I have EK wagon model 2012, few days ago when i started the car in the morning. engine oil started spilling out of the engine very quickly somewhere from underside, however after few seconds it stopped. when i checked the oil level it had already reduced to half. i topped it up and then drived it the whole day without any problem. However i went to the mechanic in the evening and he suggested oil filter change. i changed the oil filter and oil as well although it was not due. Few days later the same thing happened, when i started the car in the morning, the oil spilled out and this time within few seconds all the oil was gone. Any suggestions about the possible cause?
