Q&A for Your 1991 GMC G1500

  • What can low oil do to my GMC G1500 engine? Motor oil lubricates important engine parts. If your oil reservoir is low or empty, these parts can grind together, generate excess heat, and cause your GMC G1500 engine to fail. 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 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 G1500 spewing blue or gray exhaust smoke? There could be an oil leak and your engine is burning oil. Time to have a qualified technician check things out. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or old cylinder walls.
