BMW Maintenance Schedule: 3 Series, 5 Series, X5 & M Cars

Every BMW covered here uses the same basic system in the US: Condition Based Service (CBS). The car's display calls the oil change, at most every 10,000 miles (≈16,000 km) or 12 months, and calls the brake fluid by date, every 24 months. Most other items are counted in oil services rather than miles: the cabin microfilter every 2nd oil service (about 20,000 miles, ≈32,000 km) and the spark plugs every 6th on the non-M models covered here (about 60,000 miles, ≈97,000 km). What changes between models is the engine air filter, the M cars' tighter plug and differential schedule, and a few xDrive transfer cases.

This page lists what BMW's US maintenance booklets say across the range, then gives each model its generation, the model years our figures come from and the headline intervals, with a link to the full guide.

How BMW's Condition Based Service works

CBS is BMW's service reminder. It tracks three things on the display: the engine oil (by date and mileage), the brake fluid (by date) and the front and rear brake pads (by remaining wear). BMW's service information sets the CBS oil interval at 10,000 miles or 12 months, whichever comes first, for cars produced from July 2013 onward. The display may call for oil sooner after short trips, cold starts, idling or high engine speeds.

Everything else is keyed to the oil service count and done together with an oil service. The booklets phrase it as "every 2nd engine oil service (approx. 20,000 mi)" or "every 6th engine oil service (approx. 60,000 mi)". Keeping a record of each oil service is the only reliable way to know when those items are due.

What's the same across the BMW range

Item	BMW's US schedule
Engine oil and filter	When CBS calls for it; at most 10,000 miles (≈16,000 km) or 12 months
Cabin microfilter	Every 2nd oil service, about 20,000 miles (≈32,000 km)
Brake fluid	Every 24 months, when CBS shows it due
Brake pads and discs	Monitored by CBS; replaced when displayed
Engine coolant	Long-term rated; no scheduled replacement
Automatic and manual transmissions	Long-term rated; no scheduled replacement
All-wheel-drive transfer case	Long-term rated, except where the vehicle or the booklet says otherwise
Tire rotation	No interval in any booklet checked

BMW's long-term list says fluid replacement "is only necessary when repairs are being performed". If a shop quotes a coolant or transmission flush as "factory scheduled" on one of these cars, ask which BMW document it comes from.

BMW M3 and M4 (2015–2026)

The F80 M3 and F82 M4 (S55 engine) and the G80 M3 and G82 M4 (S58 engine). The M cars run a tighter schedule.

• A 1,200-mile (≈1,900 km) running-in service changes the engine oil and rear differential oil.

• Rear differential oil every 5th oil service, about 50,000 miles (≈80,000 km); Competition xDrive cars add the transfer case at the same count.

Other BMW models

We also reviewed BMW's booklets for two models that don't have their own guide yet:

• 4 Series (2023–2026): the same oil, cabin filter, spark plug and brake fluid intervals as the 3 Series. The MY2026 booklet puts the air filter at every 4th oil service, about 40,000 miles (≈64,000 km).
• i5 (2024–2026): as an electric car it has no oil service. BMW's electric-vehicle CBS uses a 24-month vehicle check with no mileage input, and brake fluid every 24 months.

For other BMW models, including cars built before the model years listed on this page, we haven't reviewed the schedule, so this page gives no figures for them. Use your owner's literature.
