2009 CTS4 2007 STS
Just got a 2000 sts 91k on the clock. The car seems to be leaking oil but i can't find the leak. not enough where i'll have to put some in before the changing the oil judging from the paperwork and talkn to the previous owner. There's no oil on the ground after the car is parkd but you can smell it after a short period of time, not enough to see and not a strong smell. looking up under the car its hard to tell but a plate that seems to cover the exhaust has a little oil on it. any idea where this could be coming from or has anyone had any experience?
