1991 GMC Sonoma Oil Change Q&A

  • Why check the motor oil level in my GMC Sonoma? Motor oil lubricates important engine parts. If your oil reservoir is low or empty, these components can grind against each other, generate excess heat, and cause your GMC Sonoma engine to fail. 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. 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 it’ll also help your car perform smoothly down the road.
  • Why is my GMC exhaust smoke gray 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, blown piston rings, or old cylinder walls.
  • Who does GMC Sonoma oil changes? Firestone Complete Auto Care performs GMC Sonoma oil changes and more! Our technicians also replace oil filters, troubleshoot oil leaks, and advise on the right oil for your ride.
  • What can cause the oil light on my GMC Sonoma to illuminate? If you’re overdue for an oil change, it might trigger your GMC Sonoma 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.
  • Should the oil filter be replaced when getting an oil change for my GMC Sonoma? It’s highly advised you replace the oil filter in your GMC Sonoma every time you change the oil. After all, what’s the point of changing our oil if you’re just going to send fresh, clean engine oil through an already dirty filter?
