1993 FZJ80, 1FZ-FE engine @ 215k miles. Any thoughts on the analysis? This is the first time I have had an analysis run and the miles on the oil were unknown although likely within reason. Regardless, the 0.0 for Antifreeze make me VERY happy. Somewhere along the way I figure it had the HG replaced. I have since switched over to the Shell Rotella T6 5w40 Full Synthetic.
