Looking for oil change recommendations for your 1994 Mercury Grand Marquis? Turn to Firestone Complete Auto Care! We are experts in car care — not just 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 changing your 1994 Grand Marquis’s oil at regular intervals. Check out mileage and month info for your Grand Marquis in the above table. Outside of Mercury-recommended oil change intervals, your Grand Marquis may need an oil change if your check engine light is on, you hear knocking sounds 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 terrain, go off-roading a lot, or drive at low speeds for long distances. Generally, getting more frequent oil changes won’t hurt your Mercury Grand Marquis. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.
Your local Firestone Complete Auto Care has the right 1994 Mercury Grand Marquis motor oil: either synthetic or conventional. Mercury has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1994 Grand Marquis. Motor oil reduces friction between engine components, maintain proper engine temperature, and prevent the build-up of harmful substances within the engine. During an oil change, an auto 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 rest assured knowing that we seek to do what’s best for your Grand Marquis by considering your driving preferences, and the number of miles on your odometer.
