one of the 3 best BRANDS for car cleaners/additives!
IMPORTANT to put it in a nearly empty tank and then fill up so it mixes better. Even more CRITICAL and useful afterward to go for a drive with somewhat high revs. find the exact type of your engine & if you have a DPF catalytic converter etc. depending on the age I don't know.....and ask g00gle's A.I. how to go for a drive on the highway at steady revs (usually in 3rd or 4th gear if it's MT). DIESELS do not want very high revs. if you have a DPF it needs more time especially in winter because it needs a higher temperature to "burn off". ATTENTION start first for a few minutes until it reaches the desired temperature (usually the COOL light goes off). at idle don't leave it for more than 30'' in modern engines.
RESEARCH IT to see

Unexpected improvement during cold start, it seems to work in between, I tried it on two cars with diesel engines, one had an issue during cold start with noticeable improvement and the other had shaking at idle, again with noticeable improvement from the first use. I will add it again at the next fill-up for further improvement.

from the first fill-up and after 400 km I saw a big difference in the car, the engine is very responsive and strong acceleration, clean and quiet operation

it definitely did its job...in an instant engine stalling while driving, with the first can I used the problem was magically solved

After cleaning the injectors in a full tank (60 liters), I added a package! I don't know if it's the cleaning or this, but the consumption has definitely dropped. I believe it has more to do with the cleaner than with the cleaning of the injectors. dci 1.5 Renault

I noticed smoother engine operation on cold start. I will return when I add the second bottle that I purchased.

I tried it on an Audi Q3 2.0 TDI with 160,000 km and generally rough engine operation that I didn't like. I filled up a full tank and added the injector cleaner. Within 200 km, I noticed smoother engine operation with reduced combustion noise and decreased vibrations inside. I continued with a second bottle on the next fill-up and I think the engine operation improved a little more. I recommend it and will try other products from the company.

It works. If the injector nozzles are clogged. It's good. With the adulteration that all gas stations do, it's a good idea to pour a bottle into the tank. I saw on YouTube some Arab guys doing a cleaning directly after the fuel filter on clogged diesel injectors and it cleaned them. With 500 ml

I added it to a 2010 Lexus IS 220D with 300,000 km in almost a full tank with 65 liters of diesel. It significantly reduced the rattling, increased the torque and acceleration of the car, and slightly reduced fuel consumption. Overall, it made the engine quieter and more economical. I have driven over 2000 km since then with the same favorable results. I am satisfied; the product is very good, and I will continue to use it every 3000 km

I did not expect to see a difference and it is worth mentioning that I did indeed notice smoother operation, with fewer vibrations and possibly reduced consumption, in combination with overall service.

Very good especially when you apply two layers of filling, apply it continuously three times and then use the x3 feeding system cleaner, it does the job, but not on the first application.
