Chevron Products Co. maker of the Delo brand of engine oils, lubricants and coolants, announced Daimler Trucks North America (DTNA) will begin factory filling with Chevron Delo 400 ZFA SAE 10W-30 (FA-4) starting Jan. 1.

Beginning Jan. 1, Delo 400 ZFA SAE 10W-30 will be factory filled into all Detroit DD13, DD15 and DD16 engines. Chevron Delo engine oils are available upon request via DTNA’s 700+ dealers and its Elite Support dealership network.

“Chevron puts great value on OEM relationships, as they are critical for developing engine oil products which help OEMs lower total cost of ownership for fleet managers,” said James Booth, North America commercial sector manager at Chevron. “We are especially excited about the effect this will have on our factory fill business. As of January 2019, Chevron Delo will supply two thirds of the North American heavy-duty factory fill engine oil market.”
