Just did another Mobil 1 oil change at 170,500 miles and noticed I've been rounding the original 10 year old drain plug, so it's time to retire it. Has anyone used and been satisfied with the Dorman "no mess oil drain" product which does not require removing the plug each oil change. Saw it on RockAuto for about $6. Or would you recommend another product....or just stay with a conventional plug. I'm remaining optimistic that she has many more oil change cycles to go
