When do you use Prist?

Falcon 2000 does not require the use of prist. We have a fuel/oil heat exchanger..

The G-IV does as well, but I have observed some pilots ordering "with." I'm going to call SAV tomorrow to get more information.
 
The Pilatus POH requires an anti-icing additive (hasn't actually been Prist for years. It is typically FS2.) anytime the OAT is below freezing at any point during the flight, which is every flight. If you would like to review an accident case that highlights the need for fuel additives in the PC-12, try this one. http://www.ntsb.gov/doclib/reports/2011/AAR1105.pdf
 
Just to add the metro does have a fuel/oil exchange, however according to our Op's Manual, it still goes in.
 
The Citation Ultra requires it, so we use it. Our Bravo and Encores do NOT need it.

The C650 does not require it, but we get enough premixed that it takes care of the anti fungal function.

To add, the PC12 has an Oil/Fuel heat exchanger. Our company policy is to use it at all times.
 
[h=2][FONT=Arial, Helvetica, sans-serif]"What will PRIST® Hi-Flash™ Fuel Additive do and what will in not do?[/FONT][/h] [FONT=Arial, Helvetica, sans-serif]PRIST® Hi-Flash™ is an aviation fuel additive that is designed to prevent water from freezing and thereby preventing fuel starvation in-flight. [/FONT]
[FONT=Arial, Helvetica, sans-serif]When applied correctly, in conjunction with the fuel being maintained correctly, PRIST® Hi-Flash™ will stay in solution indefinitely. PRIST® Hi-Flash™ will not change the freeze point of fuel; it simply encapsulates water droplets that form in fuel, altering their freeze point. [/FONT]
[FONT=Arial, Helvetica, sans-serif]PRIST® Hi-Flash™ is not a “tank cleaner” or a “fuel purifier”, it will not eliminate water nor will it replace the need for good housekeeping of fuel which requires daily sumping and removing of water and particulates. Lastly, PRIST® Hi-Flash™ IS NOT a biocide and it will not “KILL” microorganisms."[/FONT]
