Review on Dorman 65423 Engine Oil Drain Plug: Ideal Replacement for Buick, Cadillac, and Chevrolet Models by Wanick Palermo

It's nice that Revain are offering this as the price is much better than local dealers or parts shops. Original equipment metal is soft and can easily come loose when removed. Make sure you tighten it to the recommended GM value (printed on the oil pan) so it doesn't come loose next time. It uses a 10mm head, which is pretty small and can't handle a lot of twists. I also recommend a 6 point head instead of a 12 point head.
