Is 'diesel bug' more likely to occur in tanks that are not refilled/replenished often and is it more or less likely to happen with red diesel or diesel from the garage pump?

As I understand it it is in all diesel supplies but it lives, works and plays at the oil water interface so it is more likely to be a problem in tanks where water is allowed to accumulate, although I believe there are a number of organisms which we group together as "diesel bug"
Refueller will be along in a minute to spell it out in detail.

VicS is correct - micro-orgs are present in ALL middle distillate oils ... Lub Oil, Diesel etc.
The one seen usually is the Diesel variety. It comes in various forms and rarely do you only get one type - it's normal for all to be present. That is those that require oil - water interface or at least sufficient moisture content. There are also Sulphur Reducing Bacteria that thrives on sulphur content.
A tank that is static will of course suffer most likely worse contamination than a repeat filled one. But in fact it really depends on supply and whether supply has aged or young organisms in it. You can have a storage tank replenished daily - but if it is from old static supply - you could be transferring dieing or dead bugs to collect in that tank. That's not so bad as it settles out. But if that tank stays stirred up - you are the receiver.
But back to static tanks - yes usually problem would be worse.
Part filled tanks only becomes a problem when tanks sweat and moisture collects. This then feeds water content to the fuel.
Red or Road Diesel ? Depends again on supply and can be either. Red now is significantly reduced levels of sulphur and will continue to fall in UK that is and other EU locations. There is one due south that has at times reverted to the older higher sulphur level diesel - then SRB is more prevalent.
I would suggest that as diesel changes - the problem will be less and less especially if tanks are cleaned / emptied to change to new stock. I would think that if you suffer blocked filters now - it may be a combination of your own tank dislodging age-old crud as mine did, any residues left in shore systems etc. Hopefully it should slowly die out ...

Found an issue the is now quite prevalent in the Baltic where most of the desiel is now bio, up 15% by volume, where throughout the winter if the is left stored, some of these desiels revert to type i.e micro organisms start growing. Also becuase of the different viscosity there can be a problem with the adjustments on the injectors.

Word filter prevents me from posting reply to this ... So keeping it within word filter bounds - where do you get this rubbish statement from ? Baltic States conform to EN / EU specs. in fact more closely than certain long-standing EU members.
How do I know ? I live and work in Baltic blending fuel.
If you have evidence of different - please PM me to discuss so we can identify .....
