Regarding Prist very few times has anyone in the modeling community brought up this additive. In North America it is optional to have Jet A with or without. However I found out today that Pratt & Whitney advoacates the use of Prist in there turbines.

One last thing I have seen fuel tanks that used Prist and they are pristine. But in talking with several Prist users today I found off that it no longer guards against bacteria growth.

The above comments were made with full size axial flow turbines and full size aircraft not sure where the model community would fit in this Prist issue since we typically drain the tanks except the UAT or hopper.
