Dry Sump Lubrication

It is used in racing cars and some high-performance road cars. It prevents oil starvation during hard cornering, braking and acceleration. The shallow oil pan lets the engine sit lower in the car. Because the tank can be placed away from the engine, weight distribution can also improve. The system needs more pipes and connections, which must be inspected for leaks.

Scavenge pumps pull oil from the engine to the tank, and a pressure pump feeds it back to the bearings.

The oil level check procedure is different; it is often done with the engine warm and running or via the display. The system holds more oil, so oil changes cost more.
