It is very possible that stress is causing these symptoms . Either way I ' d get a second opinion because it would give you peace of mind <| sep |> Green room <| sep |> sorry man we filled up . <| sep |> A voice of reason . Good looks on the post man . <| sep |> Well I won ' t know for sure unless I ask , no ? Thanks a lot ! That was exactly what I was looking for . <| sep |> not true check amazon <| sep |> I ' d appreciate it too if you could find a source on this that isn ' t anecdotal . I work offshore and we recently had to empty and decontaminate our entire helifuel system as there was approximately 20 ltrs of fresh water contamination present inside . Likewise , with our diesel bunker tanks , any water contamination is taken very seriously . We have centrifugal purifiers and separators as well as numerous filters in the system and on the engines . Water contamination can quickly render a tank of fuel useless as bacterial contamination can occur . This is a nightmare to get rid of and turns fuel into a watery frogspawnlike goo . Once empty , the tank will require treating on every surface with biocide . Even then it ' s not a guaranteed fix . I hope I ' m not coming across as disrespectful but coming from an industry where we look after our 33 year old engines , I would imagine that a Navy would treat it ' s aircraft infinitely better . If we get bad fuel , it goes dark and quiet on board . The same situation will be much more serious in an aircraft .
