What are four important jobs performed by a good engine lubricant?

Engine oil is an essential lubricant that keeps the heart of many vehicles and industrial equipment running at maximum performance.

An engine that is operating at optimum capacity can reduce costs for companies and increase revenues, thanks to higher rates of production and less fuel consumption. An effective engine oil can offer these business benefits along with extending the active service life of machinery and vehicles, and reduce how often they require expensive repairs and replacement parts.

To ensure the engine lubricant you select can offer these advantages, read on to discover the four key tasks a product must perform efficiently to be worth its price of purchase.

1. Lubricating

The key role of any effective engine oil is to lubricate. As engines work, the metal surfaces of their moving parts come into contact. Without appropriate lubrication, these metal components will grind against each other causing damage from friction and wear. With parts unable to move freely, engine performance levels are also impacted. A high-quality engine lubricant will keep a steady stream of oil flowing through mechanical system ensuring all components are appropriately coated.

2. Cooling

In an internal combustion engine (ICE), heat is generated from both friction and the process of combustion, causing a rise in engine temperatures. Engine lubricants like oil can help trap and transfer heat before releasing it via the lubrication circuit, assisting the dedicated engine coolant, which can only work to cool certain engine parts. Avoiding the issue of overheating is key if engines are to work effectively.

3. Cleaning

Engines need to stay clean to remain in healthy operating condition. Over time, microscopic deposits like dust and dirt, along with residue from combustion, will build up in engines as they run. Without an effective lubricant, these deposits and debris would clog up the engine and impede its performance. This is because as the engine lubricant flows, it collects and carries any impurities present safely away from key components

4. Sealing

Finally, an engine lubricant must also protect parts by sealing them. As a continuous supply of oil is pumped though the engine, individual components like cylinders and pistons are coated with a thin but durable film. It is understood that fuel combustion results in corrosive acids that can cause harm to engine parts. Additionally, when steel engines components are exposed to oxygen and moisture, iron oxide can occur causing damage. Modern engine lubricants include protective and preventative additives that defend against corrosive acids and rust after sealing off key components.
