Oil Changes for 1999 Mitsubishi Diamante

Not sure how or where to get your Mitsubishi Diamante’s oil changed? Look no further than Firestone Complete Auto Care! Our expertise goes beyond tires. We know all about 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.”

Your 1999 Diamante’s oil should be changed according to Mitsubishi’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. No matter the mileage, your Diamante may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Mitsubishi if you regularly haul heavy loads, frequent dusty roads, adventure off-road, or drive at low speeds for long distances. Generally, getting more frequent oil changes won’t hurt your Mitsubishi Diamante. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

Your local Firestone Complete Auto Care has the right 1999 Mitsubishi Diamante motor oil: either synthetic or conventional. Mitsubishi has specifically identified either synthetic or conventional as the best motor oil for your 1999 Diamante. This oil helps lubricate engine parts, regulate engine temperature, and prevent harmful substances from accumulating in the engine. During your oil change service, an auto technician will change your Diamante’s oil, replace and recycle your used oil and filter, check all of your other filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can drive with confidence knowing that we look out for you and your Diamante by taking into account your driving habits, climate,
