Product Reviews
“This is the kind of product I was looking for a long time this additive refines well and binds moisture in the tank, I have already poured it about 2 months ago and the effect for me is visible greetings!”
“Significant improvement in engine performance. Highly recommend.”
“I will try again in a while. So far the effect is good, but not ideal. The reason most likely lies in the fact that the car is 24 years old and probably no one has ever cleaned the fuel system before.”
“I recommend this product as much as possible, it met my expectations, you can immediately see the results and feel the dynamics.”
“I poured into the tank because I tanked up this EU siphon with E10 instead of E5 as always. On E10 after a few km.lit up 'check engine'. I immediately guessed that it was about this 'fuel' E10 which is a mess the world has not seen. I purchased Tec2000, poured it in, and after a few km. the 'check engine' message disappeared.”
“I used in a BMW E38 m62b44 I poured a smaller amount of fuel than recommended by the manufacturer, normalized the corrections of the car I drive normally in city mode quietly I did not feel a difference in power but for this corrections in the norm is for the plus.”
“I have been using for many years, previously the version for the 1.5 CRDi diesel engine, now for the 0.9 TCE 90 hp turbocharged gasoline engine and zero problems, neither the diesel nor the current gasoline has ever refused to serve. Both engines on TEC-2000 fired up in the worst cold weather, even despite not the latest batteries. I use twice a year, before winter in November/December for a full tank of fuel I pour one can and the same in the spring around May/June. I recommend!”
“I don't know if it gives anything, but so far it hasn't hurt. I've bought it several times and refill it in different cars, just as a preventive measure, because I drive on LPG. I haven't noticed a difference in engine performance.”
“Fura sometimes (when there were fluctuations in temperature outside, autumn, winter/spring) did not want to start, you spin and nothing, as if the pump does not give fuel. After pouring the specific, the car burns to the touch. The preparation is worth pouring every few months because I had problems with firing up in autumn and then in late winter. The first time I used it, I thought it was a coincidence that the car started normally again, but now, when I used it again after a few months, when the problem occurred again, I have no doubt that the product is effective. Scenic 1.6 2005.”
“Recommended. I applied this additive to dacia duster 1.2 turbo (2016) gasoline. I poured 23l of fuel + additive 375ml. I drove 294km in the city cycle. After conversion, it came out 7.82l/100km. Currently I am in the process of the same 'test' only without the fuel additive, also city cycle.”
“I pour once a year for 1/3 of the fuel in the tank. Everything is ok.”
“It's hard to judge, it seems to have helped but it could be a suggestion, the radical wow is not there in the older Opel Astra car more seems to be an improvement than in the newer Mazda Cx5.”
“It works. I drive little, in my car often occurred ignition loss, I suspected water in the fuel. After applying the additive, the problem disappeared.”
TEC 2000 Fuel System Cleaner
How the gasoline additive works

Cleans and maintains the entire fuel system

Fully removes water and moisture throughout the fuel system

Neutralizes the negative effects of E10 fuel on the fuel and injection system, counteracting the collection of moisture by ethanol, protects the system from corrosion and deposits and the injectors from clogging and damage

Precisely and thoroughly cleans the injectors, corrects the atomization of the injected fuel, maximizes the efficiency of the burned fuel and improves the cold and hot engine starting performance

Expensively reduces harmful exhaust emissions, improves idling culture

Prevents sedimentation and algae growth in the fuel tank

Removes contaminants and protects the top of the cylinders

Perfectly cleans and keeps PCV and EGR valve clean for a longer period of time

Cleans Lambda probe sensor and catalytic converter
Why should you use the TEC 2000 Fuel System Cleaner?
TEC 2000 Fuel System Cleaner is more than just a regular fuel additive – it’s engine protection, better power, and lower fuel consumption all in one. The product effectively binds moisture and removes water from the entire fuel system, drying out the lines, filter, tank, and the fuel supply system.
Tests confirm:
✅ A reduction in exhaust emissions by up to 60%
✅ An increase in engine power by up to 10%
✅ Fuel savings of 4% to 8%, with even better results when used in combination with TEC 2000 Engine Flush.
These are real benefits you’ll feel while driving – smoother acceleration, lower consumption, and better vehicle dynamics.
Innovative FSC fuel additive technology – protecting your engine
The TEC 2000 Fuel System Cleaner effectively removes water from gasoline, protecting the engine from harmful moisture. The presence of water in the fuel system can cause phase separation, or fuel stratification, which negatively affects engine power, stability, and can even prevent it from starting.
The product:
- Cleans the cylinder head and valves from carbon deposits,
- Protects injectors from clogging and ensures full flow,
- Cleans the lambda sensor, allowing for more precise air-fuel mixture dosing,
Reduces deposits on the catalyst, eliminating the unpleasant "rotten egg" exhaust smell.
Additionally, the product works effectively in carburetor engines, unblocking the float from deposits that build up during inactivity – ideal for lawnmowers, agricultural machines, and seasonal vehicles.
Use TEC 2000 Fuel System Cleaner regularly – twice a year – to keep your engine clean, dynamic, and fuel-efficient without the need for costly visits to the mechanic.
TEC 2000 Fuel System Cleaner
How to use
TEC 2000 Fuel System Cleaner is designed for all gasoline engines and is safe for catalytic converters, so you can use it with confidence in your vehicle. The usage is extremely simple – just pour the contents of the can directly into the full fuel tank and start driving, allowing the product to begin cleaning and protecting the fuel system right away.
For best results, it is recommended to repeat the process twice a year – preferably in spring and fall, when temperature fluctuations are greatest and most moisture accumulates in 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.
