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.
- Better engine performance
- Lower fuel consumption
- Lower pollutant emissions
- Protection against corrosion and carburetor icing

Liqui Moly products work!! I have a 2014 Ford Expedition that kept missing in the mornings until the engine warmed up. I had a friend run test with his computer and it showed a miss on the #8 cylinder. I replaced the spark plug, coil pack and fuel injector on cylinder #8. The miss did not clear up. I used two cans of the Liqui Moly Valve cleaner with the Liqui Moly Fuel System Clean out at the same time with a full tank of gas. I did not run the vehicle after I put the valve and the fuel clean-out additives for 8 hours. I did this treatment two times using two full tanks of gas. After some aggressive engine use on the highway, just after the second treatment was added in, the check engine warning light when off and the engine and has stayed off, no more engine missing too. I plan to use this treatment on my engine again every 6 months.

This product really works great.. i have hyundai sonata 2011 2.4l GDI it was little slugish before i put valve cleaner .after putting in almost full tank it showed what it is …increased power and mileage.it used to hesitate/jerk while idling and tried several injecter cleaners which was waste of money.this is the first time i used liqui moly valve cleaner and i am the fan now..would buy other stuffs too from liqui moly…

I didn’t want to remove my valves so I used this to soak them in the head. Worked pretty well.

I find that helps with general engine performance and have added it every few thousand miles.
