Yes. Not sure which oils of theirs definitely don't have 'much' added, but the MaxLife seems to have higher sodium levels for sure. 300-350 ppm seems typical. Which is why it's encouraged to use another oil trying to track a coolant leak. I'm having to get away from their MaxLife 'red bottle' in my father's S-10 Chevy to do just that.
To be clear, I use and would recommend their MaxLife product.
