- After using the product, I immediately noticed a decrease in fuel consumption by about 2 liters. I think if the result lasts for some time, then an additional plus will be the fact that the remedy pays for itself It is quite convenient to spray inside the collector (I did it right through the damper)
- Decent cost (but I do not consider it critical) Unlike a full-fledged cleaning of the collector, here one can judge only by indirect signs of effectiveness (or an endoscope is needed)
