Engine intervals

BMW N74 maintenance intervals

What BMW's own US maintenance booklets schedule for the M760i (N74B66TU), plus SixLine's labelled estimates for everything else — in miles and kilometres.

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 N74 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.

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.

Air-filter timing depends on the model column, so different cars on this engine can sit at different services in the same year.

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.

Estimates, not official BMW figures for your car. The BMW figures are read from BMW USA's printed maintenance booklets for US-market cars, in miles; the kilometre values are our conversion (one oil service is our derivation from the booklets: ≈ 10,000 mi ≈ 16,000 km). Everything in the estimates table is SixLine's own number, not BMW's. BMW's Condition Based Service (CBS) decides the real due date on your car, and your owner's manual or a BMW center is the authority for your VIN. The booklet figures are for US-market cars; other markets (EU, UK, Asia) may differ.
