When to Change 1985 GMC G2500 Engine Oil

Looking for oil change recommendations for your 1985 GMC G2500? Look no further than Firestone Complete Auto Care! We're experts in more than tires. Oil and lube services are also our specialties. 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.”

Your 1985 G2500’s oil should be changed according to GMC’s recommended oil change intervals. Check out mileage and month info for your G2500 in the above table. No matter the mileage, your G2500 may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, drive in dusty areas, enjoy off-roading, or go at low speeds on long distance trips. Generally, getting more frequent oil changes won’t hurt your GMC G2500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

What Kind of Oil Should I Get for My GMC G2500?

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1985 GMC G2500 motor oil at Firestone Complete Auto Care.

Motor oil helps lubricate the engine’s moving parts, keep the engine cool, and prevent the build-up of harmful substances within the engine. During an oil change, one of our techs will change your G2500’s oil, replace and recycle the old oil and filter, check all of your other filters, top-off important fluids, and perform a free inspection on the rest of your 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.

1985 GMC G2500 Oil Change Q&A

  • What can low oil do to my GMC G2500 engine? Motor oil lubricates important engine parts. If you're low or out of oil, these parts can grind together, overheat, and cause your G2500’s engine to fail. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • How hard is it to change GMC G2500 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 G2500 spewing blue or gray exhaust smoke? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. The leak could be caused by several issues like leaking valve seals, blown piston rings, or old cylinder walls.
