Your cart is empty.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.

I add it to my 2001 Mercedes C320 on every fill up. The engine runs noticeably smoother and feels more powerful. The effect is not noticeable in newer cars (Porsche 911 and Lexus RX350).

I have a 1992 ford mustang 5.0 with 50,000 miles. You have to use half the case (6) to see results. I noticed my Stang fires up better, actually it roars now when I start it up and purrs when I cruise at low speed. It's an awesome sound that needs to be witnessed. I found this product on YouTube on Nate's video of intake valve cleaning. I absolutely DO NOT, and I mean DO NOT advice you spraying it into the intake unless you know what you're doing and dealing with, and I DO NOT recommend it to people at all unless you are a mechanic preferably certified because of the fire hazard and destroying your engine, otherwise, just follow protocol and put it in your gas tank. It really works. Most gas treatments are over priced these days including this brand but I really know how bad carbon is in an engine being a self taught chemist and mechanic. Carbon destroys your engine, gas mileage, thus, your power. The price will deter me from using it continually but I may use it in the future, perhaps. Thank you Liqui Moly for your fantastic product! It is not snake oil.

This is a great value for the price and the amount you get, use it on my direct injection thru the vacuum to maintain valves clean. Please note that if the valves are already too dirty this won’t clean them, it’s meant to maintain them clean

The valve cleaning effect is structurally absent in GDi engine vehicles. However, it burns better and delays carbon deposition during recycling. Other than that, cleaning where the fuel goes is the basis of fuel additives.

I have a 1997 Toyota Corolla with 240,000 miles. I’m hoping it helps.
