PC-11 : TOTAL future generation oils are coming to you
Regulators set more stringent greenhouse gas emissions limits obliging engine manufacturers to make cleaner and more fuel efficient diesel engines. Oil makers are required to produce new oils for these new engines. OEMs are also looking for improvements in oil oxidation control, aeration control and shear stability.
PC-11 in a nutshell
The next generation of Heavy Duty Engine Oils is coming, establishing new industry standards to deliver significant improvements in engine protection and fuel economy. As everyone in the industry would know by now, the new diesel engine oil specification is due to hit the market on Dec. 1 2016: API CK-4 and FA-4. In the development phase, these oils have been referred to as PC-11A and PC-11B respectively.
Both deliver superior performance over current oils. The former will protect new and older engine models. And the latter was designed to provide optimized fuel economy for 2017 engines and beyond that are designed to take advantage of these improvements.
CK-4 oils replace CJ-4 oils with the same viscosity grades and oil types (mineral/synthetic) and are backwards compatible down to CF-4. FA-4 oils are lower in viscosity grades to help maximize fuel economy without compromising durability for next generation engines. However, they are limited in backwards compatibility.
The introduction of the new PC-11 engine oil performance category will result in the largest change in oil specifications that the industry has seen in a generation. These new categories resulted from years of collaborative effort between the oil and additive industries and diesel engine manufacturers. What is different about the development is API’s introduction of two diesel engine oil standards at the same time.
