Why check the motor oil level in my Mercury Cougar?

Engine oil lubricates moving parts in your engine. If your oil runs low, engine parts can grind together, generate too much heat, and cause your Cougar’s engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.

How hard is it to change Mercury Cougar oil at home?

First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Getting a professional oil change reduces the risk of something going wrong during the service, but it’ll also help your car perform smoothly down the road.

Why is my Mercury exhaust smoke gray or blue?

There could be an oil leak and your engine is burning oil. Looks like it’s time for a professional to take a look. The leak could be the result of worn valve seals, blown piston rings, or worn cylinder walls.

Where can I get Mercury Cougar oil changes?

You can count on Firestone Complete Auto Care for your Mercury Cougar 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 Mercury Cougar oil light comes on?

If you’re overdue for an oil change, it might trigger your Mercury Cougar 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 Mercury Cougar?

You should replace your Mercury Cougar during each oil change. The filter captures debris and contaminants to help keep your oil clean, which means the filter gets dirty. If you skip replacing the filter, you’ll contaminate your new oil with the dirty filter.

How Often to Change 1990 Mercury Cougar Oil

Looking for oil change recommendations for your 1990 Mercury Cougar? Look no further than Firestone Complete Auto Care! We're experts in more than tires. We know the ins and outs of motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

Mercury recommends having your 1990 Mercury Cougar’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of Mercury-recommended oil change intervals, your Cougar may need an oil change if your check engine light is on, you hear engine knocking, smell oil inside the vehicle, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than Mercury recommends if you haul heavy loads, drive in dusty areas, adventure off-road, or go long distances at low speeds. More frequent oil changes generally won't harm your Mercury Cougar. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

What Type of Oil Does My Mercury Cougar Need?

Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Mercury Cougar.

Motor oil helps lubricate the engine’s moving parts, regulate engine temperature, and prevent the build-up of harmful substances within the engine. During an oil change, an auto technician will change your Cougar’s oil, replace and recycle your used oil and filter, check all of your other filters, refill vital car fluids, and perform a free inspection on the rest of your vehicle. You can rest assured knowing that we seek to do what’s best for your Cougar by considering your driving preferences, and the number of miles on your odometer.
