How Often to Get 1990 GMC R2500 Suburban Oil Changes

Looking for oil change recommendations for your 1990 GMC R2500 Suburban? Turn to Firestone Complete Auto Care! We are experts in car care — not just tires.

GMC recommends having your 1990 GMC R2500 Suburban’s motor oil changed at regular intervals. See mileage and month specifics in the above table. Outside of GMC-recommended oil change intervals, your R2500 Suburban may need an oil change if your check engine 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, enjoy off-roading, or go at low speeds on long distance trips. More frequent oil changes generally won't harm your GMC R2500 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.

1990 GMC R2500 Suburban Oil Change Questions

  • Why check the motor oil level in my GMC R2500 Suburban? Motor oil lubricates important engine parts. If your oil reservoir is low or empty, engine parts can grind together, generate excess heat, and cause your R2500 Suburban’s engine to fail. That’s why you should check your oil and get it changed regularly.
  • Can I change my GMC R2500 Suburban oil at home? Changing engine oil at home isn’t as simple as it’s made out to be. 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 with your vehicle down the road.
  • Why is my GMC exhaust smoke gray 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, fried piston rings, or worn cylinder walls.
  • Who can change the oil on my GMC R2500 Suburban? Turn to Firestone Complete Auto Care for GMC R2500 Suburban oil changes. In addition to changing your oil, our experienced technicians also perform oil filter replacements, troubleshoot oil leaks, and suggest the correct oil to help keep your engine performing its best.
  • Why is my GMC R2500 Suburban oil light illuminated? The oil change light in your GMC R2500 Suburban could be triggered by an overdue oil change. However, if the oil pressure light is on, you may be dealing with low engine oil, a failing oil pump, a clogged oil filter, or a malfunctioning oil pressure sensor.
  • Does my R2500 Suburban's oil filter need to be changed during my oil change? You should replace your GMC R2500 Suburban during each oil change. The filter captures debris and contaminants to help keep your oil clean, which means the filter gets dirty. If you skip replacing the filter, you’ll contaminate your new oil with the dirty filter.
