In my opinion that is pretty normal for an older engine with a questionable
maintenance history.  Even many new cars with good maintenance will turn the
oil black in short order.  You constantly have products of combustion
leaking by the rings and ending up in the oil which causes it to turn dark.
If you do have sludge build up in the engine I would just leave it be until
such time as you want to tear the engine apart and clean it out.  The sludge
is pretty happy sitting where it is and is unlikely to cause any real
problems.  Those "quick fix" products on the other hand are a wiped bearing
waiting to happen.  If you break the crud loose it has to go somewhere...
It can stop up the strainer on the oil pickup starving the engine for oil or
little bits can plug up critical passages that feed the bearings and
hydraulic lifters.
