If you notice that your engine is running rough, losing power, or producing smoke – don’t wait for the problem to get worse. TEC 2000 Diesel System Cleaner is an effective diesel fuel additive that cleans injectors and the entire fuel system, reduces vibrations, and helps restore engine performance.

Simply pour it into the tank to improve fuel economy – particularly noticeable in trucks – remove water from the fuel that accelerates corrosion and disrupts engine performance, and restore proper fuel atomization for cleaner combustion and less exhaust smoke.

Using TEC 2000 Diesel System Cleaner as a preventative measure ensures: smooth starting even in difficult conditions, restored power and driving dynamics, quieter injector operation with fewer vibrations, reduced black smoke and harmful emissions, and a cleaner DPF that requires less frequent regeneration.

It’s the solution for anyone who wants to keep their diesel engine in top condition.

Product Reviews

“I do this always after the winter I pour into the tank as I already have a reserve that is about 8-10 liters to get rid of water algae and all the impurities from the tank and the fuel system by the way I clean the injectors I leave this reserve to the minimum as I have a range of about 10 20 km that is left about two three liters I fill it to full. after this operation I replace the fuel filter. whether it actually helps It's hard to say It would be necessary to have Two identical cars engines in one drive with this in the other without and see after 200 thousand What is the difference unfortunately Rather few people are able to verify it Certainly it will not hurt and even help”

“revelation, I recommend to every diesel owner I used on 2013 vw touareg 3.0 diesel krzysiek@lomianki k wwy improved engine performance and changed fuel consumption”

“It works for me I have flooded two bmw and a golf the parameters of the injectors have improved as well as the work of them even though they were not worn out I recommend tec”

“The engine “rattles” less so I guess it does something:-)”.

“I already used and it works nice. the car smokes less after flooding but it is not for a long time unfortunately. rather already the fault of the injectors. I use prophylactically every now and then”

“I use this product every so often and can really feel the improvement and quality of the engine. I highly recommend it.”

“The products are REVELATIVE !!!!! I tried many and only TEC2000 really gave concrete results ... I highly recommend >> mainly the rinse but the diesel or oil additives are also great ...”

“Changed oil and all filters, including the fuel filter. In addition, poured Diesel TEC 2000 System Cleaner. after a few weeks of application, it was noticeable that fuel consumption has decreased, not significantly, but it is lower. From the exhaust you can not see any smoke coming out. We will still see how the car will behave when the temperatures are lower.”

“The car after applying the product wavers more smoothly at speed and seems to have more power at low revs. I poured into the tank as the reserve came on and traveled 60 km. The improvement occurred. I recommend”

“The agent awesome 6+ The injectors were so overgrown that the car did not smoke after the injectors were resharpened and this smokes from the shtick even in the cold.”

“The engine began to run quieter and most interestingly it smokes less to the fuel reserve I did 90 km more on the highway. I can confidently recommend this product as it is very effective when it comes to older drive units. I used TEC 2000 in a BMW 5 series e60 525d”

“Some recommend the use of this type of preparation, others advise against it.... I used in 2 cars on average once a quarter, to the tank, the average refueling of 90 l / month, diesel smokes less, gasoline falls less from the ignition and the engine runs more evenly, at idle there were fluctuations in the tachometer. both cars after 390 thousand km.”

When should you use TEC 2000 Diesel System Cleaner?

When the engine isn’t running smoothly

Rough idling, vibrations, or unusual noises often point to dirty injectors. The additive removes deposits, improves fuel dosing, and restores smoother engine operation.

When injectors may be clogged

Dirty injectors are one of the most common causes of poor performance and increased fuel consumption. TEC 2000 Diesel System Cleaner reaches the injector tips and helps restore proper function.

When there’s carbon build-up or moisture in the fuel system

Water and deposits interfere with combustion, cause rough running, and increase fuel use. The product binds water and dissolves deposits, restoring engine efficiency.

When cold starts are a problem in winter

Diesel engines struggle in low temperatures due to poor fuel atomization and moisture in the system. The cleaner improves fuel spray and removes water, making cold starts easier.

When power is dropping

Clogged injectors fail to deliver enough fuel, reducing throttle response. This cleaner optimizes combustion, restores power, and improves overall performance.

When the engine runs unevenly

Irregular operation often means incorrect fuel dosing. Regular use of TEC 2000 Diesel System Cleaner restores smooth engine performance and reduces vibrations.

After filling up with poor-quality fuel

Cheap or contaminated fuel can quickly lead to injector problems and deposits. This additive neutralizes the negative effects, protecting the system and restoring optimal operation.

TEC 2000 Diesel System Cleaner

How to Use

Using the product couldn’t be easier – just pour it directly into the fuel tank. It starts working from the very first miles, cleaning the injectors and fuel system as you drive.

If you’ve previously used low-quality additives, it’s recommended to change the fuel filter before the first use of TEC 2000. This ensures maximum effectiveness and prevents blockages from dissolved deposits.

For long-term protection and injector efficiency, it’s best to use the product twice a year – ideally in summer and autumn, when temperature changes and fuel quality most affect engine performance.

TEC 2000 Diesel System Cleaner is powerful yet safe – the engine can even run on the cleaner itself, though its intended use is as a fuel additive. This guarantees that it reaches even the most difficult-to-access parts of the injection system, cleaning precisely where it’s needed without risk to the engine.

Dosage:

Preventive use (optimal):

  • Passenger cars: 1 can (375 ml) per full tank – use twice a year
  • Vans: 1 can (375 ml) per full tank – every 20,000 km

Emergency use (e.g. injector problems, water in fuel):

  • Pour 1 can (375 ml) into about 25 liters of fuel (reserve tank level). This creates a stronger cleaning concentration.

The product can be used in a wide range of diesel engines. For preventative use, the recommended dilution is 3–10 ml per liter of fuel.

1. Pour the preparation into the fuel tank

If you suspect that there are impurities in the tank (such as water or paraffin), you can use 1 can (375ml) ~25 liters of fuel.

2. Fill up

3. Burn the fuel with the additive

After applying the product, we recommend replacing the fuel filter.
