Review on Dorman 65215 Engine Oil Drain Plug: Perfect Fit for Select Models by Brian Kingsford

The drain plug fits the Kia van without any problems, except maybe 16 mm instead of 17 mm. The dealer usually changed my oil except for COID cases where I couldn't get it or make an appointment. I found they rounded the corners of the drain plug and pushed the washer into the threads. I'm glad they didn't remove my oil pan. Had to use an Allen key to pull the plug out. This is the last free oil change I received from the dealer.
