Besides fuel, oil is the lifeblood of your vehicle. It keeps your engine rotating smoothly. This is accomplished by the properties of oil that allow it to lubricate moving parts and reduce heat generated by friction. If the moving parts in your engine weren't lubricated, you'd hear a lot of screeching noise followed by a car that doesn't really want to go anywhere. How does it all work? Jason Fenske from Engineering Explained is here to walk us through it all.

The discussion above goes into the nitty gritty related to how oil moves through the engine system. We're talking about parts like pumps, filters, and rails used to shuffle fluids to and from a given space. In an engine, you will see the oil flowing from the oil sump through the pickup tube and on to the crank, pistons, and valves. From there, it falls into the oil pan only to begin the journey again.

It's an intriguing bit of engineering that Jason breaks down. As his channel name implies, he explains the engineering behind all of this. Watch the video and you'll walk away with a greater understanding of how your car works. As a bonus, Jason finishes by explaining some of the advantages of synthetic oil. Of course, he did a full video on that, and you can find out more here.
