Bought as a diesel preservative
Bought as I use diesel powered hot jet wash so keep 20 litres in a Jerry can which can be sitting for months, I read that diesel can grow bacteria which breaks the fuel down into products harmful to the engines. This product stops this from happening and prevents the byproducts of diesel deterioration clogging up the injectors 1 millilitre treats 1 litre of fuel so it’s cost efficient- and goes a long way.

Used for storing diesel in jerry can.
I think its an essential product to add to my jerry can of diesel. Good brand and product. Unfortunately like most other things its a bit pricey for the size you get but nevertheless worth it as a little goes a long way! The petrol one is also very good. Will buy again and again.

Early Days
Purchased this product, for my Kubota tractor and have found it very easy to use, with clear instructions as a fuel additive but too early to say just how effective it is

Le produit semble efficace et a permis de rendre plus fluide un GO stocké dans un réservoir de bateau. Si le moteur avec sa pompe d'aspiration puissance ne posait aucun problème, la pompe du chauffage central WEBASTO qui est sous forme piezzo n'aspirait plus correctement. Après traitement tout est revenu dans l'ordre ce qui valide le produit.

Consegna 1 giorno prima del previsto, il prodotto l'ho messo perché la mia auto era ferma da 5 mesi e il gasolio stantio aveva sicuramente proliferato mucillaggini che ostruivano il filtro, infatti andava un po' attappata nelle ripartenza. Ho messo l'additivo come consigliato e dopo 500 km va libera e sciolta. Quindi devo dire che il prodotto funziona alla grande. Aggiorno la recensione 20 ottobre 2020, la macchina di un mio amico era rimasta ferma 6 mesi e dopo averla rimessa in moto andava malissimo, auto abbastanza vecchia, micra 1.5 dci con 300.000 km, neanche dopo 200 km smetteva di sobbalzare e fumare come una locomotiva e andare a scatti accelerando. Gli ho messo 5ml di prodotto e dopo un paio di giorni è tornata a marciare regolarmente. Quindi ulteriore prova che il prodotto fa quello che dice.

Impeccable mon réservoir de bateau fait 2200L gasoil. Ce bidon peut me faire 2 hivernage antibactérien. À diluer dans un bidon de 5l si vous avez déjà fait le plein.

prodotto molto ben confezionato, di facile dosaggio! Lo sto usando in via preventiva nel serbatoio del carburante del mio camper dove spesso il gasolio rimane fermo per mesi! Sull'efficacia non saprei pronunciarmi visto l'uso preventivo! Sono convinto però che si tratta di un'ottimo prodotto

J'ai eu un problème de sur le circuit de carburant de l'un de mes 2 Yanmar TD causé par un microbe dans le GO. J'ai peu navigué depuis un an sans refaire le plein: donc humidité favorisant ces dépôts graisseux crèmes et surtout le retour GO provenant de la pompe. J'ai nettoyé le réservoir, changé filtre et pré-filtre, c'était mieux avec "le traitement agressif" sans pouvoir monter complètement dans les tours. Puis finalement j'ai remplacé les conduits par de la durite neuve et c'est parfait. Mais à présent je mets automatiquement un dose de traitement d'entretien lorsque je remets du GO. Mais mettez ce produit sans attendre l'ennui que tous auront un jour, comme un autre ami cette semaine....
