PC-11 oils likely to cost more—will it be worth it?
In December a new Proposed Category 11 (PC-11) heavy-duty diesel engine oil hit the market. Composition of the new oil (also called API CK-4 and API FA-4) can withstand higher operating temperatures of late-model engines without sacrificing protection and helps manufacturers meet fuel economy goals.
To show how the benefits of the new oil offset the potential cost increases, Chevron is testing its formulations on a variety of on-road and off-road equipment. Three farmers and two agricultural hauling companies tested the oils on 90 John Deere and Case IH tractors, along with 30 Ford F-350 diesel trucks.
“It was a good opportunity to see it perform in a lot of different conditions,” says Len Badal, Global Delo Brand Manager for Chevron.
The testing showed a 10% to 15% reduction in wear and gave many tractors the opportunity to move from a 500-hour drain interval to once every 750 hours.
The PC-11 category has no known adverse effects on existing equipment, Badal says. That said, farmers can still use CJ-4 oils—if they can find it.
“By the middle or end of this year, it might be hard to find,” Badal explains. “Most oil manufacturers will be moving to CK-4.”
