This is why it is useless to apply any type of penetrating oil on this type of plug. 1.) As mentioned, the threads are already sitting in oil. 2.) That plug has an O-Ring seated in a flange to seal it. So no penetrating oil you apply will ever get to the threads from the outside. The O-Ring itself will prevent it.
Get the best fitting and longest breaker bar you can find, then put yourself SAFELY in the best position you can get yourself into in order to administer maximum torque, and something will give. Just hope it's the plug. (From your picture that casting already looks cracked on the left side going to the plug).
