Hey Guys,

I went out to my G (2003 auto coupe) today and found a puddle underneath the driver side of the gas tank (under the plastic cover in front of the rear wheel).

It was dark brown (probably darker than it normally would be since it was all dirty).

I jacked it up and took the plastic cover off, turns out the bottom of the gas tank (driver side) is coated with what looks like oil (dark brown). I went to wipe it off with a paper towel, and the coating wiped right off, leaving only the bare shiny metal of the gas tank.

This made me think it was gas mixed with grime from under the car, but it doesn't smell like gas, and i tried to light the paper towel on fire after, and it barely lit up, if it was gas i think it would have burst into flames after I touched the lighter to it.

Oil wouldn't cause the coating to just wipe off the tank, so I started thinking it was brake fluid. Does the brake line from the driver side rear wheel run on top of the gas tank? That's the only thing that I can think of.
