Not sure how or where to get your Audi 90’s oil changed? Get the advice you need at Firestone Complete Auto Care! We are experts in car care — not just tires. Oil and lube services are also our specialties. 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.”
Audi recommends having your 1991 Audi 90’s motor oil changed at regular intervals. Check out mileage and month info for your 90 in the above table. Your 90 may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than Audi recommends if you haul heavy loads, frequent dusty roads, adventure off-road, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your Audi 90. 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.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Audi 90. Audi has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1991 90. Motor oil helps lubricate the engine’s moving parts, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. During your oil change service, a technician will change your 90's oil, replace and recycle your used oil and filter, inspect all of your other filters, top-off important 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 90 by considering your driving style, and mileage.
