How Often to Change 1985 BMW 635CSi Oil

Looking for oil change recommendations for your 1985 BMW 635CSi? Get the advice you need at Firestone Complete Auto Care! We're experts in more than tires. We know all about 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.”

Your 1985 635CSi’s oil should be changed according to BMW’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. Outside of BMW-recommended oil change intervals, your 635CSi may need an oil change if your check engine light is on, you hear engine knocking, smell oil inside the vehicle, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by BMW if you regularly haul heavy loads, drive in dusty areas, enjoy off-roading, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your BMW 635CSi. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

Oil Change Q&A for Your 1985 BMW 635CSi

  • What can low oil do to my BMW 635CSi engine? Motor oil lubricates important engine parts. If you're low or out of oil, engine parts can grind together, generate too much heat, and eventually lead to BMW 635CSi engine failure. That’s why you should check your oil and get it changed regularly.
  • How hard is it to change BMW 635CSi 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 with your vehicle down the road.
  • Why is my BMW 635CSi spewing blue or gray exhaust smoke? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. The leak could be the result of worn valve seals, damaged piston rings, or worn cylinder walls.
  • Where can I get BMW 635CSi oil changes? Firestone Complete Auto Care is here to care for your vehicle with our BMW 635CSi oil changes and more. Our expert technicians will also suggest the best oil for your vehicle, address oil leaks, and swap out your oil filter.
  • Why is my BMW 635CSi oil light illuminated? Your BMW 635CSi oil change reminder light might illuminate if it’s been too long since your last oil change. On the other hand, the oil pressure light might illuminate due to a clogged oil filter, a faulty oil pressure sensor, low engine oil levels, or a malfunctioning oil pump.
  • Does my 635CSi's oil filter need to be changed during my oil change? You should replace your BMW 635CSi during each oil change. The filter captures debris and contaminants to help keep your oil clean, which means the filter gets dirty. If you skip replacing the filter, you’ll contaminate your new oil with the dirty filter.
