I don't know if it's still posted, but at one time "they" used to say 
that each year do-it-yourself oil changes put more oil into the 
environment than the Exon Valdese oil spill.  Of course back in the old 
days we put the stuff out in the gravel road, and the county would spray 
the stuff on the roads along with brine.  Those gravel roads would get 
like concrete.

Oil will only produce a temporary protection. It might last for a few 
years, but it will eventually disappear.
Part of the problem is the moisture penetrates the concrete surface and 
makes it difficult to protect that area just below the top.
Tar on the leg and then a bag of the driveway patch which does seal with 
the concrete might work.  It'll add weight, but probably not much 
strength. OTOH at that point you don't really need much strength.
