Hello Indy. I have followed your dilemma on 4 or 5 forums. I think what everyone is trying to tell you is with an engine in the shape yours is in, it really won't make any difference in the weight of oil you use. If you use thinner oil, it will burn it faster and cause problems if the oil is not checked really often.. If you use thicker oil, it will be hard on the engine tring to start and could cause the engine to destroy itself sooner. So use whatever oil you have been using and start looking for an engine or possibly another vehicle for the future. Good luck with the car. Hope it makes it through the winter for you.
