BMW S68 maintenance intervals

BMW's maintenance booklets never name an engine: they list services by model column and count them in engine oil services ("every 6th engine oil service, approx. 60,000 mi"). This page reads those booklets for the cars that carry the S68 and prints their figures in the first two tables. Where BMW gives no number, a separate table shows SixLine's own estimates, labelled as such.

No BMW booklet figure for S68 spark plugs is shown here: the booklets print a different service by model column (3rd or 6th) and the sources we have do not settle which applies to which production run. SixLine's own estimate is in the estimates table below.

Intervals BMW prints for S68 cars

An oil service is the booklet's unit, but no booklet prints a mileage for the oil change itself (BMW calls it Condition Based Service). The distance shown for one oil service is therefore derived, our own division of what the booklets do print: from MY2017 the 2nd service is "approx. 20,000 mi", so one service ≈ 10,000 mi ≈ 16,000 km. The oil change itself is not fixed: CBS counts it down on the car, and BMW also codes some cars with a shorter or longer oil interval (option codes 8K…). BMW of North America's bulletin SI B01 06 13 (October 2013) states the engine-oil "Due in" date uses a 12-month interval on BMW vehicles produced on or after July 1, 2013 (24 months before that; E71 and E88 excepted), and the vehicle check a 48-month interval.

How the intervals change by model year

"—" means the booklet gives no single figure for these cars that year (a blank cell, or a value printed at two different services), or, in the oil-service column, that no booklet of that year lets us derive one; it does not mean the service does not exist. Air-filter timing depends on the model column, so different cars on this engine can sit at different services in the same year.

Running-in service and differential oil on M cars

The booklets prescribe a 1,200-mile (≈ 1,930 km) running-in service for M models only: engine oil and filter and rear-axle differential oil (older booklets add manual-gearbox oil), and then the running-in check is switched off. After that, the rear differential fluid is on the 5th oil service.

SixLine's estimates for everything else

BMW leaves these items to CBS or gives no number: brake pads and brake discs run through CBS, brake fluid is a CBS item with no figure, and the cooling system is described as long-term rated. So SixLine starts from the preventive estimates below. They are SixLine's own numbers, not BMW's, and every interval can be edited in the app. For a US car covered by a booklet, the BMW figures in the table above replace the estimate for those items.
