Beating the cr… out of diesel bugs


While searching for possible ways to beat the cr… out of the diesel bugs, I by chance came across a rigorous test of diesel fuel additives undertaken by the reputable German Segeln Magazine 3/2009 ( As the test is not freely available, I purchased it to gain access to the results. According to the test, most diesel additives cost a lot and do not do the job, i.e. a waste of precious cash. However, one product stood well up to the test – Grotamar 71. 
This is what the test stated:
In den von uns gewählten Dosierungen wirkte das Mittel perfekt, beide Proben waren vollständig keimfrei. Die Dosierungsangaben sowohl für Schock- als auch für die Permanentdosierung sind auf der Flasche zu finden, allerdings sehr weit gestreut (Unterschied mit Faktor 20!). Mit der Frage, welche Konzentration denn jetzt die richtige ist, wird der Nutzer etwas allein gelassen. Wir haben uns deshalb für einen realistischen und (ab-) messbaren Wert von 0,05 % für die Permanentdosierung entschieden. Die Warnhinweise sind vollständig, der Verschluss gesichert
Google translate for what it is worth:
At the doses we selected the remedy worked perfectly, both samples were completelysterile. The dosage information for both shock and for the permanent dosagecan be found on the bottle, but very far spread (difference by a factor of 20!). The question of what concentration is it nowthe right, the user is left alone fora bit. We have therefore opted for a realistic and (ab-) measurable value of 0.05% for the permanent metering. The warnings arefully secured to the closure



What now?

Question: Vessel bought – what now?

Answer: Probably 1001 – not major, more hopefully rather minor items being added to the To-Do list…….
