I always do my own oil changes as this way I get to look under the car and '' SEE FOR MYSELF" what needs attention ..02 civic has the filter above the drive shafts so after you drain the pan and you go after the filter there is always a little left and of course that comes out down your arm (lol) and across the drive shafts and on to the exhaust pipe.lol..(damn engineers) for Honda..I take all my oil and filters to the local recycling facility (free of charge) for proper disposal
