You are clearly missing the point about using pure ATF in an engine, I will explain it once more then leave you to your "theory" and opinon about it... the anti wear additives in ATF are extremely low, its more like a 0/20 or 5/20 viscosity. What little residual oil is left in the engine after draining does not protect the cam/lifters or other critical wear areas of the engine using pure ATF, it will cause wear to those areas and has LESS detergents than engine oil. That is based on facts, not personal opinion.

The oil wasnt all that "dirty", you said you changed the oil more times than you can remember on this engine... adding any type of flush to oil that isnt really "dirty" and would pass a UOA with flying colors is not ridiculous, its added when its time for an oil change.

Amsoil does NOT use ATF in their engine flush product, where are you coming up with that? Just like most all other engine flush products it is mainly a mix of strong detergents and other petroleum solvents like kerosene, naptha, and others like xylene/toluene.

Use & do what you want, just trying to help you understand what engine flushes are & how they are used and that pure ATF is not doing your engine any favors. Hope you figure out all your noises and can actually get the car to run right at a proper temp. 78w72 out.
