The big issue is will diesel by more or less expensive in 6 months. Let that guide you.

My last three boats all had diesel bug when I bought them. Marine 16 et al, gets rid of it as long as you get any water out.
I am inclined to agree with the marine 16 article. Modern diesel goes off. In cold climates I think it separates into layers creating a whole new set of issues.

Compared with the aggro and cost of trying to get rid of diesel bug, the potential for diesel to be a little bit dearer or a little bit cheaper in 6 months time is neither here nor there for me. I'll opt for whatever I think is most likely to avoid that scenario.

There are many opinions on what to do and they have been debated here a number of times over many years with no clear evidence on what is right. Based on my experience over 35 years of diesel engine boat ownership is that there is no benefit in filling the tank.

Use your boat over the winter, mines out in Dec for 4 weeks them back in the marina, we had some amazing winter days out last year, saves on winterising, I do tend to keep the tank filled and treated with Marine 16 so it useable at any time.

1/ If you believe you have water in your fuel try and remove it, I know it's easier said than done in most boats I have sumps I can strip most don't.
2/ Always treat the fuel with a proprietary diesel biocide Marine 16 or Grotamar.
3/ Check your prefilters frequently and remove water whenever you see it.
4/ If the prefilter elements are starting to gum up replace the filters, always keep several sets of spare elements on board.
5/ If you know you have a problem get it sorted pronto, clean the tank, if it's a small amount of diesel dump it and replace with fresh.
Modern common rail diesels are wrecked by water and dirty fuel , don't go there.

I’ve been boating 30+ years, always brim the tanks over winter and occasionally use over the colder months but never had a bug problem.
Also I add the appropriate dose of Fuel Set every fill.

I always brimmed, added Marine 16, and never had a problem.

When you change you pre filter do you top the filter up .

Last winter was with tanks below half full.
No known fuel issues.
Additive used at every refuelling . Present additive is sold mainly as a fuel system cleaner .
Fuel has changed over the years and now has some FAME content and a shorter shelf life than the high sulphur stuff of the past.

Always bear in mind that the point of the article is to sell a product

Has anyone actually had any issues purely related to old diesel breaking down over winter? I've never heard of issues due to old diesel, plenty of issues with old petrol just never heard about diesel.

Yes it isAlways bear in mind that the point of the article is to sell a product
But the amount of additive required is proportionate to the amount of fuel.
So if little fuel is in the tank as per their advice, is not maximising their sales .

Clearly they want to raise awareness of their product, nothing wrong with that. But since running your tanks low in winter doesn't affect sales of their product one iota (except, possibly, negatively), it's rather disingenuous to suggest that it's 'the point of the article'.

Ditto, but it's important to understand that the diesel you buy today is different to what it was 30, or even 10, years ago and react accordingly if necessary.

The best plan would be to use fuel that does not degrade and is not a fossil fuel

Well that is not exactly true. They recommend putting a killer dose into the emptyish tank.
