Calling E60 owners....especially 2006 model without dip-stick. On Saturday I experienced a sudden loss in engine oil. Warning light came on saying engine oil is low, please add 1 litre.
There's no leakage whatsoever. Does it get evaporated or eaten up? Has anyone experienced such a problem? Please share.
AB salesman said it is normal bcoz the the oil viscosity is too thin. Still I don't find any reason for the oil to disappear.
