Larger Aircraft Prist

Asked by: 1822 views
General Aviation, Private Pilot

If I was flying a large corporate jet like a global 6000 or G550, would prist be a good idea to at least keep the tanks clean of antimicrobials. I understand it isn't required for anti-icing because most large jets have tank heaters but in the sense of keeping your fuel tanks clean would it be a good idea?

    Prist as you mentioned is not necessary due to fuel heaters/ heat exchangers on large corporate aircraft. Biobor is usually used as a fuel additive for treating the tanks of aircraft. However you should check with each manufacturer as some will recommend different products.
