How Does Car Engine Oil Work?

Modern engine oil. Incredible engineering that enables incredible performance.


By lubricating the engine, the oil isn’t simply keeping it running smoothly, it’s protecting it and preventing damage.


Oil begins its journey in the engine’s sump – a reservoir of oil. From here, it gets pumped around the engine.

The oil pump is vital to the life of the engine. It sucks oil up from the sump through a pickup tube, pressurises it, and sends it around the entire

engine through a circuit of oil ways.


From the pump, the oil travels to the oil filter, which removes microscopic particles and supplies clean oil to the rest of the engine.


Clean oil flows to all the critical engine parts…

The bearings – supporting the crankshaft on a continuous film of oil…

Pistons – cooled down and kept clean by the oil’s detergent action…

And the valve train, protected by the oils anti-wear system.

Loads in the valve train are the highest in the engine, this is where the oil experiences the most stress.


To avoid friction and damaging wear, these fast-moving, metal components

must be lubricated.


The oil is the only thing preventing metal-to-metal contact.


Returning to the sump via oil return channels, the oil completes its journey.


This whole journey can take as little as seconds!


Throughout the oil’s journey, its primary function is to protect.

It does this in many ways


Reducing friction and metal to metal contact


Reducing wear throughout the drive


And reducing harmful deposits


Regular maintenance with a quality oil and filter will protect and

preserve the heart of the car – the engine – keeping it running at its best,

for longer.


It’s more than just oil, it’s Liquid Engineering
