On an old and for years unmaintained 2003 Hyundai Getz, a bottle of Flamingo Octane Booster Gasoline Additive 250ml combined with Flamingo Gasoline Cleaner Additive 250ml, BEFORE filling up with 100-octane gasoline, managed to turn off the permanently lit Check Engine light after 1 day and gave the first signs of revival to the choked little Getz.
On the 2nd fill-up, again in the same way and combination, there was incredible response on the pedal and a combination of nerve and torque that the car had never seen before!

P.S. I also got the rest of Flamingo's products [Coolant Additive, Oil Treatment, and Oil Smoke Reducer] and I have truly seen excellent results! VFM and 5* in everything!

In an Alfa Romeo 147 the product is a joke.
The injectors knock more than before.
I have tried another product, more expensive indeed but with amazing performance for four full tanks, the car didn't make a sound even uphill.
This one belongs in the trash bin.
Stay away.

Excellent! It revived an old 125cc scooter. I was reading reviews saying that boosters do almost nothing for their cars and I was disappointed. I saw this one, which is very cheap, and got one to try along with the company's cleaner. Of course, I always used premium fuel to give a little extra boost, but as soon as I added the booster and cleaner, I noticed a tremendous difference. Much better torque and acceleration, and I gained a little in top speed. The engine runs much more steadily and smoothly, especially at high revs. Of course, I didn't measure it well and added about 1/3 to a 6-liter tank, but it doesn't matter, it's cheap, and I've ordered more

In a turbo car with a program, I noticed a difference; it has become more responsive, specifically a Passat 1.8 20vt, it's worth trying!

Well, on the Benelli TRK 702X 2024 model, for Athens-Thessaloniki (Peraia)!

Classic consumption 4.6-4.8 per 100 km with an average speed of 110-125 km, the reserve light comes on at 330 and comfortably takes me up to 380 + boldly.
*With a 20-liter tank, I put in half a bottle and a little more.
Result: consumption 5.3 - 5.5 with 110-125 km on the highway, reserve light at 310. (After I filled up, I saw that it had another 2.5 liters left, so it barely would have made it to 340 at best!
Final conclusion: I won't buy it again; it didn't offer me better consumption nor any difference in terms of engine life because it's a perfectly maintained 9-month-old machine.
My opinion!

I remembered how my car was new. Terrible improvement. If you repeat it with every fill-up for at least three times, you have a different car; combined with the cleaner from the same line, the car literally flies.

I put the bottle in 60 liters of gasoline. I did not see any improvement in performance or reduction in consumption. The noise from the injectors was eliminated.

In combination with the same company's cleaner, my Lambda sensor light went off, well done I didn't expect it

Created a problem in the carburetor of the 125 motorcycle. Inappropriate combustion and operation. There was no improvement

I poured the entire bottle into 30 liters of gasoline, but I didn't see any difference. I reserve judgment on the product, because the reason I used it was poor quality gasoline resulting in engine knocking. It didn't help, but perhaps the gasoline was so bad that nothing could save it.

It gives an extra 5% power compared to a regular 95 octane fuel! It's not something crazy, but on my 125cc scooter it means that I can climb uphill with an additional 3 km/h and not bother the "impatient" drivers behind me. I use it constantly and I am satisfied.

Quite good for its money. It does what it promises and you can feel the difference even in a semi-spherical engine.

In the Fiat Panda Mild Hybrid 2023, the engine revs much faster, reaching the red line on the tachometer 2 seconds earlier. There is a significant difference in trips, with greater ease in overtaking and gaining several meters due to the increased acceleration in a shorter unit of time.
The car reacts more flexibly than with expensive 100-octane gasoline.
Certainly, on long-distance trips on the highway, you will notice a difference in the gas pedal, but now in the city, waiting at the traffic light and using the start-stop function, I don't think you will notice a difference.
So, for everyday use, it's not that necessary.

Excellent product, I tried it on my motorcycle and also on my car (Honda HR-V 1600) - (Yamaha XTR 660) and it really gave them life, which I didn't expect since I thought they wouldn't do anything. It really deserves its money because it does the job. Now I put it in every two fillings and I see the difference

I put 1/3 in the vstrom, in about 18 liters of gasoline, and the engine ran smoothly, starting up easily in the morning.

Tested on a 2005 Toyota Corolla 1.4 VVTi. The car runs on both gasoline and gas. On gasoline, the car had a slight tremor at idle. As soon as I added the injector cleaner + octane booster (to a full tank) I noticed that the tremor disappeared after a few days. My mechanic told me that these specific products from Flamingo don't work on gasoline. Personally, it did the job for me, but we'll see later if it presents any issues.

The product was used in a 2008 Chevrolet Matiz model with a 0.8L version.
By its nature, it has a "nervous" throttle.
It gives an extra "click" to the car's engine.
Value for money, honest!!

I used it together with the corresponding cleaner from the same company! The difference was immediate and intense, I must say! I feel like the car is listening or has become much lighter on the gas, and there is even a noticeable difference in fuel economy. This is the second time I have used them... very satisfied!

I used 5 bottles... 5 tanks... I didn't see any difference... only in consumption, it increased from 8 liters/100 to 10 liters/100

Very good product.
You feel a noticeable difference in performance.
Okay, it doesn't work miracles, don't go crazy! But I think it's worth its money

I put it on and filled it with 98 octane fuel (every Friday and Saturday a company offers a 4-minute bonus, 2 euros for 50 liters) and I noticed a difference in performance and consumption. Of course, this is in turbo. I imagine it will also do the job in naturally aspirated.

Very good, you feel the gas softer when stepping on it, now for power you should have put a 100 or reinforced to see it, otherwise very few things. But good.

I got it for testing at first and I liked it...!!! I put it in a 1997 Renault Twingo 1.200cc... with 95 octane gasoline and I really see a noticeable difference...!!!
Then I ordered 6-7 pieces and since I only do refills, I use it once every 3 refills... I just hope the "little bucket" doesn't get damaged...!!!

I think it runs smoother.. the sound of the machine in the Smart is in our ears, that's why I know that now the sound is softer.. but only until there

I don't know if it cleaned anything, what I know is that with this inside the fuel consumption increases at least 10% !!

Usually in my car, I can tell the difference between 95 and 100 octane gasoline.
With this specific additive, I didn't notice any difference. Next time, I will try a different one.

I can say that it boosts octane levels.
I use it with 98 gasoline.
And I haven't had any issues.
I only have issues with 98 gasoline.
The only thing I don't like about the product
is that it says to be used every 3000 kilometers for better results

Tested on a 650cc engine, it did the job.... The bike started much faster and I noticed a slight improvement in low RPMs as well as a small difference in fuel consumption, about 0.5 l/100. A very good product with an excellent price

It did what it said. The car stopped stuttering obviously due to poor quality gasoline. It was used in combination with the fuel cleaner of the same company.
