Can Your Motor Oil Handle the Seven Responsibilities of a Lubricant?

Can Your Motor Oil Handle the Seven Responsibilities of a Lubricant?

Most motorists understand the primary functions of motor oil: reduce friction and wear. However, motor oil and other lubricants must do more to protect your vehicles and equipment. With engines and equipment becoming more powerful and sophisticated, it takes a properly formulated, well-balanced lubricant to carry out these seven critical functions.

• Minimize Friction

Lubricants reduce contact between components, minimizing friction and wear.

• Clean

Lubricants maintain internal cleanliness by suspending contaminants within the fluid or by preventing the contaminants from adhering to components. Base oils possess a varying degree of solvency that assists in maintaining internal cleanliness. Solvency is the ability of a fluid to dissolve a solid, liquid or gas. While the solvency of the oil is important, detergents and dispersants play a key role. Detergents are additives that prevent contaminants from adhering to components, especially hot components such as pistons or piston rings. Dispersants are additives that keep contaminants suspended in the fluid. Dispersants act as a solvent, helping the oil maintain cleanliness and prevent sludge formation.

• Cool

Reducing friction minimizes heat in moving parts, which lowers the overall operating temperature of the equipment. Lubricants also absorb heat from contact surface areas and transport it to a location to be safely dispersed, such as the oil sump. Heat-transfer ability tends to be a trait of the base oil’s thickness – lighter oils tend to transfer heat more readily.

• Seal

Lubricants act as a dynamic seal in locations like piston rings and cylinder contact areas to prevent contamination.

• Dampen Shock

A lubricant can cushion the blow of mechanical shock. A highly functional lubricant film can resist rupture and absorb and disperse these energy spikes over a broad contact area. As the mechanical shock to components is dampened, wear and damaging forces are minimized, extending the component’s overall operating life.

• Protect

A lubricant must have the ability to prevent or minimize internal component corrosion. Lubricants accomplish this either by chemically neutralizing corrosive products or by forming a barrier between the components and the corrosive material.

• Transfer Energy

Because lubricants are incompressible, they can act as an energy-transfer medium, such as in hydraulic equipment or valve lifters in an automotive engine.

Lubricants do far more than simply protect against wear. High-quality lubricants – like AMSOIL synthetic lubricants – are formulated to excel in each of these critical areas, ensuring you get the most out of your vehicles and equipment.

Squeezing out every MPG – Federal Mogul’s Chief Explains the Future

Federal Mogul’s Explains Technology Will Rest on Engine Oil Quality

AMSOIL position with suppliers and technology forms allows it to get these advanced products out first, keeping ahead of the trends.  Other companies may take months or years before stock holders will allow for decreased profits over top tier additive technology.

This is why AMSOIL has the top reputation when it comes to protection and all out performance to true enthusiasts and those who push their vehicles to the max.

See what Federal Mogul’s Chief Technology Officer, Gian Maria Olivetti has to say in this very well detailed and interesting article.

j-a: How much impact do regional and global differences in fuel quality have on the engineering choices you make? 

GMO: There is still a difference, mainly related to the sulphur content, but it’s a bit more harmonised. You can find 10 PPM everywhere. In Eastern Europe, it’s still a little bit an issue. In China, it’s improving, but it’s still different.

The main issue we have now is the quality of the lubricant. The new generation of engines are going in the direction of very sophisticated low viscosity oils. We are talking about 5W30 to 0W20 and 0W10 and beyond to reduce the friction. That means that you have to put wear improver additives in the oil. Also, you have to have low ash oils that are compliant with aftertreatments.

Oil is becoming sophisticated, and to have sophisticated oil around the world is becoming much more difficult than having good fuel. Availability of quality oil is crucial for reliability.
