In December, a new Proposed Category 11 (API CK-4 and API FA-4) of heavy duty diesel engine oil will arrive, leaving some farmers wondering how it will affect their farm machinery.
“This change is coming hot and heavy,” says Len Badal, Global Delo Brand Manager for Chevron. “In agriculture, they’ll see CK-4 products coming at them pretty quickly. If they don’t understand what’s changing, they won’t understand the cost versus the benefit.”
There is potential for cost increases for PC-11, Badal says. Will the benefits be enough to offset it?
To help answer that question, Chevron has been testing its upcoming Delo 400 formulations (available starting Dec. 1) 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,” he says.
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 them.
“By the middle or end of next year, it might be hard to find,” he says. “Most oil manufacturers will be moving to CK-4.”
New API CK-4 and API FA-4 formulations are expected to be available starting December 1, 2016.
