In what applications is it best to use grease over oil?

Using grease over oil is particularly advantageous in applications where oil doesn't stay in place. Grease has a thicker consistency, which allows it to adhere to surfaces more effectively than oil, especially in situations where slippage or drainage is a concern. In environments where equipment may experience vibrations or dynamic movements, grease will remain in place better than oil, reducing the risk of lubrication loss and maintaining a protective film on the components.

In contrast, oil tends to flow more easily and can seep out of joints and components, especially under high speeds or centrifugal forces, making it less effective in maintaining a consistent lubrication presence. This property of grease is particularly beneficial in preventing wear and corrosion in machinery where maintaining a stable lubricant layer is crucial. Other options focus on specific scenarios where using oil might be more suitable, such as high-speed applications or those needing constant lubrication, but they don't address the critical advantage of grease in retention and stability.
