BMW B58 petrol engine (3.0 l, six-cylinder)

This applies to every car fitted with the B58 engine.

What the B58 is

Inline six-cylinder petrol engine of 2,998 cc (82 mm bore, 94.6 mm stroke, 11:1 compression) with twin-scroll turbocharger, direct injection, double VANOS, a closed-deck crankcase and indirect charge-air cooling integrated into the intake. BMW places it in the same modular family as the B38, B48 and B57, and launched it in mid-July 2015 in the F30 340i (240 kW/326 PS and 450 Nm according to ADAC, which codes it B58B30A). BMW designates the version in the facelifted 2 Series M240i (2017) as B58B30M0. In 2021 the G42 M240i xDrive Coupé quotes 275 kW (374 hp) and 500 Nm from the same displacement.

Engine oil

BMW handbooks only list oils for topping up and leave the oil change to a qualified workshop; the list depends on the handbook edition. 5 Series G30 handbook (VI/20): BMW Longlife-04, -12 FE or -17 FE+, in SAE 0W-20, 5W-20, 0W-30, 5W-30, 0W-40 or 5W-40; otherwise up to 1 litre of ACEA C2 or C3. 2 Series Coupé G42 handbook (VI/22): BMW Longlife-12 FE or -17 FE+, in SAE 0W-20 or 0W-30 only; otherwise up to 1 litre of ACEA C2 or C5. No additives. Quantities published by BMW: 6.5 l for the B58B30M0 of the M240i (2017, “filling quantity”) and 7.2 l for an oil change on the G42 M240i xDrive Coupé (2021). No quantity is sourced here for other installations.

Timing drive

Chain, on the transmission side, confirmed by ADAC. According to BMW’s training document it is two-part: a lower chain drives an intermediate shaft, which passes the drive to the upper camshaft chain; the oil pump has its own chain and the tensioners are hydraulic with spring preload. The inertia of the transmission reduces the torsional vibrations acting on the chain. The sources consulted give no replacement interval.
