GMC recommends having your 1991 GMC R1500 Suburban’s motor oil changed at regular intervals. Check out mileage and month info for your R1500 Suburban in the above table. No matter the mileage, your R1500 Suburban 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 car, 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, frequent dusty roads, go off-roading a lot, or go at low speeds on long distance trips. More frequent oil changes generally won't harm your GMC R1500 Suburban. 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.

1991 GMC R1500 Suburban Oil Change Questions

  • Should I check my GMC R1500 Suburban motor oil level? 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 R1500 Suburban engine failure. That’s why you should check your oil and get it changed regularly.
  • Can I change my GMC R1500 Suburban oil at home? Changing your own oil isn't as convenient as you might think. It requires special tools and old oil must be disposed of properly. Getting a professional oil change reduces the risk of something going wrong during the service, but also help your car perform down the road.
  • Why is my GMC R1500 Suburban exhaust smoke grayish or blue? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. A leak can be caused by a variety of issues including faulty valve seals, fried piston rings, or old cylinder walls.
  • Who can change the oil on my GMC R1500 Suburban? You can count on Firestone Complete Auto Care for your GMC R1500 Suburban oil change, oil filter replacement, oil leak diagnostics, and more! Our expert technicians will even advise the right oil for your vehicle.
  • Why is the oil light on in my GMC R1500 Suburban? If you’re overdue for an oil change, it might trigger your GMC R1500 Suburban oil change reminder light. If the oil pressure light is illuminated, it could be due to low engine oil, a failing oil pump, a malfunctioning oil pressure sensor, or a clogged oil filter.
  • Do I need to change my R1500 Suburban's oil filter when I get an oil change? Every time you change the oil in your GMC R1500 Suburban, you should also replace the oil filter. Otherwise, you risk contaminating your brand-new oil with the dirt and debris built up in your old filter.
