Gumout 510013W-6PK Fuel System Cleaner, 6 Pack

Bought a 6pk to save some $$, was buying at local WM. I add a bottle to vehicles every 3 months, noticed a difference on the high milage vehicle with fuel economy & smoothed out idle .

Been using this product for years in multiple vehicles and it works as advertised- 3 cars are over 100,000 miles and no issues- 1 car over 250,000 miles - purrs like a kitten- proof of performance is when the vehicle reaches high miles and runs perfect

Super awesome product Tacoma has almost 300.000 miles on it and this stuff cleans fuel system better than any professional fuel injection service I’ve had two done on it prior Highly recommended

My vehicle says use Premium Fuel. At $$1.00 a gallon over Regular cost gas, I add a bottle every fill up which saves me $15 every REGULAR fill up. After nearly a year of use, no problems detected ,,,

Not just vest injector cleaner for the money but best one overall in my opinion. No matter what vehicle I put this in I get a performance boost and a considerable one. Usually that implies injectors are indeed getting clogged and most vehicles you can say that is true but no matter what the degree of holdback from your fuel system or injectors this stuff will always give you a boost because it changes the viscosity of the fluid and if you have a performance vehicle or a tune that is allowing more air or even cold air then you're going to want this in every tank to get the most out of your vehicle and because of what I just said is exactly why your fuel efficiency will be better as well. In my Honda when I have the AC on my performance drops so bad it's ridiculous and when I use this I get a lot of that performance back. There's no reason why you shouldn't be able to use this in every tank but realistically you probably only need it every oil change.

Works great to help smooth out a rough running vehicle from either bad gas or gum build up in the fuel system.

I was greatly surprised and impressed by the difference in my car’s performance after two bottles in my gas tank The mileage improved and the engine ran smoother.

I add one bottle monthly to clear fuel injector. been doing that system for 30 years haven’t needed a shop injector clean on any of my 3 vehicles.

Looks like a great product, but I have not used it as yet.

تم تجربته في سيارتي وهذي تجربتي على ربع تانكي بنزين وبعد خمسة أيام تقريباً حسيت بالفرق العزم والصرفيه ، أنصح فيه

I used on Nissan sunny 2016 model GCC car, but there is no difference
