For what it's worth, below is an email response I received from Prestone this morning concerning their Cor-Guard Antifreeze which you can pick up at Walmart (or other stores) for around $9 for a gallon of 50/50 pre-diluted mix. I emailed them back and asked if they would be updating their website to reflect this information, but have not heard back yet.

Good Morning Guy,
We do not evaluate that coolant for compliance with any OEM specification, however it is fully compatible with all coolants meeting MS-90032 and is a suitable replacement for them in any application that calls for a coolant meeting MS-90032. Please let me know if you require anything further.
Sincerely,

To Whom It May Concern,
Does Prestone Cor-Guard Antifreeze/Coolant meet Chrysler MS-90032 specs? I saw on your website FAQ page that it meets or exceeds Chrysler MS-12106, but my 2016 RAM 1500 with 5.7 Hemi engine requires the MS-90032 spec'd antifreeze and so far I can't find any manufacturer who states their product meets that particular specification. Any product recommendation you can provide is greatly appreciated. Thanks!
Respectfully,
Guy
