This was the other 2004 coolant sample that I submitted. According to the little prestone tester, this fluid was in better shape than the diesel pickup (5 of 5 balls floating). Obviously there is a lot missing from the hand held tests.
Will be replacing the fluid this weekend with either Valvoline Maxlife or Amsoil coolant.
