How do u unseize a 340 motor...or any motor

Just wondering about other members experiences. My way was as follows. Removed the plugs poured tranny fluid into the holes and tried to hand crank the motor. Nothing. A mechanic told me to use diesel fuel, not oil, fuel. He said it was thinner and a better lubricant than tranny fluid. Tried that. Nothing. Kept at it. One day I tried hand cranking it and buddy wanted to go for a beer. Don't we all? I said one more try. I gave a good heave on the breaker bar and damn if that motor did'nt break free. And damn if that beer did'nt taste great. Anyone have any different,better ways. To unseize a motor , not drink beer :)
