amazing, some small scratches disappeared always in combination with the grey one in every refill. The first time I used 200ml it works like all their products, now I want to try the gold one but unfortunately I found them through Skroutz

It did the job for me, the fuel tank gauge after many years of inactivity was not showing correctly on a diesel tank, after consuming almost 1 bottle it started to show correctly.

The best diesel cleaner by far, I had an issue with the pump due to the sludge that had accumulated over the years, resulting in the fuel gauge fluctuating with each refill without knowing how much fuel I had in the tank. I poured the recommended amount and after a 200km trip, the gauge now shows the actual amount of fuel in the tank. Additionally, the "irregularities" and jerking at idle completely disappeared. Get it yesterday, guys, you'll be saved.

I bought the clear diesel because one of the cars was losing revs at idle and not responding well to the gas, after using clear everything was fixed!!

Excellent sanitizer for the tank and fuel system, I had a problem with smoke and clogs in my 2008 Ford Ranger and as soon as I used it, the difference was noticeable. I use it regularly (every three months) and also use the diesel kleen from the same company. I also use clear in the diesel tank I put in the tractors because it is a stabilizer. Bravo to the Americans!

I use it every 3 months in combination with power service diesel kleen on the 4 professional vehicles I have, and I haven't had any problems with fungi so far in the last 3 years. 3 out of the 4 cars cover a lot of kilometers. I have also used it on the oil boiler at home because it was making a noise at regular intervals, and after 1 day the noise stopped.
