Revitalizing Fuel System Cleaner for Smooth Driving
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!

This cleaner actually works, many of them don't.
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.

Hands down the best injector cleaner
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.

Solid Product for Routine Maintenance
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.

Worth the try
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

A friend reported significant performance improvement in his 2017 Yaris after just a few miles of adding it to a full tank.
