Noticeable Improvement in Engine Smoothness
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.

Great at keeping carbon build up off the valves on a direct fuel injection engine
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

Hopefully a great preventative measure
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.

Good product recommend other ones too
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

Performance improvement
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.
