It seems to be oil, but i am not entirely sure... i put some lubromoly something with the oil change this time so its dark gray. The oil seems to be the color of regular convrentional oil, perhaps even green, but i cant really tell... its on the drivers side and it comes down around the oil pan and drips into both of the bottom covers. Im thinking it might be the powersteering fluid, but i dont know for sure... you cant tell from underneath where its coming from and from over head, its not noticeable even with the airbox out. any help would be appreciated. thanks
