I am going to be giving my high mileage 96 Ford 300 a flush in the near future. Can anyone explain to me what the difference is between Auto-rx and Neutra? I get the impression from this board that they will both work in the engine oil and clean deposits and varnish. Is this correct?
I have a local supplier of Schaeffer products so I don't have to pay for shipping. Thought I would give it a try.
