Product Description

Engines are subjected to extreme loads even under normal driving conditions such as town and commuter traffic, short journeys and traffic jams. This sort of use causes the build-up of deposits on valves, in the combustion chamber and in the carburetor. Valve Clean cleans valves, injection systems, intakes, carburetors and combustion chambers and keeps them clean. Clean engines save fuel. Promotes optimum engine performance and fuel utilization. The combustion produces a lower level of pollutants and the engine is spared. Protects against corrosion and carburetor icing. Tried and tested in turbo-chargers and catalytic converters.

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.

Reviewed in the United States on April 28, 2024
Size: 150 MilliliterVerified Purchase
Fill tank and add. Noticed about a 3 to 4 mpg increase about a quarter into the tank. I have a luxury European vehicle and worked fine with no seen side effects. This was the second phase of my fuel cleaning. The first tank was the injector cleaner and this was to clean the valves. My thought was that any stuff from cleaning the injections may foul the valves so cleaned the injectors and then valves. Prices vary so look at the different vendors for the best deal.

5.0 out of 5 stars This one works above all other brands like it
Reviewed in the United States on April 8, 2024
Size: 150 MilliliterVerified Purchase
So we have all seen products that claim to do the same thing but we can never really notice a difference. But this brand and Lucas are the ONLY two I’ve found to do the same thing. This one work much better than Lucas brand does. I can hear and see a noticeable difference and improvement in my Beemers engine. It’s quieter, smoother, better gas mileage, more power and just an overall seemingly happier engine lol. After 3 bottles, and 3 two third tanks of gas. I noticed a difference after the first tank. I was told by the mechanic who did my valve cover gasket that there was a ton of carbon in my n54 beemer. Some products seem like mumbo jumbo but this stuff works so much that i ordered their engine flush product to do next.

4.0 out of 5 stars All n All happy with this product.
Reviewed in the United States on December 7, 2023
Size: 150 MilliliterVerified Purchase
So far have been very pleased with the results. Engine runs a little smoother and a little quieter.
Very hard to remove the cap though. Have to line it up just so....and squeeze really hard while turning.
And then you have to pull to get to the contents. Even if you're careful, you may splash a little on you.
So, make sure you're not wearing anything expensive or fancy when you open it.
And wash your hands well.
Mine actually had some that was dribbled on the outside of the can.
I do plan to buy it again in a few months.
It's the strangest thing though....I've seen the price here on this site go up and down by several dollars within a short period of time.
Huh? wonder why?
Anyway , totally worth it to buy this and use it in your vehicle!
