With this additive mixed with diesel before winter storage, your engine restarts well after months of inactivity and the fuel tank is clean without bacteria and deposits.

Ordered again

This is the fifth liter of this product that I have used.
I used to have problems with the diesel in my boat, but that was a while ago and I would definitely recommend the additive.
I don't need to mention the fast delivery, which is obligatory with SVB.

Does what it should

So far everything is fine, I strongly assume that it will stay that way since all dosage instructions have been followed

Satisfied

In my opinion, at least the diesel plague hasn't gotten any worse. Of course, the stuff doesn't dissolve the clumps of mucus, so it's difficult to judge whether the microorganisms are actually dead. But the boat has been running with diesel pollution for many years without any problems. I also filter out the clumps of mucus every year and use Liqui Moly.
