Which type of lubricating oil method is LEAST likely to have a lube oil strainer or filter?

Correct Answer: Option B — Static-feed

Static-feed lubrication relies solely on gravity or capillary action from a reservoir without mechanical pumping or forced circulation. Because there is no active flow loop or pressure differential to drive oil through a filter element, these systems typically lack integrated strainers, unlike pressure, force, or gravity-feed systems.
