Umm,
SOPUS doesn't use sodium in their oils, nor does Mobil in M1.
Mobil Super Syn does, as do most Valvoline products.
Nothing wrong with it.
The real marker for coolant in the oil is potassium, but only for those who do UOAs.
The rest would never notice a little misting from a minor head gasket leak.
