Product Reviews
“He did a good job. It restored compression on two cylinders by 3 bars. He did a great job of dissolving the oil and dirt in the engine. Oil was changed 2000 km and I did a flush on the pistons / in the oil , what I drained looked like tar something like this I have never seen. I recommend the product.”
“I bought two bottles because the engine has 220,000 km. One bottle I poured in the old oil and after 20 min of work I poured out the oil and changed the filter, the second bottle I poured in with the new oil and again the engine worked for 20 min.After pouring out the second time the oil which was black as tar I again changed the filter and poured in the right oil. I heartily recommend because everything looks like from the factory carbon build-up dissolved!!Compression improvement on the valves significant almost factory!”
“I do not hide that I approached this product very cautiously, not giving faith in such a miraculous action. After adding to the old oil, which had traveled about 9,000 km and the color dark, I waited 20min the engine worked at idle without any strange symptoms.Changing the oil and, of course, the filters pouring fresh oil the effect is that after driving 300km the oil is still light and the engine spins more nimbly.”
“Hello I will share my opinion of TEC2000 Engine Flush PREMIUM I have been using for a very long time I own from new from the showroom Toyota Avensis 2012 year station wagon 2. 0 d4d 126km 1ad tv I change oil every 10000 km max before oil change I go to the expressway because from me to the road is about 3 km I drive 25 km one way and 25 km the other way I have a canal at my place on the plot so I change oil myself when I come from the road I put the car on the canal add flush I leave the engine on for 15 minutes drain the oil and leave the car for about 24 hours on the canal after 24 hours pour new oil to which I change oil is of course MOTUL 8100 X-.

“Good product, cleans the engine nicely, the oil in the diesel after a few thousand continues to be less than pitch black.”
“I am mega satisfied with the results. I have been using the products for some time in various cars no matter whether gasoline or diesel. They have never failed me yet. I recommend them to everyone.”
“Tested on their cars Nissan Patrol 2004 and BMW 318i 2012. product I recommend in bmw after the first rinse light oil in Nissan after the second rinse light oil, well and engine work better, guys on FB cool videos send, you can see yourself the comparisons.”
“Engine Flush works as it should, I have safely used it for a long time in many cars, customers come and want to pour it, they can see and hear the differences in their engines, the best comments are “Michal how come my smoke stopped after the oil change?” recommend it to everyone!”
“I use regularly at every oil change in my VOLKSWAGEN PASSAT B6 2.0 TDI-CR DPF 140KM 103kW well and I have to say that in our base we have no other model as failure-free as this VW with flush.”
“A very good quality product. My skepticism about flushed kept me away from it for a long time - which is a shame. It wasn't until a mechanic recommended that I use this product that I saw a significant difference. The engine now runs evenly, and the amount of sludge that fell out of the engine was a huge shock to me. The product is highly recommended.”
“As for this product, the flush can be said to be one of the more effective products. The product cleans the interior of the engine well, although the effect is not noticeable from the very beginning. I drove about 200 km and was only able to feel a significant improvement. The engine runs evenly, does not jerk and does not burn out. I am glad that I came across this very product.”
“One thing is for sure, the oil after using TEC2000 has a different consistency. It is more flowing and if it works as on numerous videos and raises the compression additionally then only praise:) I for sure will come back for TEC2000 products. I sincerely recommend.Tomasz”
“I don't remove the oil pan to see how the product cleans but after applying and changing the oil with new oil for a long time the oil is clean and the car is very purged . During the flush you can clearly hear after a few minutes that the engine starts to run quieter . Injection flushes are already waiting .”
"Super produkt. Na początku czytałem opinie , pierwszy raz zastosowany do Renault Master 165dci (przebieg 600tys). Po zastosowaniu płukanki silnik wyciszył się na zimnym silniku , ogólnie poprawiła się kultura pracy. POLECAM"
“The flush really works! I use it at every oil change because I do short runs. I previously used a competitor's product (LM) and was also satisfied, but Tec2000 seems stronger. I highly recommend it!”
“Great product I have been using for a couple of years for every oil change every 10,000 km. The oil always comes off pitch black and thinned which makes it easy for all the old oil to flow out.”
“I have already applied to the poorly rated TSi1.4l 140 hp engine.Effectively quieter engine operation and a noticeable improvement in the dynamics of the car.However, let no one in their right mind count on the rinses to bring the 'dead car' back to life.”
“The best wash for car engines, I did a test on a couple of other rinses and I was shocked how this product handled the dirt even in test conditions , in the engine itself you can see with the naked eye after removing the valve cover how it handled the sludge, I recommend rinsing the engine at low speed even 30 minutes”

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.

FAQ
Frequently Asked Questions
What is the composition of TEC 2000 Engine Flush?
The product is based on four key ingredients that together create an effective and safe formula:
- Modified toluene (C7H8) – the main cleaning agent with an elevated boiling point and modified structure, safe for plastics and seals.
- Gentle ester solvent – a mild, organic ingredient that supports the dissolution of deposits without risking engine damage.
- ZDDP – anti-wear additives that protect the engine throughout the cleaning process.
- Hydrocarbon base – facilitates the transport and distribution of the other ingredients throughout the system.
Remember: the flush works only while the engine is running at operating temperature – its components must have the proper conditions to effectively dissolve carbon and deposits. Unlike kerosene, TEC 2000 doesn’t just "peel off" contaminants – it dissolves them, reaching deep and working precisely.
Can TEC 2000 Engine Flush be used in both gasoline and diesel engines?
Yes! The flush is suitable for all types of internal combustion engines – gasoline, diesel, and gas. It can be used in passenger cars, motorcycles, trucks, or boats. The only exception is two-stroke engines – the product is not intended for them.
Does the dosage differ depending on the type of clutch?
Yes, the dosage depends on the type of system:
- For dry clutches: 1 can (375 ml) for 4–5 liters of oil.
- For wet clutches: 1 can (375 ml) for 5–6 liters of oil.
Can the flush improve engine smoothness?
Yes. Many users notice that after the first use, the engine runs quieter, more evenly, and responds more quickly to the throttle. Cleaning the oil system eliminates causes of knocks, jerks, and vibrations.
Does the engine flush contain molybdenum or Teflon?
No. TEC 2000 Engine Flush does not contain molybdenum or Teflon, making it safe for the engine’s precision parts.
Does the flush contain sulfur?
No, the formula is completely free from sulfur compounds, which is important for engines with a Nikasil coating.
Is TEC 2000 Engine Flush safe for Nikasil coatings?
Yes – due to luck off sulfur in the formula, TEC 2000 can be safely used in engines with a Nikasil coating.
Can using the flush damage the DPF filter?
No. During the engine’s operation, the product does not produce soot, so it does not negatively impact the diesel particulate filter (DPF).
Can you drive the car with the flush in the oil?
We recommend following the usage instructions. The product works within 15-20 minutes, so there’s no need to extend this time.
Does TEC 2000 Engine Flush work in any engine, regardless of mileage?
Yes, the product can be safely used in engines with both low and very high mileage. In older units, it can have particularly noticeable effects because it effectively removes long-standing carbon and deposits.
Can the flush be used with any type of oil (synthetic, semi-synthetic, mineral)?
Yes. TEC 2000 Engine Flush works independently of the oil type – it can be used with synthetic, semi-synthetic, and mineral oils. It does not affect their properties during the cleaning process.
How much engine flush should be used?
The standard dosage is 1 can (375 ml) for 4–5 liters of engine oil in cars or 5–6 liters of oil in motorcycles (with a wet clutch).
Should the engine be cold or warm when applying the flush?
The flush should be applied to a warm engine that has reached operating temperature (about 60°C). This is crucial for the effective action of the product.
Does TEC 2000 Engine Flush make sense?
Yes, especially for engines with high mileage or those working in difficult conditions. According to user feedback, the engine flush effectively cleans the engine and restores better working parameters. It is particularly recommended for city driving, where oil doesn’t reach optimal working temperature.
How does the engine flush affect the turbocharger?
TEC 2000 Engine Flush is safe for the turbocharger. It effectively cleans deposits from the turbo, which can improve its performance and extend its lifespan. This is a key advantage, as contaminants in the oil can damage the turbocharger bearings.
Is it better to flush the engine with a specialist flush, diesel, or kerosene?
Definitely use a specialist flush like TEC 2000 Engine Flush. Unlike kerosene or extraction gasoline, the flush contains anti-wear additives and doesn’t damage seals. Using improper cleaning agents can lead to serious engine damage.
How often should the engine flush be used?
Many users apply the flush with every oil change, typically every 10,000-15,000 km. This is particularly recommended for cars that primarily drive short city distances.
Why is the price of the Engine Flush higher?
The price is a result of its quality and technology – this is not just any cleaning agent, but the result of years of research and testing. Unlike cheap alternatives, TEC 2000 does not damage cylinder surfaces, seals, or turbochargers. It is used in motorsport, and its production in the UK ensures consistency and reliability.
Is the engine flush safe? Have there been any reports of engine damage after using TEC 2000?
