I have been using it for many years (VW Golf, Audi A3) and I have no problem with the DPF. I don't wait for it to fail before I use it, like some people do, and then they say it didn't do anything... But the main thing is that the car is driven on country roads and not just in the city; diesels need to run. If you have it in stop-start-first-second driving, no matter how many cleaners you use, they are useless.

There is a feeling that it pulls better but only for the time until you refill the tank. I use it preventively without knowing if it really helps; however, the only thing that is certain is that after 1 year, no problem has been created in the DPF

I used it on the recommendation of a mechanic because it was smoking on startup and had a strong odor. After using it for about 120 km, it stopped emitting the smoke it was producing and the engine no longer rattles on startup. It has nothing to do with other cleaners that I had used unnecessarily. 2014 car.

I have been using it for a long time preventively. It seems to help. The main thing for me is to let the car regenerate whenever it wants without cutting it off and stopping.

I have been using it for several years in a Hyundai i20.
It definitely helps and you always put it preventively.
As for the dpf, in order to prevent the warning lights from turning on and clogging, you should drive at around 2800 rpm for half an hour every 1000 kilometers.
Diesel engines are meant for long distances on national roads, not for going from home to the supermarket and from the supermarket to the café.

I had the light on for three months, I threw a bottle into a reservoir at the end of the reservoir, the light went out. It has been three weeks

It was giving me a DPF fault. I installed it and the fault stopped. It did the job. I have been driving short distances for a year now.

I used it when the DPF light came on in the Hyundai i20 (2017). I drove from Attica Road Spata to Thriassio at 3,000 RPM in 4th gear. The light didn't turn off immediately, but the next day there was no indication. It seems to have done the job, but for how long, time will tell. "My review didn't seem useful to the mechanics here at Ferrari with their punto-saxo-rally. They wanted me to write that I put it in the car and it cleaned the engine, the living room at home, the dishwasher, and the teeth of a friend who wore braces..."

Satisfied enough.

The consumption decreased slightly and the sound changed. I believe it has done what it promises, although time will tell.

Whether it was installed or not, it's the same thing, the light never turned off even though I drove many kilometers at high speeds. The filter went for cleaning afterwards, but I will continue to use it preventively and see what happens.

In the decade of diesel, it did an amazing job from the first kilometers! I filled it up with a full tank and drove a little higher than usual, around 3,000-3,500 RPM, plus I had a trip where it worked for over 300 kilometers on the highway! The car's performance changed as if it had been unclogged and the sound also changed slightly. I will do it again in 5 months! It's worth doing!

UPDATE 11/4/2023
I went for a DPF cleaning because the warning light wouldn't go off no matter what! Eventually, the filter broke internally and we had to replace the DPF.. (148,000 km)
The mechanic and the shop where I went for the filter cleaning told me that the cleaning agents have a big responsibility for the damage and as advice, they told me not to use any cleaning additives again! I won't change the stars because it did work for a certain period when I used it.. However, I definitely won't use it again and I'll just go for a cleaning at 80,000 km!

I didn't believe it would work, but it did! It was used on a 2010 Mercedes Sprinter Diesel that had the DPF light on and wouldn't turn off even with high-speed driving on the highway... I emptied the entire bottle into the fuel tank and filled up with Shell V-Power Diesel. After 30 minutes of continuous driving at high engine speeds (2500-3000rpm), I stopped and turned off the car. When I started it again, the light had turned off and the car's performance had improved!

Very good product. As the owner of a diesel car from the 2000s, I had never used a DPF cleaner before and I am very satisfied because the engine sound has changed (it used to make a rattling noise at low revs) which stopped after the first few kilometers. I can't say for sure because I only used it yesterday, but I think the car's performance has improved slightly as well.

Very good product, it does what it promises. I generally use other cleaning products from this specific company, they are among the top
