I personally change the oil in my 06 Sonata LX. My last oil change I noticed a slow, small drip coming from the drain plug. The drain plug could not be tightended any further (trust me, it's not over tightened), so I thought it was the crushing washer. I just changed it again yesterday morning, and it still drips, even with a new washer. It's not cross threaded no metal shards. I get the washer from the dealer, is it possible it's too thick? Not the right material? Help! This is absolutely frustrating!
