I used it after a rattle in a diesel Qashqai. I put it in, filled it with enhanced diesel, and left for the highway. Now it works perfectly

As long as it is inside the tank and until it runs out, the difference is really noticeable for me; in the next refuels, I see a drop again, but you can't use it continuously. Logically, without being an expert, it must be our diesel.

Opened a supply tube that had been narrowed by fungi and had minimal flow within a few hours, with a ratio of about 1:300.

The mechanic who services my Yaris 1.4 diesel recommended it to me, so I put a 375ml bottle in after each service into a full tank. I didn't have any problems, of course, just as a precaution.

I installed it in a Clio IV 1.5 DCI stage 1. I have used many cleaners, this one was among the few that actually worked. The car became more responsive, holds pressure at high revs, and is quicker. Also, the soot levels in the DPF rise much more slowly.

The best product on the market by far does everything it promises. Five-star top product

It is the best out of all the ones I have tried on my tractor, where the oil often gets sticky and clogs. Without exaggeration, it saved me.

Unbelievable product, solved the problem I had when I started the car every morning, it would turn off. Now, I filled up the tank with a full bottle and went on a long trip, and to my surprise, today I started it and it didn't turn off. It saved me a lot of money at the repair shop for only 13 euros.

It does what it says... Check engine light was on and I had to visit the repair shop 2 or 3 times, but even the mechanic couldn't solve it and told me that the brain was reading for a clogged tube. After a 400 km trip with this specific product, the light went off and never turned on again.

I applied it to a FIAT DOBLO 1.6L DIESEL EURO5, and it worked!
During cold engine starts, it made a strange noise with a lot of shaking as if one cylinder was not working, so I assumed that a nozzle was clogged. I put the entire bottle in a full tank and I can say that it did a good job!

Excellent product! I recommend it for petrol engines, it really cleans and the car performs well
