Very good product for your car
Have been using it in VW 1.0 TSI Engine which is a direct injection turbocharged engine. Results are satisfactory. The rides are smooth, engine less noisy, less vibratory and starting is pretty quick. My car is E10 complaint but using this with E20 fuel — and there is no drop in mileage or power. Highly recommend, for all petrol engines. Consider it as a multivitamin good supplement for your car.

Satisfied
Working well with my car, though car manufacturers says it's a E20 compatible car but still I used this additive, just to be on safer side. Can't say about the internal rust prevention in fuel line but engine noise reduced a bit and engine smoothness felt while running the car

Genuinely good!
First time user. I had to run a 350-400km trip and I added 2ml of this per litre in my Tata Altroz. The average I got would be at least 2.5 kms more per every litre I used. Saved approx 500rupees in my trip. I also felt less pressure on engine, performance was good while driving on hill terrains and car was performing well also with AC running full time. Genuinely good product.

It does work but give it time and clock some kilometers.
Amazing product! I have used about half a bottle over the last month on my 2022 CB300R (E10). Lately I had been feeling that the bike felt a little choked and was vibrating more than it used to. I started using this on one of the long rides, for the first 100km, I totally forgot that something had been added and I kept pushing on with 20kg of so of additional saddle-weight. It was the second day, after having covered close to 500km that I noticed the difference, on hard acceleration from low revs had about 70% less vibrations, the cruising speed of 100km/h started to feel unstressed, and I could perceive a noticeable difference in acceleration rate without my saddle. Might be placebo, but I'd highly recommend this as at least an yearly exercise.

Good product...but use it with caution
Usefull product, enhances engine smoothness and improves mileage, but never use it with very low fuel level....always fill fuel immediately after adding this product...

Okiesh product
My car has clocked around 19,000kms since 5 years. I bought this as a fuel additive for E20 but haven't seen much effect used only for approx 1000kms. Since the car is less driven the effect of this might not be significant. But there is no increase in average or fuel economy it's the same with or without this additive. But definitely noticed some performance and engine feels smoother and quieter after the use.

Game changer for older engines (BS4)
I was skeptical, so I tested this additive first in my 5 yr old TVS Jupiter. I noticed smoother idling, quicker throttle response, and better mileage. Then I used it in my 2017 Ford EcoSport and 2016 VW Polo both felt noticeably peppier, with reduced engine noise and cleaner exhaust, smoother rides No more vibration during acceleration in traffic. Will definitely use every 3-4 months to keep injectors clean and engines running smooth. Highly recommended !
