There should be a bolt underneath the oil sump. Look where you put the oil in and try to follow it down and there will be what looks like a bathtub shape under the engine. Thats where the bolt should be and when you undo it all the oil will come out! Its very messy though! hope that helps, all cars are different but thats my experience of it

Need help, just sold our car on ebay and its meant to be getting picked up today!! dp decided to fill the engine oil first as it was really low but hes way overfilled it by mistake and now the car is pouring blue smoke! tried to drain the oil with a hose but its not working theres too much and dont know where the plug thing is under the car, anyone know
