Product Reviews
“After cleaning the engine stopped smoking I hope the effect will last as long as possible, I plan to use this product also in another car. I really recommend you can use without fear preferably undiluted.”
“Very good product, I applied in toyota 2.2 D-cat. The car did not start on a cold engine only on the square. After applying this product from mixed with a small amount of diesel fuel about 50 ml. The car fires up from a shot. I should add that in the meantime I was adding a little bit of tec 2000 preparation which binds water so the car worked for about 60 minutes before it fired everything that is both preparations mixed together and about 200 ml. Drive oil. I do not know for how long But for me the effect super although I never believed in preparations and measures of this type.”
“I was de-emphasized by a stuttering injector, the car almost always on a cold engine ran only on three throats for a couple of good seconds, after the remedy applied it subsided, the engine operation also equalized.”
“The agent works very well on the system. The car fires up to the touch. Applied after an oil change and a green flush, it has a great effect. I've always been quite cautious about this type of remedy, but once I've been convinced, I can't imagine giving it up now. Marek Wrzos. Katowice.”
“Preparation bought because it was supposed to reduce exhaust emissions and eliminate smoke from the pipe. Its small capacity yes helped to get rid of the stench from the tailpipe, but how to check that there are fewer emissions? It was recommended to me by a mechanic, but you know I want to have the effects fully visible right now.”
“The engine runs a little better, quieter. It smokes less. The difference is noticeable.”
“I recommend a very good measure the car started smoking less and running better”
“Highly recommended !!!”
“Super. You can feel the effect.”
“Tested in an XC60 2.4 D5. I am impressed. After one can directly into the trim, the car burns to the touch again at low temperatures.”
“I feel better that I applied it, I believe it helped, but I have no certainty. Anyway, after a month I can still smell the oil that poured on my engine in audi a6 c5 2.5 tdi. My mistake, the fuel filter when disconnected from the system discharges ON from some pre-pump near the tank, I did not foresee this, for this I got a leak during the whole operation. RECOMMEND !!!!”
“Injection corrections in the renault 1.5 dCi from 0.9 to 1.13 max. The car revived as if it got an extra cylinder, the engine on the road can not be heard at all. Nothing ripples, I'm just shocked. I ran 2 cans on a short circuit. Combustion dropped by about a liter, the wife on the expressway on a distance of 100km done twice went down to 4.3l and she does not drive slowly at all. I recommend!”

How does the Injector Cleaner work?
Effective Diesel Injector Cleaning – you’ll feel the difference immediately
TEC 2000 Diesel Injector Cleaner is an advanced product designed for direct cleaning and unblocking seized injectors in Diesel engines. It works from the first use – effectively removing deposits from injector tips and nozzles, improving fuel atomization and injection flow. The result? More efficient combustion, better driving dynamics, and noticeable reduction of black smoke from the exhaust.
If symptoms of injector wear occur, such as rough engine operation, increased fuel consumption, or difficulty starting the engine, don’t wait for costly regeneration or replacement – use TEC 2000 Diesel Injector Cleaner and restore the fuel system’s functionality.
Is cleaning Diesel injectors with DIC safe?
Yes! The product contains lubricating ingredients that additionally protect the engine during the cleaning process.
The application is complex and should only be performed by experienced technicians or mechanics.

How to use
This product is complicated to apply; only use it if you are a professional.
TEC 2000 Diesel Injector Cleaner should be applied directly to the injector rail. Depending on the engine type, this can be done using a professional injector cleaning device or one of the kits available in our store.
✔️ Do not use the product on a hot engine – there’s a risk of the product boiling.
✔️ If you’re unsure about the cooling system’s efficiency, use the product in intervals.
✔️ Perform the procedure with the engine hood open, in a well-ventilated area.
The effects are noticeable immediately after use.
Note 1: However, if the effect is partial or the injectors were particularly heavily contaminated, it is recommended to repeat the entire operation.
Note 2: If none of the above options is inapplicable, insert the end of the suction pipe from the vehicle's fuel pump into the TEC 2000 Diesel Injector Cleaner can, at the same time, the “return to tank” pipe should also be inserted into the can. The engine should run until the contents of the can are almost emptied. Wanting to get better results in high mileage engines, we recommend extending the procedure for another 20 minutes, using an additional 375 ml can of TEC 2000 Diesel Injection Cleaner.
