Just need another 7 or so responses to get us over the 100 votes then I can stop pestering everyone by moving this up the threads.......

Thanks to all those that have responded, results are intersting and I suppose somewhat expected.

I don't treat the fuel. Our Princess 42 has insulated fuel tanks and I think that stops condensation forming. In just over 4 years we have never had any water in our fuel separators and as I understand it without water you won't get the bug. We also keep the tanks full or at least full-ish as we use the boat over the winter months.

PBO carried out a test of twelve diesel bug treatments in May 2011. It's well worth a read.

A few years ago I took my massive 10 gallon tank out to check for the bug as advised by my surveyor. In the bottom I found a gelatinous/fibrous lump about the size and shape of my hand which presumably was the diesel bug. If this had broken up in rough weather it would definitely have caused problems. I had been using some old Sowester fuel bug treatment but it obviously wasn't totally effective.

This year I had to remove the tank to get to a skin fitting and found the bug again but it was only about the size of a 2 pence piece. I have now dumped my old fuel treatment and bought some Marine 16 which performed well in the PBO test.

Yes, I informed the Sealine Forum of it: PBO 534 MAY 2011 Edition, they tested 12 Fuel Bug Treatments, the results were as follows, sorry about the quality but I just took a photo as my colour scanner isn't working....

Depends on your attitude to 'risk,' I suppose. Around the Med we can take on fuel from mini tankers, garages and elsewhere (via jerry cans), as well as from fuel quays: so even at swindlery prices I regard the price of a bottle of Grotmar as cheap insurance.

With my previous boat I regularly dosed the fuel with both Soltron to kill any bug and Forte Diesel Treatment, which is supposed to break down and absorb moisture in the fuel tank, as well as clean through the fuel lines and injectors.

I never had a problem with diesel bug.

With my current boat that I bought mid season last year, I noted from the previous service invoice that there was evidence of black sludge in the fuel filters. Around the same time I read that test on the treatments and changed from Soltron to Marine 16, giving it the recommended dose for no bug.

Than I broke down a couple of weeks ago, with one of the filters blocked and the other almost as bad. I have never seen diesel bug, but there was some slime in the filter bowls and some black floating blobs around 2mm in diameter, that smeared when you touched them.

One bottle of Marine 16 now added to each tank!
