I did not notice an improvement in mpg, nor in engine smoothness, but both of those were ok to begin with.I did notice a slight kick in throttle response.I plan to use this every 10K miles.

Last time I used Abro fuel injector cleaner was 10,000 km back. Engine started feeling little sluggish recently, specially the throttle response, the surge while pressing the throttle was less. Well, it was clear indication of clogged injectors, valves with deposits. This time I tried Gumout, first bottle, difference started coming after 50-100 km drive. Poured 1 more bottle with full tank gas, this time it yield really good result. Less gear changes on ghat section, punchy pickup, steady progress @ 5th gear, exceptional mileage (16kpl), everytime I have been to Ooty (from BLR) I got around 12.5 kpl. This time I was really surprised to see the mileage figure. And as per my experience it was due to the ability of maintaining higher gears mostly. Happy to feel that this thing worked. But I used 2 bottles back to back. I generally do that. I never felt one single bottle could clean all the deposits with any cleaner. I wont even hesitate to use in 3 tank fulls back to back. My advice is to use it before a long journey, consistent higher rpms and optimum engine temperature helps to work Cleaner better.

Wait and watch scene...Waiting for the effect to kick in....but got it at half the price so was worth it...Update.....screwed my injector....car started knocking like crazy after abt 600km of usage.....had to get the injector serviced.... costed me 800 bucks...DTIW....Furthur update....after the injector cleaning the knocking sound vanished but came back ... it was a faulty hose pipe and the radiator needed flushing ....the mechanic explained that one of the hose pipes wasnt getting warm.. meaning the coolant wasnt circulating properly thru the engine..now i wonder if the injector needed cleaning in the first place....

Excellent way to clean your Dirty Injectors!I used this on a relatively old engine which has done over 65,000 KM !One-tank mixed with this cleaner later, the car feels much preppier, idling is notably smoother and acceleration is notably quicker. This product definitely perform as advertised.Difference felt was quite good! Engine Responded well to this.Some of the Benefits of using this product - This helps in cleaning the following -Fuel Injector Deposits (FID)Helps Cold engines start easier.Improves Throttle response and acceleration.Reduces Engine Vibration in Idle.Decreases Hydrocarbon and carbon monoxide emissions.I saw 0 improvement in Mileage! This product will work on cars that have dirty injectors, I would recommend this product for ant car that has done over 35,000KM.Do Note - You can not use this product for Diesle/CNG engines. This is meant for only Petrol Engines.You can use this on FI bikes but make sure you measure the required quantity.

Effective. Car would not start last winter due to water in tank, put this in and waited a few hours, fired right up.

I'm not a mechanic so cant say if it is really working. My car and motorcycle are running fine, so it certainly did no harm.

I've used this, but it's hard to say if there's any real impact. Some others have said that they say their car felt difference. I haven't noticed any change in performance, but then everything was good before i started using it. This is inexpensive and I haven't heard anything negative about it. They recommend using it every 3,000 miles. I don't think I'll be doing that but, considering how inexpensive it is I may use it every 9,000-12,0000 miles or so.
