I recently started getting reports back in our Tahoe with high levels of sodium. Since I recently switched from the SM to SN version of this oil and there was not a noticeable coolant loss I was hoping it was from a formulation change and not from coolant!. Glad to see the suspicion confirmed by two recent VOAs on this oil.
