I am trying to warn people there are additives that will cause harm to those that care. I keep my cars for many years so yes I am more anal than most as to dumping something and hope. I expect my cars to go 200K miles or more without mechanical failures. I prefer boring over waiting and paying for repairs, some are obsessed with thinking they are smarter than the designers, I'm not. Old Chinese curse, "May your life be interesting". I have had all the "interesting times" with service issues I want in life, you are welcome to them to write your own book. I will stick to Ford, Mountune and Ford performance to insure no emission fails, warranty issues or reliability issues. To each their own.
