| **Oil volume to the motor is dependent on pump capabilities and RPM**. When an engine is operated at higher speeds; the volume of oil circulated through the oiling system increases, resulting in higher oil pressure throughout the feed path. As engine speed is reduced, the volume of oil pumped is also reduced, resulting in lower oil pressure throughout the feed path. \\ | **Oil volume to the motor is dependent on pump capabilities and RPM**.
