Oh dear....... bit of a mess......I suspect this is more to do with fuel instability than bugs such as those treated by biocides.
This is an interesting note from BP on problems that may be experienced during the storage of diesel oil
It seems fuel contamination falls broadly into 2 groups....Buggy bugs. and stability problems and many companies lke Startron have two products with each aimed at the particular problem. I don t think they would recommend Biocide for this one.. More likely to suggest.
However if the problem is buggy bugs requiring a biocide then this one would be the way to go.
It would appear from the BP note that water is a problem with both and every effort should be made to remove all water from the tanks. Something which is
almost impossible on many boats.
Appparently fuel instability is becoming more of a problem which I suppose is indicated by the number of posters in these forms who talk about using Starton Additive.
Oh well Stewart is going to have fun with this
Eastern Scotland and beyond.
