Don't be confused by the amount inside when you shake the canister. It has exactly as much as needed for a tank up to 45-50lt.
IMPORTANT: make sure the tank is empty and release any remaining pressure inside by pressing the ball of the cap with an object (e.g. screwdriver). This is the only way for the entire canister to go in. Now, whether it actually works is another matter. It certainly doesn't do any harm or damage though.

It did absolutely nothing for me, I think the interruptions and hesitation increased in gas that was working fine, fortunately it returned to normal after a few refuels

Quite a good product, it really gave life to the car's engine. Before I used it, the LPG system would frequently switch: as soon as I turned it on and after a few kilometers, it would switch on its own from gas to petrol.

Since I started using it, everything changed. The car runs properly on gas, without unexpected fuel changes and with noticeably less rattling.

I believe that for those who have an LPG car, it is almost essential to use it, especially if they are facing issues with the system's operation

It must be good, I have no idea, I have used it 2-3 times a year out of principle, I haven't had any problem with the gas. That's why I will continue to buy it

The engine immediately stopped cutting out when running on LPG... I don't know if it's an LPG issue that they're selling us and with the additive the mixture essentially became as it should be in proportions... we'll see... I've bought a second bottle as well... I hope it's as described and the minor issues have been resolved... When applying, you need to tighten the adapter very well so that it bends into a U shape to get the whole bottle in...

It improved the performance and some misfires almost disappeared, it seems to me that the car is more lively now and more stable in performance. Good product!!!

Very good product!!! I use it every 5000 km. It cleans the LPG injectors and the whole system. I noticed smoother operation and better fuel consumption. In a car where one injector was knocking, I used it and since then it runs perfectly for many kilometers now!!!!!

I bought two bottles. One was defective and didn't have enough pressure to go into the tank. The other emptied immediately.
One bottle was a waste of money.
And from what I see, it's a common problem for everyone.

1st review 5 stars and concerns the method of insertion. The product requires attention to two points in order to be inserted easily and quickly. First, the insertion nozzle must be screwed on carefully so that it fits exactly, second, once we place the container at the insertion end, we must lift it at a 45-degree angle. In this way, the contents are inserted into the tank in seconds.
The second review in a few days will concern the performance of the cleaner.......

I applied the procedure with an almost empty tank with the engine off and also in operation. The bottle in an upright position. 1/5 was sprayed into the system with difficulty and then there was no pressure in the bottle, resulting in a lot of product being wasted. I bought 3 bottles, used two, and nothing. The use is very simple, it's not rocket science. I probably got a faulty batch. The store claims I did something wrong during use...

It has been used for the last few years in a CITROEN C4 1.6 COUPE with 290,000 kilometers on the odometer, the last 150,000 with LPG. As a precaution, I add one to the LPG tank every 10,000, but also an additive to the gasoline tank with every fill-up. No problems so far!

Very good product. Worth the money.
100% satisfied with fuel economy, thus more kilometers by 10% to 15%

The car experienced interruptions at low RPMs and difficulty starting when using gas. With the use of the cleaner, the problem was minimized.

Very good and at an excellent price.
It helps in the good operation of the nozzle and generally the lpg system.

I didn't see any difference, I didn't have any known issue, I suppose it did what it was supposed to do without me realizing it

Very good product - Easy to use - Immediate improvement in gas combustion & fuel consumption reduction!

Instead of opening the gas at 60 degrees, it opened at 90 degrees. I filled it with an empty tank and somewhere around 300km that I had driven, the problem was fixed. I had never sprayed the car since the installation of the gas.

50-50 literally. I ordered two containers, the first of which I tried to put in a completely empty tank and turned off car, after half of it fell down because it was dripping from the top of the spray and the rest was spitting back as soon as I removed it from the adapter, the other half seemed to have stayed inside the container without much desire to come out. On the other hand, I tried the second container beyond the instructions with an almost full tank and the car running, and as soon as I put the adapter and pressed the nozzle, it emptied within seconds, which simply shows me that the first container was probably defective, a small flaw. If I remember, I will return if and when I see any difference in performance/distance I will make.

In a car with the filling valve on the bumper, the gas enters in 15-20 seconds.
Condition is that the car's tank is empty. Now, as for whether it does the job... time will tell.
In a span of 2 months, I used 3 bottles. With each refill, I noticed a difference of about 20 kilometers. Very good product.

AMAZING PRODUCT. Finally, no more stalling at low speeds. The idle has smoothed out. The entire engine operation has become smooth. Such an inexpensive product is truly miraculous

By far the best thing on the market!! The car revved over 2800 RPM and made maneuvers.. Now it works like a charm!!!

Easy installation in the tank through the car's gas cap, provided that the tank is empty. Now, regarding the protection, unfortunately, it is something that remains to be proven over time. Personally, I trusted a friend who had been using it for years in his own vehicle and had no problems with valves, etc.

I used it once because one nozzle was clogged and I hoped it would help. It didn't help, but that's probably logical. Overall, I didn't see any difference, neither for the better nor for the worse.

Without having any problems with fuel change, I installed it. It seems to do the job... I saw about 50km more with the tank, if it wasn't because of LPG, it would be better quality.

Indeed it did the job, the clog was removed and it no longer leaks. I didn't expect it since additives are usually useless.

I couldn't fit the entire product into my gas tank, even when it was empty, because the hole is located at the bottom of my bumper. The canister doesn't have enough pressure to allow the entire quantity to be inserted into the tank. In a vehicle where the gas filling hole is facing upwards, it works 100%

Quite a good product... It does the job... Those of you who have a serious problem, better to address a repair shop...

I used it twice, with approximately 6,000km between applications. I can say that it had absolutely no impact on anything. Neither the sound changed, nor the fuel consumption improved, nor anything at all.

Very good product, excellent I would say and economical. It has nothing to envy from the famous expensive ones.

With 2 bottles that I added with a difference of 1200 km each, the sound of the car engine changed. It doesn't produce more kilometers. The consumption doesn't change either. But it does work even at idle if it's unstable.
