I am leaking some fluid but don't know what it is. I notice it after I move the car. It sits in the garage for 4 days, and I see a little spot and enough fluid to pick up with my finger.

I think it might be motor oil (but it's not black), I think it might be brake fluid. I have checked both and their levels seem fine so far.

How can I tell what it is?

Thanks again!!!

 

check the coolent

 

Oil shouldnt be black. Coolant should be green. ATF should be red. Id bet its oil. Try smelling it.
