Prist vs Marvel Mystery oil

[Eamon]

When fueling the Caravan, I always order w/Prist.

It got me thinking about MMO

I searched the website for Prist & found this......

Fully Authorized
Prist Hi-Flash anti-icing aviation fuel additive is authorized by the United States Armed Forces under Military Specification Mil-DTL-85470(B), and by the ASTM under Standard D4171 for use in civilian jet fuels as a fuel system icing inhibitor. As part of its ASTM approval process, the formulation of Prist Hi-Flash additive was reviewed and approved by turbine engine and turbine aircraft airframe manufacturers worldwide.

With that all said and done, Do you need authorization to put MMO in a plane?

Keep in mind I have never even been in a Carryvan let alone worked on one of their engines but if the engine mfg says its accepted and the additive people are all for it, I would think you are good as long as your company/maintenance personnel agree with it.
What advantage do you see to changing? You will have to mess with calculations and cans & such, instead of just telling the line guy "Jet A with Prist, I'll be inside getting breakfast."
