What is the primary function of an oil tank in the lubrication system?

Explanation:
The oil tank’s main job is to act as the reservoir for the lubrication system. It holds the system’s oil supply so the pump can draw from a ready source, and it provides enough volume to cover normal demand and to accommodate oil expansion as it heats. Keeping a dedicated space for the oil also helps air separation and lets heavier contaminants settle before the oil is pumped back into the system. It’s not where filtering or circulating happens—that’s done by filters and the pump with the rest of the plumbing.
