Looking for oil change recommendations for your 1990 Mercury Grand Marquis? 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. 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.”
Mercury recommends having your 1990 Mercury Grand Marquis’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 Grand Marquis may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the car, or notice excess vehicle exhaust. You may also need an oil change more frequently than Mercury recommends if you haul heavy loads, drive in dusty areas, enjoy off-roading, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your Mercury Grand Marquis. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1990 Mercury Grand Marquis motor oil at Firestone Complete Auto Care. Mercury has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1990 Grand Marquis. Motor oil reduces friction between engine components, keep the engine cool, and prevent the build-up of harmful substances within the engine. During your oil change service, a technician will change your Grand Marquis's oil, replace and recycle your used oil and oil filter, inspect the rest of your car’s filters, refill vital car fluids, and perform a courtesy inspection on your entire vehicle. You can drive with confidence knowing that we look out for you and your Grand Marquis by taking into account your driving preferences, weather and road conditions,
