Why is grease useful when lubricant dripping or splattering must be limited?

Grease is a solid or semisolid lubricant composed of a thickening agent—such as soap or inorganic gels—dispersed within a liquid lubricant.12

It is particularly useful in applications where dripping or splattering must be limited because its semisolid consistency allows it to remain in place more effectively than liquid oils. Beyond preventing leakage, grease is preferred when less frequent application is required, when the lubricant must act as a seal against contaminants, or when the system requires less sensitivity to inaccuracies in mating parts.2
