Noticed some oil stains on my driveway, took car to the lube shop to put on the lift guy said the leak is coming from the oil pan gasket.This should be covered under warranty i hope.
Next time...do the change yourself...it's the only way to ensure it's done right...oil changes are usually given to the most inexperienced tech (especially at places like Jiffy Lube, etc.)...trust no one with your oil/filter change and the Stang is really easy (only change for the 2010 is removing a plastic shield in order to access the oil filter).
