I can't believe that... I usually check the dip stick after I am finished to make sure I eye-balled the amount of oil correctly, but I can't say I have ever checked the stick after an iol change just to make sure I put the oil in the right place...

If my gf can change her own oil,(albeit she used to stab a screwdriver through the filter to unscrew it cause it was too tight for her little hands) but still, if she can do it, I don't see any excuse for anyone...
