This might be elementary, but need some help. I was trying to drain oil from my 89 300 SE. I tried in vain to open the drain plug for 2 hours. I am well aware of the righty-tighty/lefty-loosey and still did not work. I talked to a MB dealership tech and he said if it's stuck, have at it with a vice grip and change the drain plug. I have screwed the head of the old drain plug and no oil draining yet. Any advice from you senior techs??? Please help!
