When to Change 1991 Porsche 911 Engine Oil

Looking for oil change recommendations for your 1991 Porsche 911? Get the advice you need at Firestone Complete Auto Care! Our expertise goes beyond tires. Oil and lube services are also our specialties. 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 911’s oil should be changed according to Porsche’s recommended oil change intervals. See mileage and month specifics in the above table. Outside of Porsche-recommended oil change intervals, your 911 may need an oil change if your check engine light is on, you hear engine knocking, 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 Porsche recommends if you haul heavy loads, drive in dusty terrain, adventure off-road, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage your Porsche 911. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

During your oil change service, a technician will change your 911's oil, replace and recycle the old oil and filter, inspect the rest of your car’s filters, top-off essential 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 911 by considering your driving style, weather and road conditions,

1991 Porsche 911 Oil Change Q&A

  • What can low oil do to my Porsche 911 engine? Engine oil lubricates moving parts in your engine. If you're low or out of oil, engine parts can grind together, generate excess heat, and eventually lead to Porsche 911 engine failure. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • How hard is it to change Porsche 911 oil at home? First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Having your oil changed professionally can not only reduce the risk of something going wrong during the service, but also help your car perform down the road.
  • Why is my Porsche 911 exhaust smoke grayish or blue? You could have an oil leak and have a case of burning oil. Looks like it’s time for a professional to take a look. The leak could be caused by several issues like leaking valve seals, fried piston rings, or damaged cylinder walls.
