👉 The hub fluid, also known as grease or lubricating oil, is a critical component in the operation of internal combustion engines, particularly those with oil pumps. It serves to reduce friction between moving parts within the engine's housing, especially at high speeds and under heavy loads. This fluid also helps to dissipate heat generated by the engine, preventing overheating and ensuring smooth operation. By maintaining a thin layer of lubrication, the hub fluid extends the engine's lifespan and improves its efficiency.
