Someone posted awhile back that he bought oil at WalMart for his car (don't remember the brand of oil) and when he went to use it, discovered it was some jerk's used oil poured back nice & neat into the bottles and obviously returned for refund. Talk about recycling - and "free" oil, no less! It's unbelievable the depths of depravity some people will stoop to just get an edge in everyday dealings. I hope there's an eighth circle of retribution such people will experience in Dante's Inferno in which they'll be lowered by their short hairs into boiling, sludgy oil for eternity plus a day.
