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.

The previous thread was posted on 2/22. The OP of this thread had probably already sent off his sample by that point.

Yep, that's precisely what happened.

Funny how all your values are higher than the other VOA....still a very thin 30-wt., though.

A trend I have noticed for years with VOAs from Blackstone...

I told the OP in the other thread the same.
