How to read this figure
- Oil pan and pickup. The oil rests in the pan on the bench. The pickup line draws it from the pan to the pump.
- Oil pump. Driven by the engine, the pump sends the oil under pressure to the filter head.
- SYNTRAX™ full-flow spin-on. All the oil crosses the pleated SYNTRAX™ element, drawn in section. The larger dots are wear particles and the finer ones soot; moving the cursor sideways changes how much the oil carries, and the readout shows the filter's load.
- Main gallery and bearing feeds. From the filter the oil reaches the main gallery, which distributes it to the bearings through the feeds.
- Return. After lubricating, the oil drains back to the pan through the return line and the circuit starts again.
- Service. Moving the cursor to the top, or pressing E, runs the service: the spin-on is replaced and the new one goes on clean. Head, pump and gallery stay on the engine.
