Good for routine engine care
Size: 150 ml, Pack of 1
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.

Easy valve cleaning for the engine

Just tried the LIQUI MOLY Valve Clean in my car. added it to my fuel, and it seems to help keep things running smoothly. it's handy to have on hand for maintenance, especially when I want to avoid engine issues. it works well in my daily drive and is pretty simple to use. glad i picked this up.
