Transmission fluid mixing oil
no but you can add a little to the oil with out hurting anything no more than 1 qt transmission fluid to 3 qt oil
Only use it as emergency, You can use 1 qt to help lifters free them up. Before an oil change 1 qt run for 30 Min's then change oil. 15 yrs of auto mechanic work seen and done this many times.
NO!!! Transmission fluid does not have the same lubricating qualities as engine oil. Adding it to an engine will quickly destroy the bearings! I have heard of pouring transmission fluid down the carb while the engine is running to free stuck valves, but I wouldn't recommend it. JMHO.
