I used it on a VAG 1.6TDI engine, I don't know if it did anything for now, as a precaution before a full refill

At the workshop, when I asked which is the best product for cleaning my diesel engine, they told me the antifungals.

I read in detail the documentation of this specific product and of the Super Diesel Additive from the same company, and I couldn't understand their difference. I used it preventively, hoping it helps. The negative aspect is that it doesn't have a dosimeter, the container could be transparent so that you can see approximately how much you are adding. I roughly added half and the other half after 3000km.

Very good! I have been using it for 2 years, filling it up every 3 to 4 times, no problem with the fuel. The best in its category!

It seems to be effective even though I don't have such specialized knowledge. People in the field recommended it to me, so I bought it.

I had to immobilize my vehicle for 6 months and by putting 2 of these bottles (250 ml total) in the 60-liter tank and filling it, I had no problem in the end.
