Liqui Moly (2001-12PK) Valve Clean - 150 ml, (Pack of 12)

I decided to try LIQUI MOLY Valve Clean to help keep the intake valves clean and maintain engine performance, and I’m really impressed with the results. After adding it to the fuel tank and running through a full tank of gas, the engine felt noticeably smoother and more responsive. It’s very easy to use—just pour it into the fuel tank as directed. I also like that it’s from LIQUI MOLY, a brand known for high-quality automotive additives. While it’s not a miracle fix for serious mechanical issues, it’s a great preventative maintenance product to help reduce deposits and keep the engine running efficiently. I plan to use it periodically as part of my regular maintenance routine.

Very good product, works great.

Definitely not a cure-all for major mechanical problems, but it works well as a preventative step. It helps lessen deposits and keeps the engine running smoothly. I intend to use it regularly as part of my maintenance schedule to keep everything in good shape.

Improved my engine

Just had valves cleaned by walnut blasting, going to use this periodically to prevent future buildup. Expecting a lot, since it is such a high-quality brand from Germany.

This stuff is always good. Great company that makes great auto engine products. In my case I have 2 BMW that are direct injection and tend to carbon up the valves. Lots of products out there that are supposed to clean the valves of carbon, but this stuff seems to actually work. The pros say it is one of hte best options outside of removing the engine intake manifold and doing a walnut shell blast of the exposed valves and no one really has time for all that. Buy this stuff and use it regularly

Nothing crazy changing, but it did idle smoother and seems to have a slight bit more power, I also used the catalytic converter cleaner which seemed to actually make an audible’s difference in my exhaust

280k on my 4 cylinder Ranger with leaky valves, causing misfire when shifting. This is much quicker and cheaper and good enough way to go than a complete head rebuild.

Cleans in take valves on direct injection engines.

This valve clean product is very good....and genuine.....turbo gasoline with direct injection has tendency to deposite carbon over valves....so this product use with regular 20-30k kilometres pr serves engine power....seller sent me very genuine product in good packaging
