Engine oil: quantity and approval

Oil change: 6.5 l (BMW specification tables valid from 07/2017; BMW UK technical data from production week 44/2017). BMW’s Coupé handbook (VI/18) approves BMW Longlife-04 and Longlife-12 FE, SAE 0W-20, 5W-20, 0W-30, 5W-30, 0W-40 or 5W-40; failing that, up to 1 litre of ACEA C2 or C3. No additives. The level is measured electronically; BMW asks for a detailed measurement after every refuelling.

What the service display covers

The car calculates each due date (Condition Based Service): the distance or time left appears briefly when the ignition is switched on, details are in the vehicle status menu, and the data is also stored in the key. BMW Service Inclusive lists the items it triggers: oil service with filter, vehicle check, air filter, microfilter, spark plugs and brake fluid. Brake fluid is time-based; periods with the battery disconnected are not counted, so have the workshop update it. BMW’s handbook gives no mileage for any item.

Timing drive

Chain (ADAC: “Steuerkette”). BMW’s B58 training document places the chain drive on the transmission side, in two parts (lower and upper chain), where the gearbox’s inertia reduces the loads. No scheduled replacement in the documents consulted.

Prepare the next service

Before the appointment, note 6.5 l of oil and an approved grade (Longlife-04 or Longlife-12 FE). Hand the advisor the key last used: BMW stores the service data in it. Note the build month (registration document or VIN plate): ADAC lists a BMW recall of February 2026 for cars built 05/2020–10/2024 (deposits in the starter relay, fire risk; starter replaced). Have BMW check your VIN. Ask for a printout of the due items: BMW gives no mileage for them.

Oil level

Detailed measurement after every refuelling

BMW asks for a detailed measurement after every refuelling: standing, car level, engine warm and idling. Monitoring while driving gives a value after about 30 minutes. Add oil only when a message asks, in the quantity shown; do not overfill.

Other maintenance items — petrol

As the car’s service requirement dictates

BMW lists as regular, CBS-triggered services: oil service with filter, vehicle check to BMW specifications, air filter, microfilter, spark plugs and brake fluid. No mileage is given for any of them.

Brake fluid

Calendar-based (CBS)

Counted in time, not kilometres. Periods with the battery disconnected are not counted: have the workshop update the time-based items (brake fluid, and where applicable oil and microfilter). The handbook does not state the period.

Source [7]

Coolant

Regular check, engine cold

Engine cold, level between Min and Max: marks on the side of the tank or yellow marks in the filler neck depending on the engine (loosen the cap first to release pressure). Close until it clicks with the arrows aligned, and have any loss traced. Additives: ask the workshop.
