and that the level is decreasing while the engine is running,
If the engine oil level does not drop after the engine
has been started, switch off the engine immediately

drop to the “a” level reference mark, check that there are
no leaks in the lubrication circuit and that the oil passages
and engine oil pump are not damaged.
