Chevron oils approved for Cummins natural gas engines
19 May 2023
Chevron Products Company, a subsidiary of Chevron, U.S.A., announced that the Delo 600 ADF 10W-30 and Delo 600 ADF 15W-40 heavy-duty engine oils are approved for use in Cummins mobile natural gas engines.
Chevron Products Company introduced the Delo 600 ADF 10W-30 and Delo 600 ADF 15W-40 oils in 2019 as its first diesel engine oils formulated with OMNIMAX, an ultra-low ash (ULA) technology the company said is designed to solve the problem of ash buildup from engine oil additive packages in diesel particulate filters. It said that the products have been proven to help improve fuel economy retention, forced regenerations and lessen the downtime required to properly service and remove ash from the units.
The Delo 600 ADF oils have now received approval for use in Cummins natural gas engines sold to the on-highway market and are registered to CES 20092. The approval process required two years of field testing, followed by a tear-down of the engines and review by Cummins.
“Shortly after launching Delo 600 ADF, we saw that these products naturally align with Cummins CES 20092 specification for mobile natural gas engine oils,” said Shawn Whitacre, Chevron senior staff engineer. “As the leading manufacturer of natural gas engines in North America, Cummins sets the industry standard for mobile natural gas engine oils. We’re excited that we can now offer fleet operators a single oil for both diesel and natural gas-powered vehicles.”
The ability to have a single oil for both diesel and natural gas-powered vehicles should make managing inventory easier for fleet operators, Whitacre noted, particularly as Cummins prepares to produce a new 15 L fuel-agnostic engine capable of supporting various fuel types, including natural gas.
“With the upcoming launch of a CNG-powered 15L engine, we are already hearing from long-haul operators looking for a one-oil solution for their mixed fleet,” Whitacre said. “Delo 600 ADF delivers all the performance benefits of an API CK-4 heavy duty diesel oil combined with the ultra-low ash technology that helps protect diesel aftertreatment systems while reducing fuel consumption, and now meets the very exacting standards of a natural gas engine oil, as well.”
