Had the car seviced and the person changing the oil reported a leak around the oil pan. Called a certified mechanic and he stated that it would cost about $390, i live on a strict budget and opted out of getting the leak repaired, i do monitor the oil daily to make sure that the leak is not getting any worse.
It was one of several things that became an issue after front motor mount failed and I had recurring leaks etc.
