Oil Change Q&A for Your 2003 Mercury Grand Marquis

  • Why check the motor oil level in my Mercury Grand Marquis? Motor oil lubricates important engine parts. If your oil runs low, these components can grind against each other, overheat, and eventually lead to Mercury Grand Marquis engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • How hard is it to change Mercury Grand Marquis oil at home? Changing your own oil isn't as convenient as you might think. 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 help your car perform down the road.
  • Why is my Mercury Grand Marquis 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 worn cylinder walls.
  • Who offers Mercury Grand Marquis oil changes? You can count on Firestone Complete Auto Care for your Mercury Grand Marquis oil change, oil filter replacement, oil leak diagnostics, and more! Our expert technicians will even advise the right oil for your vehicle.
  • Why is the oil light on in my Mercury Grand Marquis? Your Mercury Grand Marquis oil change reminder light may come on if you're overdue for an oil change. The oil pressure light will typically come on if the oil level in the engine is too low, the oil pump is failing, you have a clogged oil filter, or there's a faulty oil pressure sensor.
  • Does my Grand Marquis's oil filter need to be changed during my oil change? It’s highly advised you replace the oil filter in your Mercury Grand Marquis 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?
