STP 200559J Diesel Fuel Treatment and Injector Cleaner (236 ml)

I used this on my 2017 Vento TDi which has done 23k kms. I added this to my tank after filling up 40L of fuel.My observations are as follows :- The effects were noticeable only after driving about 150 KMs.- The engine sure had become smoother than before.- The car accelerated with less resistance thus giving an impression of increased pick-up. "It pulls cleaner" is what struck my mind while experiencing the change.- Idle sound after engine warm-up decreased noticeably.- Engine sound while driving under normal acceleration or at constant speeds, had come down by a huge level. There was barely any engine sound when not accelerating.- No black smoke in rear view mirror under hard acceleration. (It was present before using the additive)- Knocking sound in lower gears in low speeds decreased.- Didn't check mileage, so can't comment about the same.Conclusion : Worth the purchase. Gives a smooth drive and pulls cleaner. When driven sedately, the sound of engine is barely audible.

I used this product in my Skoda Laura Automatic 2013 model, and I see the result is very good, Engine noise has come to very minimum level i.e. you have to feel by putting your hands on the bonet whether car is in start condition. Regarding mileage, i didn't notice any increase in km. But I feel very happy while driving, very smooth driving, I suggest you should use this product once, no harm to engine..... thanks

I have used this product in the past and was happy with the results but this time I used this at 85k kms. I was preparing a long journey of 450kms in a single stretch. Filled up my tank so total diesel in tak was 45 litres and used 1 bottle of this Fuel Treatment and I was able to notice the difference just after 20-30 kms. I covered the same journey 10 days ago and my engine RPM's were reaching 2500-3000 between 130-140 KMPH and Mileage was 19 but this time there was a drop in RPM and mileage was 20. Same speeds can be achieved with 2000-2500 RPM. I also noticed a improvement in pickup and engine noise.Will definately recommend it.

As per my observation I noticed a slight reduction in engine noise.I used it by adding in full tank 45ltrsMy care is i20 elite asta 2016. Showroom service vehicle.The current km I drove was 85000.The block omissions from engine is still continuing.

Engine Noise: The first and obvious change i noticed was engine noise, pleasantly surprised that i noticed the change within 1 hour of using the productExhaust Smoke. Smoke from exhaust drastically reduced, and this was very evident since this was one of the reasons i had tried the product and it works.Mileage: Didnt see much change in the mileage; a very marginal increase of 0.3, may be it will increase but for now very little change in mileagePickup: ImprovedA great buy, iam satisfied. An easy way cleanse your fuel injectors and improve overall performanceCar i drive is swift diesel, 80000 kms driven. emptied the bottle in in 3/4 tank and the product did 70% of what the company claimed. Go for the product but don't expect drastic change in mileage. Good to reduce engine noise and exhaust smoke

Have added to my Tiago after every 15K of running & after 2 years of running and clocked 89,000,still no black smoke is visible during startup and acceleration also vibration levels during start are bare minimum.My colleague who has similar vehicle but 1 year old & clocked 50K & has not used anything till now except regular oil change and service is facing severe black smoke issues during running and acceleration. So i believe this product really works!!

Poured half the bottle in a 25 litre diesel.10 litre diesel in tank, poured half the bottle and fill up 15 litres. (As the full bottle is designed for 50 litres)After driving, 10+ km, the engine is super smooth, there is no lag in power delivery, it's kicking like anything... Drove over 100 km as of now, the mileage is increased from 16 to 21km/l, the avg speed is 100-110km/hr.Model : Honda Amaze IDTEC (ODO Reading : 15k KM)Will use next half at 20k ODO. I suggest to use one full bottle for 10k kms with intervals of 5k km.

The milage of my car has gone down by a 1 - 1.5 km/l after putting this in a full tank of my i20 2014 diesel model.I am writing this review after 9 months of using this solution. I thought that the car might come back to its initial level after sometime but it has not happened till now, so not hoping it anymore now.
