Gumout 510016 ALL-IN-ONE Complete Fuel System Cleaner, 10oz.

Best gas treatment I've found

I have been Professionally repairing vehicles for 48 years. Amazon Gets to Me Fast. Really am Satisfied with Gumout 510016 All-in-ONE Complete Fuel System Cleaner, 10oz. (Pack of 6)

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

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.

works

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 saw this used in a video upload from a reputable mechanic, and I tried it on my 2015 Ram 1500 3.6L per the directions. I noticed an improvement right away in acceleration. I have 83k plus mileage on my truck and have taken care of it but I can honestly say I "felt" the difference. I only use regular unleaded. I poured a bottle nearing empty in tank and added about 18 gallons of gasoline to mix with. I do mostly highway driving so it was able to mix thoroughly inside. Once I was near empty again (so they say to rid most of the contaminates), I filled up the tank. And just check for yourself. Some vehicles may require another bottle but I don't know how often that should be. Hope this gives you an insight on my experience with the product.

I couldn't buy it on Amazon because it was out of stock for a while. But this time, it was on sale again and I bought it. It is very expensive in here so I always like to buy directly from the Amazon.Anyway, I'm using GDI ICE, I always use Gumout every 5,000km. I'm not an car engineer, so I don't know exactly, but while driving my car for about 70K km, I haven't had any problems with the engine or fault codes, and the engine sound hasn't changed much from the beginning. I hope my engin holds up well.
