When to Change 1985 GMC K2500 Engine Oil

Need more info about 1985 GMC K2500 oil changes? Look no further than Firestone Complete Auto Care! We're experts in more than 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 1985 K2500’s oil at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of GMC-recommended oil change intervals, your K2500 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 may also need an oil change more frequently than GMC recommends if you haul heavy loads, drive in dusty areas, go off-roading a lot, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your GMC K2500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

1985 GMC K2500 Oil Change Questions

  • Why check the motor oil level in my GMC K2500? Engine oil is a lubricant for the moving parts in your engine. If you're low or out of oil, these parts can grind together, overheat, and cause your K2500’s engine to fail. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my GMC oil on my own? First off, changing your own oil isn’t as easy as you’d think. You’ll have to figure out how to properly dispose of the oil and buy special tools. 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 K2500 spewing blue or gray exhaust smoke? Your engine could be burning oil due to a leak. Time to have a qualified technician check things out. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or old cylinder walls.
