Itís not water.
so you pulled the interior above that grommet the leak comes from and looked inside?

capture some of the fluid and examine it.
see if it's miscible with water.

photos on the internet are not how you figure things out.

No not yet, although I will. I know it isnít water because water dries up, water doesnít leave a stain on your drive for months and months.

The liquid seems oily in consistency but doesnít smell of much.

No photos on the internet arenít always the solution but posting on a forum in the hope that some owners may have encountered this issue before isnít unreasonable. Thatís all Iím doing here.

If I canít figure it out I will ask my mechanic to look next time itís in.

I think it's gotta be diesel. Brake fluid would have dissolved and it doesn't look like the right place to be from the shock. Cracked fuel filler neck maybe?
