Gumout 510016 All-in-ONE Complete Fuel System Cleaner, 10oz. (Pack of 6)

It’s caused my vehicle to run much better

Would Buy Again.

This is some of the best fuel injector cleaner out there. One of the highest concentrations of P.E.A. of the Gumout Regane line of products, and treats up to 35 gallons of fuel, so for many vehicles, this one bottle is 2 treatments. I use it every oil change (pour a bottle in about 500 miles before oil change time). I have read it is best to do it prior to an oil change since there is the small possibility of fuel/cleaner getting mixed with engine oil and possibly causing issues. I personally think it is bunk, but it is an easy time to remember to add if I do it before the oil change. The directions say add to an almost empty tank then fill tank and drive till almost empty, but I just add it whenever and top the tank off, then drive till empty. No this will not make your vehicle get double its normal gas mileage, it will not fix mechanical problems. One bottle will not magically clean up years of buildup and gunk, but used regularly it will clean carbon build-up in the combustion chamber and clean out the fuel line and injectors of any build up.

I put these in every 3,000 miles and every time you can feel the difference in the response of the car. I'm assuming that means it's doing its job. Just like a new oil change I would compare it to. I wonder how it would feel if I did them at the same time. They tell you to but it must feel like a brand new car just off the lot with only 20 miles on the dash.

Among all the you tube videos on gas additives, this one delivers.

2017 WRX loves this stuff :) matched with a GDI service (intake/exhaust valves with Gumout's Valve cleaner, TGV + EGR). 60k miles and running like the day I bought her at 0 miles <3

ممتاز جدا يساعد على استخراج الكربون من السيارة، ولكن أنصح باستخدامه على الخطوط الطويلة، وأيضا، عدم ترك. خزان الوقود أكثر من 3 أيام مع المنتج، يجب عليك أن تمسك خط لكي تستخلص فائدة المنتج

وضعت كامل العبوة على تانكي سيارتي 60 لتر بتركيز عالي ( الموصى علبة كاملة تعالج 95 لتر ) النتائج ظهرت على نهاية خزان الوقود المحرك صار انعم بشيء بسيط استجابة دواسة البنزين افضل تحسن طفيف بصرفية الوقود على العموم المنتج رائع لكنه ليس بسحر افضل استعمال له علبة كل 10 الاف كيلو او مع كل تغير زيت يظهر فوائدة على المدى البعيد او الاستعمال المتكرر

Nothing happened

fantastic stuff

Smooth driving and fuel consumption is better than before
