I found a (2 ft. diameter) puddle in my garage where I park my Saab (and my GLI when I'm driving the Saab). At first I though it was water because this part of the garage is low and rain water collects there sometimes. After days with no change in size (water usually evaporates quickly during the summer months) I realized that the puddle is some kind of oil after trying to mop it up. I have checked the engine oil, hydraulic fluid for the convertible top, brake fluid, and power steering fluid in the Saab, and I did not notice low fluid levels. The car has leaked since I got it three years ago, but never at this rate. The amount of fluid on the garage floor seems large enough that there would be a visible change in fluid level for power steering fluid or hydraulic fluid for the top, but not the engine oil, which leads me to believe either the engine leaks got way worse or the transmission is leaking (while standing still). Has anyone else had a similar experience. Any suggestions on how to pinpoint the source?
