If you have recently had your car serviced you may be surprised to find some oil on your drive afterwards. If you are not sure if the oil was there before then put a piece of paper underneath the front of the car and run the engine for a little bit. Then turn it off and see if there is any oil on the paper. If there is, then you may well have a leak.

When the service is carried out, there is a chance that they could soil some oil on to the heat shield or plate that is fitted under most vehicles. Over the next day or so this lol could start to work it away out and that could be why you are seeing on the door. If there seems to be more oil each time or you notice that it is happening longer than a day or so then you need to investigate. First thing to check is the engine oil level using the dipstick. If this is low and it’s just been serviced it is most likely that you have a leak. The leak could becoming from an ill fitting oil filter or it could be that the sump plug has not been fitted correctly.
