Oil Drain Plug....RTV!

Just a note: Around here, just about any shop / 'Jiffy Lube' etc. will put a shot of RTV on the threads before they send it out. Talking to a friend that works at one of these joints, Too many shops have had to buy new engines for customers because the plug was forgotten / loose. They figure the bright colored RTV (Most use Orange or Yellow) let everyone know it was done.
I would pull the plug and check if it is stripped or not before crucifying anyone.
My two cents.:soapbox:
