I just had a UOA done and found high levels of potassium (and some sodium) in the oil.
I'm trying to get some idea of how much coolant that level of potassium represents. There were 42 ppm Potassium, as well as 24 ppm of sodium (the previous UOA done immediately prior to this OCI, found 0 ppm potassium, and 10 ppm sodium).
I searched and didn't find a VOA of Toyota Pink Super Long Life Coolant.
(1) Has anyone posted one here?
(2) Barring that, does anyone know the upper limits of how much potassium is used in coolants?
