“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.”
