Prist when and with what to use it

[Cecco]

We use Prist once a month because it´s a good precaution against bacteria growth in the fuel tank (citation cj1+), no matter at what altitude you are flying or at what season. Water freezing in fuel is a thing of the past with
the fuel-to-oil heat exchanger.
