Step-by-Step Guide to Changing Oil on Your BMW

By Rae CastellanoEngines & Vehicles Writer

Why Regular Oil Changes Matter for Your BMW

Oil keeps your BMW's engine running smoothly. Over time, oil breaks down and gets dirty. Changing it regularly helps your engine last longer and run better. Most BMW owners change their oil every 10,000 to 15,000 miles, though you should check your owner's manual for your specific model.

Clean oil reduces friction inside your engine and helps remove dirt and debris. When oil gets old, it loses these protective qualities and can lead to engine wear. Regular oil changes are one of the most important things you can do to keep your BMW in good condition. Think of it as giving your engine a fresh start every few thousand miles.

What You'll Need Before You Start

Gather these items before you begin:

  • New oil (the correct type and amount for your BMW model)
  • A new oil filter
  • An oil drain pan
  • A wrench or socket set
  • An oil filter wrench
  • Jack and jack stands (if you need to lift your car)
  • Rags or paper towels
  • Safety glasses
  • A funnel
  • A flashlight or work light

Check your BMW's manual to find out which oil type your car needs. Using the wrong oil can harm your engine. Different BMW models require different oil viscosity ratings. You'll also want to know the oil capacity—how much oil your specific model holds—so you add the correct amount.

Having everything ready before you start makes the job go faster and smoother. You won't need to stop halfway through to hunt for a tool or part. Most of these items are inexpensive and worth keeping on hand for future maintenance.

Safety First

Let your engine cool for at least five minutes before starting. Hot oil can burn you. Park on a flat, level surface and engage the parking brake. If you're lifting your car, use a jack and jack stands—never rely on a jack alone. Jack stands provide a backup safety measure in case something goes wrong.

Wear safety glasses to protect your eyes from oil splashes. Consider wearing gloves to keep oil off your hands, though many people prefer bare hands for better grip. Work in a well-lit area so you can see what you're doing. If you're working in a garage, make sure the space is ventilated. Never work under a car that's only supported by a jack—always use jack stands as well.

Drain the Old Oil

Once your engine is cool:

  1. Locate the oil drain plug underneath your BMW. It's usually a bolt on the bottom of the engine.
  2. Position your drain pan below it.
  3. Use your wrench to loosen the drain plug by turning it counterclockwise.
  4. Once it's loose enough, unscrew it by hand (be careful—residual heat may remain).
  5. Let all the old oil drain into the pan. This may take several minutes.
  6. Wipe the drain plug clean with a rag.
  7. Screw the drain plug back in by hand, then tighten it with your wrench. Don't overtighten it.

The old oil will be darker and dirtier than new oil. This is normal. Let it drain completely—don't rush this step. Some oil will cling to the inside of the pan and engine, but most of it will drain out if you give it time. If the drain plug is stuck, apply penetrating oil and wait a few minutes before trying again. Be patient; forcing it could strip the threads.

Replace the Oil Filter

Your BMW's oil filter location depends on your model. Check your manual to find it.

  1. Position your drain pan underneath the filter.
  2. Use an oil filter wrench to turn the filter counterclockwise until it comes loose.
  3. Unscrew it by hand and let any remaining oil drain into the pan.
  4. Wipe the filter mounting surface clean with a rag.
  5. Take your new filter and apply a thin layer of new oil to the rubber gasket (the ring on top).
  6. Screw the new filter on by hand until the gasket touches the mounting surface, then turn it another three-quarter turn. Don't use a wrench for this step.

The oil filter removes dirt and particles from your oil. Over time, it becomes clogged and needs replacement. The gasket on the new filter creates a seal. Applying a thin layer of oil to it helps ensure a tight seal and makes removal easier next time. Hand-tightening is sufficient—over-tightening can damage the filter or make it hard to remove later.

Add New Oil

Now it's time to add fresh oil:

  1. Locate the oil filler cap on top of your engine. It usually has an oil can symbol on it.
  2. Unscrew and remove the cap.
  3. Place a funnel in the opening.
  4. Pour in the amount of new oil your manual recommends. Start with slightly less than the full amount.
  5. Replace the oil filler cap.
  6. Start your engine and let it run for about 30 seconds, then turn it off.
  7. Wait a minute for the oil to settle.
  8. Check the oil level using your dipstick or electronic gauge (your manual will explain how). Add more oil if needed until it reaches the proper level.

Adding oil gradually helps you avoid overfilling. Too much oil can damage your engine just as much as too little. When you start the engine, the new oil circulates through the engine and the new filter. This is why you need to check the level again after running it. The level may be slightly lower than expected because some oil is now in the filter.

Final Steps

Make sure the drain plug and oil filter are tight. Lower your car if you lifted it. Dispose of your old oil at a recycling center or auto parts store—never pour it down the drain. Many auto parts retailers will take used oil for free or for a small fee.

Keep a record of when you changed your oil and how many miles were on your BMW. This information is useful for future maintenance and helps you remember when the next change is due. Some people keep records in a notebook, while others use their phone or computer. Having this history can also be helpful if you ever sell your car, as it shows you've maintained it properly.

When to Seek Professional Help

If you're uncomfortable working under your car, or if you run into unexpected problems, a BMW service center can handle an oil change for you. There's no shame in getting professional help if you need it. Professional technicians have the right equipment and experience to do the job quickly and correctly.

You might also consider professional service if your drain plug is stuck, if you can't locate the oil filter, or if you're unsure about any step. A BMW dealer or certified mechanic can also check other parts of your car while they're working on the oil change, which may catch problems early.

Key Takeaways

  • Regular oil changes keep your BMW's engine healthy and running smoothly.
  • Always let your engine cool and work on a flat, level surface with proper safety equipment.
  • Drain old oil completely, replace the filter, and add the correct type and amount of new oil.
  • Check your owner's manual for your specific model's oil type, capacity, and drain plug location.
  • Keep records of your oil changes to track your BMW's maintenance history.
  • If you're uncomfortable with any part of the process, professional service is a good option.

Frequently Asked Questions

How often should I change the oil in my BMW?

Most BMW models recommend an oil change every 10,000 to 15,000 miles. However, this can vary depending on your specific model year and driving conditions. Always check your owner's manual for the recommended interval. Some newer BMWs have longer intervals than older models. If you do a lot of short trips or drive in dusty conditions, you might need to change your oil more often.

What type of oil does my BMW need?

Different BMW models require different oil types. Your owner's manual will specify the exact viscosity and grade your car needs. Common BMW oil types include 5W-30 and 0W-40, but this varies by model and year. Using the wrong oil can affect engine performance and longevity. If you're unsure, ask a BMW dealer or check your manual before purchasing oil.

Can I change my BMW's oil if I've never done it before?

Yes, many people change their own oil for the first time. Take your time, follow each step carefully, and refer to your manual whenever you're unsure. Watch instructional videos specific to your BMW model if that helps. If at any point you feel uncomfortable or run into a problem you don't understand, stop and seek professional help. There's no penalty for learning as you go, and getting it right is more important than doing it fast.

What should I do with my old oil after draining it?

Never pour old oil down the drain or into the ground—it's harmful to the environment. Instead, take it to a recycling center, an auto parts store, or a service station. Many places accept used oil for free. Some may even pay you a small amount for it. Store the old oil in a sealed container until you can take it to a recycling location.
