The New Oils Are Coming!

WASHINGTON, DC… Engine manufacturers needed some help from oil manufacturers to meet new emissions and fuel economy standards and Oil MFGs answered the call by developing Proposal Category 12 (PC-12) oils.

The PC-12 oils were designed for new diesel engines, reducing emissions, helping with fuel economy, and reducing DPF oxidation.  The last time new oil categories were adopted was 10 years ago.  The PC-12 category will begin licensing in January 2027 and soon after product will be available on the shelf.

The American Petroleum Institute (API) is a standards-setting organization that certifies and licenses engine oils.  When the new PC-12 oils are available,  API CL-4  will replace the current CK4 category and  API FB-4 will replace the current FA-4 category. The new API Service Category CL-4 and API FB-4 “Donut” certification marks are now available.

The API offers some DEF Dos and Don’ts:

•If the temperature is too cold, the DEF will freeze, changing the chemical composition.

•If the nozzle is crystalized – do NOT use it!

•If it is too hot, the DEF compound downgrades and won’t work as well.

You can’t control the weather, but maybe when conditions warrant, you maybe be further ahead buying a gallon or two inside.
