My father runs it in his Jeep liberty and has for 210,000 miles with changes of between 7 to 10k and a P1 or Fram filter the silver mid range one I can't recall what they call it right now. I run ST syn in my 4Runner quite often usually in winter for an 8k oil change or when I tow my 5,000+lb camper in the hot summer and a 6k change with a P1 filter. I now have 170,000 miles on it and it runs great so ST must be good.
