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.

Our 2004 Durango had issues. The check engine light had been on for many months, and the code indicated an O2 sensor was the issue. But it still ran fine, and since we didn't use it that much, we never replaced the O2 sensor. But then the Durango started running rough. When it first started, it idled rough. When going slow and steady it usually ran ok, but any demand for more fuel, like accelerating or going uphill, and it would miss like crazy. The Durango would also shake and you weren't sure if it would keep running or not. The check engine light would also flash during this time. So we started thinking about where we were going to take it to get it repaired. One day I decided to try a bottle of this Gumout fuel system cleaner. The first couple of trips still had the same missing issues, but then it gradually started to get better. (These were all short trips to the store and back so it took a little longer to work). But then one day the car started up and idled just fine. It accelerated just fine, and the check engine light was out for the first time in months! From then on, the Durango never missed again, and the check engine light never came back on. The old Durango now runs as well as it did when it was new! I don't know how this stuff could even help an O2 sensor, but apparently it did. I have since put a second bottle in the car, and will order another one just to have on hand. This is a great product that really works! In our case, it was a miracle in a bottle!

Used one bottle during a fill-up and noticed slightly smoother engine performance. It’s hard to measure long-term effects, but for the price and quantity, it’s a great value. Easy to use and well-packaged. I’ll continue using it as part of my regular maintenance routine. One star off just because results aren’t dramatic.

I did a little research and found out this product uses PEA as an additive and had good reviews. I tried it in a '16 Camry 2.5 that was starting to develop a bit of rough idle stopped in gear with no accessory load. I put a bottle in at 1/2 tank or 8 gallons, and by the time I got to a 1/4 tank the problem was nearly gone. By the time I got to 1/16 of a tank the problem was gone. I will be using this product at every 5K mile oil change. I am sold! This car is not direct injection so it is cleaning the intake valves as well. Oh and BTW I use top tier gas whenever possible and the car has 150k miles.

I recently tried out the Gumout 510013W-6PK Fuel System Cleaner, and let me tell you, it's a game-changer. My car has been running so much smoother since I started using it. I love how easy it is to use - just pour it in and let it do its thing. The best part is, I've noticed a significant improvement in my fuel efficiency. Plus, the pack of 6 is super convenient to have on hand for regular treatments. I can't recommend this product highly enough. If you want to keep your engine in top shape and get better mileage, this is the way to go. Trust me, you won't be disappointed with the results!

It seems to be helping my car out when it got super slow acceleration. The injectors might have been a little clogged and it's helped.

There just isn't any other carb cleaner as good as this. It has been used for many years and keep the old carb engines working just fine.
