How to Change Your BMW Oil at Home

An oil change is the single most important maintenance item on your BMW. Here's how to do it yourself and save €100-200 every time.

What You Need

Parts

• Engine oil (see our oil guide for your specific engine)
• Oil filter (Mann HU816x for most inline-6, HU6004z for 4-cylinder)
• Drain plug washer (aluminum crush washer)

Tools

• 17mm socket or wrench (drain plug)
• Oil filter cap wrench (76mm 14-flute for most models)
• Jack and jack stands (or ramps)
• Drain pan (at least 8 liters)
• Funnel
• Paper towels / rags

The Procedure

1. Warm Up the Engine

Drive for 5-10 minutes. Warm oil flows better and carries more contaminants out.

2. Lift the Car

Jack up the front and place on jack stands. Or drive onto ramps. Never work under a car supported only by a jack.

3. Remove the Drain Plug

• Place drain pan under the oil pan
• Remove the 17mm drain plug
• Let oil drain for 10-15 minutes
• Replace the crush washer on the drain plug
• Reinstall drain plug — torque to 25 Nm (don't overtighten!)

4. Replace the Oil Filter

• Locate the oil filter housing (top of engine on most BMWs)
• Remove the filter cap with the 76mm wrench
• Pull out the old filter element
• Replace the O-ring on the cap (included with new filter)
• Insert new filter element
• Reinstall cap — torque to 25 Nm

5. Fill with New Oil

• Remove the oil fill cap (top of valve cover)
• Pour in the correct amount (check your engine — typically 5.0-6.5L)
• Start with 0.5L less than spec, then check the level
• Start the engine, let it run for 30 seconds
• Turn off, wait 2 minutes, check dipstick or electronic level
• Top up to the correct level

6. Reset the Service Indicator

• Use BimmerCode, Carly, or the instrument cluster reset procedure
• Don't skip this — the CBS system needs to know the oil is fresh

Common Mistakes

• Overtightening the drain plug — strips the oil pan threads (aluminum pan!)
• Forgetting the crush washer — causes a slow leak
• Overfilling — excess oil foams and can damage seals. Check the level!
• Wrong oil — always use BMW LL-01 or LL-04 approved oil
• Not resetting the service indicator — CBS will keep nagging you

Time and Cost

• Time: 30-45 minutes
• Parts cost: €40-70 (oil + filter + washer)
• Dealer cost for same service: €150-300
• Savings: €100-230 every oil change

Do this 2-3 times per year and you'll save €300-700 annually. Plus you'll know it was done right.
