Cummins ISL Oil recommendation

Brett: I cannot believe that you have not heard of the 2 new oils! I usually look to you for info! FA4 ( was once called PC11) is the oil for newer engines. Not backwards compatible. Apparently the labeling will be different. CK4 is the replacement for CJ4 and can be used in all of the previous diesels. Dig around on the Chevron website and you will see lots of info.

Sorry, still have a couple of cases of "good old" Shell Rotella T, so have not paid any attention to oils recently. Since it was first licensed a little over one month ago, I don't feel too "left out".

Probably one of the more concise explanations: http://rotella.shell.com/products/pc-11.html?gclid=CKjHub3NwNECFeNsMgod83QDPw&gclsrc=ds



What you need to know about CK-4 and FA-4

The new PC 11 category is being driven by changes to fuel economy and emissions regulations that are prompting changes to engine components/sizes and often resulting in hotter operating temperatures.

The Environmental Protection Agency (EPA), the National Highway Traffic Safety Administration (NHTSA) and major engine manufacturers have agreed on ambitious new goals for fuel economy and emissions in future medium- and heavy-duty vehicles. To meet these goals without any compromise in engine protection, a new generation of diesel engine oils is required. First licensing is December 1, 2016.
What is PC-11?

PC-11 stands for Proposed Category 11. The new PC-11 Heavy Duty Engine Oils (HDEO), now called CK-4 and FA-4, due in December of 2016, will surpass current CJ-4 oil technology.
Why do we need a new oil standard?

Oil technology and engine technology go hand in hand. Changing regulatory limits challenge engine manufacturers to reduce emissions. As engine manufacturers begin to create a new generation of cleaner, more fuel-efficient diesel engines, they need a new generation of higher-performing diesel engine oils to protect them. And they need to know those oils will be available throughout the country to every diesel engine owner.
What’s the difference between CK-4/FA-4 heavy duty engine oils and current engine oils?

In order to meet goals for more fuel-efficient engines and fewer emissions, many next-generation engines will run at higher operating temperatures. This will require changes in engine oil composition, so they can withstand more heat without sacrificing engine protection.

It will also mean that instead of one category of engine oils, we’ll have two – CK-4 and FA-4. CK-4 engine oils will be a direct replacement for the engine oils you’re using now. You’ll be able to buy the same viscosity grades and oil types (conventional, full synthetic, synthetic blend) you’re using now, and they’ll be “backwards compatible” to ALL current vehicles. They’ll just also conform to the new PC-11 standards.

The new FA-4 engine oils will be offered in lower viscosity grades and are designed primarily for next-generation engines to help maximize fuel economy without sacrificing engine protection. These FA-4 oils may have limited backwards compatibility2 and would be labeled as such. Oil companies and OEMs are currently testing these products in a range of applications to demonstrate without sacrificing engine protection.
