2021 Mercedes-Benz GLS450 Oil Change Q&A

  • What can low oil do to my Mercedes-Benz GLS450 engine? 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, generate too much heat, and cause your GLS450’s engine to fail. That’s why you should check your oil and get it changed regularly.
  • How hard is it to change Mercedes-Benz GLS450 oil at home? Changing your own oil isn't as convenient as you might think. 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 it’ll also help your car perform smoothly down the road.
  • Why is my Mercedes-Benz GLS450 spewing blue or gray exhaust smoke? 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, blown piston rings, or damaged cylinder walls.
  • Who can change the oil on my Mercedes-Benz GLS450? You can count on Firestone Complete Auto Care for your Mercedes-Benz GLS450 oil change, oil filter replacement, oil leak diagnostics, and more! Our expert technicians will even advise the right oil for your vehicle.
  • What does it mean if my Mercedes-Benz GLS450 oil light comes on? The oil change light in your Mercedes-Benz GLS450 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.
  • Do I need to change my GLS450's oil filter when I get an oil change? It's recommended that you replace your Mercedes-Benz GLS450 oil filter with every oil change. Otherwise, you send fresh, clean motor oil through a dirty filter. That's like putting on muddy socks after a shower.
