Valve cleaner. Excellent
It works great but you need to do it 3 times to get great results.

If you want to pick up some ET…
Put this in the original 2JZGTE out of my 1994 Civic EX. Really made the super charger come alive. Want to say I picked up at least 12lbs of boost with the additive. Laid down a solid 15.4 ET and got kicked off the track first time out. Nuff said.

Cleaning in a bottle, no fuzz!
This is the only product you'll ever need for your injector and chamber cleaning. My MBZ gets it every 6 months, and it ensures like a rabbit. Try it. Value for money: Compared to the auto parts 5 dollar option, this one delivers Works well: No hesitation, immediate response and feedback at acceleration Cleaning ability: Keeps your engine running at perfect idle, only needs it 2X per year, priceless!!

Reputable, reasonably priced fuel additive to clean valves, with handy dispenser. Not all comes out.
Honest review of Liqui Moly 2001 Valve Clean - 150 ml , blue @ $7.49 at time of order. I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some valve cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work. Likes: Amazon Prime shipping, returns and refunds within 30 days of receipt. Reputable product. The price point seemed reasonable, especially if it works as advertised (5.0 ounces, single treatment can). Comes with dispensing attachment for easier pouring into the tank. Dislikes: The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside. Meh: I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps. Hopefully this honest review helps someone decide about this product.

Better than other gas additives.
Used half a can on a tank of gas for my motorcycle. Within 50 miles I noticed a quieter engine and a significant power increase. Definitely recommend.

Good stuff for old vehicles sitting around
I typically use seafoam as my fuel injector cleaner and could tell a slight difference when I used it on a car I had left sitting for awhile, when I put this liquimoly in I noticed a major difference. Idling went back to normal by the end of the tank. I tried this on a whim because it was on sale for 2 bottles, I'm very glad I did. I'll be using this stuff from now on.

Works! Especially with other Liqui Moly Products
I have been using Liqui Moly Products for years in my Volkswagens and Audis. I used the valve clean product and injector cleaner product in my wife’s 2019 Jeep JL before going on a 500 mile drive to Pennsylvania. I wanted to test this product out to get an idea of how much our gas mileage changed. Using this valve clean and the injector cleaner product I saw almost a 2 mile per gallon increase over the trip. Additionally, since the trip, gas mileage has been on average at least one mile per gallon better than usual, the Jeep accelerates better and smoother. this is a great value for money and is very easy to use. My suggestion would be to use this product on every fourth fill up and the injector cleaner product maybe three times a year to keep buildup down especially in the jeep JL.

منتج رائع يساعد على تنظيف الصمامات وتحسين أداء المحرك بشكل ملحوظ. بعد استخدامه لاحظت سلاسة أكبر في التسارع وانخفاض بسيط في استهلاك الوقود. سهل الاستخدام ونتيجته فعّالة جدًا
