 Adoption of CK-4  
 and FA-4 engine  
 oil since 2016 
 In December 2016, the North  
 American lubricants industry witnessed  
 its biggest specification  
 overhaul in history with the launch  
 of the new American Petroleum  
 Institute CK-4 and FA-4 heavy  
 duty diesel engine oils.  
 Fleet Maintenance magazine  
 has conducted reader studies to  
 monitor the awareness, impact  
 and adoption of these new oils  
 among fleets. Those results  
 were published in the 2017 Fleet  
 Maintenance Oil Study, and since  
 then more fleets are implementing  
 the new oils. But still, a large  
 percentage are unaware of the  
 new oil specification. 
 Last year, 33 percent of fleets  
 indicated they would start using  
 CK-4 immediately in all vehicles  
 since the oil is backwards compatible, 
  28 percent indicated they  
 would adopt FA-4 usage in all new  
 vehicles and 26 percent were not  
 aware or had not started planning.  
 Since then, 60 percent of fleet  
 operators currently use, or plan to  
 use, FA-4 oil for some or all of their  
 vehicles. Notably, the majority of  
 fleets said they have not encountered  
 any obstacles in implementing  
 the oils.  
 Still, 28 percent of heavy duty  
 fleets in the most recent study  
 indicated they are not aware of  
 the oils or had not started planning. 
  This could indicate a need in  
 the industry for more education, or  
 support from oil companies.   
 As more fleets begin to use the  
 new oils, understand their compatibility  
 and see their benefits,  
 it is anticipated that there will  
 be more widespread utilization  
 across heavy duty fleets.  -Vesna
