Since 2 days I can see small circles (3-4 cm radius) of fuel stains in the car park and this happens right after I park the car. After few hours there is no leak. Can someone tell me what could be the reason behind this. More info below as I feel it's necessary to include that. My car's ODO stands at 10,500 KM and if I dip the stick and test the oil level is very low. It's around 1-15 MM on the dispstick. I did not change oil in the 1st service. As said in this thread http://www.teamfiat.co.in/engine-compartment/4230-engine-oil-level.html a visit to the SC is due.
