Parts for your 2020 Bmw X3-Oil filter

2020 BMW X3 oil filter — what it does and how to look after it

Yes, an oil filter is fitted to the 2020 BMW X3 and it’s absolutely relevant. BMW’s Owner’s Handbook for the G01 X3, the BMW Technical Information System (TIS) and the BMW Electronic Parts Catalogue (ETK) all specify a replaceable cartridge-style oil filter in a top-mounted housing across the 2020 X3 engine range (petrol and diesel). It’s a normal, scheduled-service item.

The oil filter’s job is simple but critical: it traps fine metal, soot and sludge so clean oil can keep the turbo, timing chain and bearings happy. Modern BMW engines run tight tolerances and extended service intervals, so a quality filter matters for long-term reliability and smooth performance.

On the 2020 X3, the filter element sits in a top-mounted canister that’s easy to access. During a service the old cartridge and O-rings are replaced, the cap is refitted to the specified torque (commonly around 25 Nm—check the cap or TIS), and the engine is refilled with BMW-approved Longlife oil. The car’s Condition Based Service (CBS) should then be reset.

Recommended practice for Aussie and Kiwi conditions is to replace the oil and filter at the CBS prompt or about every 10,000–15,000 km or 12 months, whichever comes first. Short trips, dusty roads, towing or lots of idling all justify shorter intervals. Using the correct BMW Longlife oil grade from the handbook (petrol and diesel specs differ) helps the filter do its best work and keeps warranties and emissions systems onside.

• Always replace both O-rings on the filter cap and lightly oil them before install.
• Ensure the new cartridge clicks/seats fully into the cap or housing—wrong seating can bypass filtration.
• Use a new sump plug washer when draining the oil and check for leaks with the engine running.
• Avoid over-tightening the plastic cap—cracking the housing is an expensive mistake.

Signs the filter and oil are due include noisy cold starts, rough idle, or a CBS reminder. Sticking to fresh oil and a quality filter (genuine or OEM-equivalent) is cheap insurance for the X3’s turbo and variable valve gear, and keeps fuel economy and performance on point.

Popular questions about 2020 BMW X3 oil filters

How often should the oil filter be changed on a 2020 BMW X3?
BMW’s Condition Based Service will call it, but a good rule in Australia and New Zealand is every 10,000–15,000 km or 12 months. If the car does lots of short trips, dusty driving or towing, bring that forward to protect the turbo and timing gear.

What oil spec should be used with the 2020 X3 oil filter?
Use a BMW-approved Longlife oil as listed in the handbook for your exact engine. Petrol and diesel variants have different approvals and grades. Sticking to the correct spec ensures proper filtration, cold-start protection and compatibility with emissions systems.

Where is the oil filter located on the 2020 X3?
It’s a cartridge element in a top-mounted housing on the engine, making changes straightforward. Replace the cartridge and both O-rings, torque the cap to spec, then reset the CBS once the engine has been refilled and checked for leaks.
