Wear Protection in PC-11 Oils: Engine Durability Means Higher ROI

September 02, 2016

We’re continuing our blog series focused on the key traits associated with engine oil and how those will be impacted by the new PC-11 specifications. In this installment, we focus on wear protection — protecting engines from wear is one of the most pivotal functions of the motor oil.

Engine oils are carefully balanced combinations of petroleum base oil and chemical additives that work together to provide effective lubrication of engine parts. It also is critical that the oil maintain its wear protection properties throughout the life of the oil. The new API CK-4 and API FA-4 specifications place new demands on oil performance – and introduce new challenges to ensure that these lubricants are effective even at low viscosities.

Wear protection pays off over the long term. A lubricant that provides robust wear protection helps maximize the life of the engine as a whole, while enhancing the reliability of individual components. This contributes to lower maintenance costs and more time on the road. The net effect is lower total operating costs and a higher return on the investment in your equipment.

 

Key Areas for Wear Protection

When considering heavy duty motor oil (HDMO) it is important to optimize protection in all of the critical areas of the engine, including:

  • Overhead components: providing effective lubrication to the cam, followers, and other valve train components – even when the oil is thickened by abrasive contaminants like soot.
  • Power cylinder: ensuring that the oil is robust to provide lubrication between the piston rings and the liner without breaking down and forming deposits that can lead to other issues including loss of oil consumption control.
  • Bottom end: maintaining sufficient oil film thickness to protect highly loaded bearings, while providing corrosion protection.

 

The performance requirements for wear protection for the new API categories are the same for both API CK-4 and the new lower viscosity API FA-4 specification. This means that you can be assured of the same robust wear protection delivering the same level of performance regardless of viscosity grade.
