Strange oil leak

[HalifaxMike]

Hi everyone, here is an weird one. I have oil (?) or an oil like substance dripping from just behind the left rear wheel. i've peered up into the wheel well but really can't see much indication of where it is coming from. I carry a spare gallon of oil in the compartment where the CD changer would go and my first thought was that had leaked but that isn't the case.

Any ideas?

Thanks,

Mike
