Easy valve cleaning for the engine
Size: 150 ml, Pack of 1
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.
