Attention! It is not permitted to introduce additional additives of any kind into fuels and oils intended for cars by the company "BMW".
The vehicle manufacturer has set its own standards for oil use, therefore, for reliable engine operation, it is necessary to use oils of ACEA specification quality, with approval according to the CCMS specification, their compliance is given in the "Operation" section of this Manual.
The engine uses an oil level and pressure control system that monitors the oil pressure depending on the engine crankshaft speed and its level. The oil pressure in idle mode with a warm engine should be at least 0.5 kgf/cm². If the crankshaft speed is higher than or equal to idle speed, and the pressure is below 0.5 kgf/cm², the oil pressure warning signal flashes on the instrument panel. At maximum engine speed, the oil pressure should be within - 4.2+0,5 kgf/cm².
The oil pressure sensor is always installed with a new gasket and tightened to a torque of 20 N·m (2.0 kgf·m). The main reasons for the indicator to blink may be:
- low oil level;
- pressure sensor failure;
- oil pump drive failure;
- oil pump failure;
- increased wear of crankshaft bearings.
Engine lubrication system capacity (including 0.5 l in the oil filter) – 7.8 l.
