How Often to Change 1990 GMC K1500 Oil

Looking for oil change recommendations for your 1990 GMC K1500? Look no further than Firestone Complete Auto Care! We are experts in car care — not just tires. We know all about motor oil, too. 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.”

GMC recommends changing your 1990 K1500’s oil at regular intervals. Check out mileage and month info for your K1500 in the above table. Outside of GMC-recommended oil change intervals, your K1500 may need an oil change if your check engine light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, 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, adventure off-road, or drive at low speeds for long distances. More frequent oil changes generally won't harm your GMC K1500. 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.

What’s the Right Type of Oil for 1990 GMC K1500?

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1990 GMC K1500 motor oil at Firestone Complete Auto Care. GMC has most likely outlined either synthetic or conventional as the ideal engine oil for your 1990 K1500. Motor oil helps lubricate the engine’s moving parts, regulate engine temperature, and prevent the build-up of harmful substances within the engine. During an oil change, a technician will change your K1500's oil, replace and recycle the old oil and filter, inspect the rest of your car’s filters, top-off important fluids, and perform a courtesy inspection on your entire vehicle. You can drive easy knowing that we strive to do what's best for your vehicle and take into account your driving habits, and the number of miles on your odometer.

1990 GMC K1500 Oil Change Q&A

  • What can low oil do to my GMC K1500 engine? Engine oil lubricates moving parts in your engine. If you're low or out of oil, these components can grind against each other, generate too much heat, and eventually lead to GMC K1500 engine failure. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • 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 with your vehicle down the road.
  • Why is my GMC exhaust smoke gray or blue? There could be an oil leak and your engine is burning oil. 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, damaged piston rings, or worn cylinder walls.
