Not sure if it'll work, but if the topic numbers are still valid and transfered over then take the t= number in the old oildrop URL and put it on the end Number= of the new BITOG URL.
Your example, topic #000925, would then be -
http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=000925
So hopefully it'll be what your looking for or some other equally interesting random article from the past. YMMV
