Question 133General Subjects - 1st Asst/Chief

The correct answer is B) Static-feed. Static-feed lubricating oil systems are the least likely to have a lube oil strainer or filter. In a static-feed system, the lubricating oil is drawn from a reservoir and distributed to the various components by gravity, without the use of a pump. Since there is no active circulation or pressurization of the oil, a strainer or filter is generally not required to protect the system components. In contrast, pressure-feed (A), gravity-feed (C), and force-feed (D) systems typically utilize a strainer or filter to ensure that contaminants are removed from the lubricating oil before it reaches the critical components, as these systems rely on active circulation or pressurization of the oil.
