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.
