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 1991 525i’s oil should be changed according to BMW’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. Your 525i may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, smell oil inside the vehicle, or notice excess vehicle exhaust. You may also need an oil change more frequently than BMW 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 BMW 525i. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your BMW 525i.

Motor oil helps lubricate the engine’s moving parts, keep the engine cool, and prevent harmful substances from accumulating in the engine. During your oil change service, one of our techs will change your 525i’s oil, replace and recycle your used oil and filter, inspect the rest of your car’s filters, top-off important 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 525i by considering your driving preferences, climate,
