dude if a 2 foot cheater's bar doesn't do the trick on a drain plug, there's something seriously wrong. Do what the previous suggestion said:
1. apply some good penetrating oil - PB blaster is okay, I've had good luck with something called 3-in-1 penetrating oil (made by the same company that makes WD40 i think).
2. warm up the car (you should do this anyways).
3. use a cheater's bar (2 foot should be plenty). Feel what you are doing. If something doesn't feel right, stop! Last thing you want is a broken drain plug.
You know what, now that I think about this, forget this. Take the car to a dealer or somewhere reliable to get the oil changed. They will open the plug for you and you get an oil change. Switch to synthetic can be done later. If they screw up, it's at least partially on them. Buy a new drain plug and have them install this and discard the old one if the old one doesn't look right.
