I am working on the same thing. although I could not find any specs on it, I assumed it was a metric car.. the 17mm fit my car fairly well, but after applying 110 lb feet of torque (with bar on L shaped key) it would not budge. the drain plug is loose and still in so that it not a problem. the last resort that I know of is to use a heavy chisel, grinding the edge so that it is not sharp and hitting the steel plug on the edge making a dent. THEN moving the tool to a 45 degree angle at the 5 o'clock position and striking the tool sharply with a 2 lb sledge hammer. this action will destroy the steel plug in short order if it does not break loose soon. This is where I am at now unless one of you posters have been there and done that. thanx
