Cummins approves Chevron for natural gas engines

May 15, 2023

Chevron Delo 600 ADF 10W-30 and 15W-40 heavy-duty engine oils have been approved for use in Cummins mobile natural gas engines. The Cummins’ approval process requires two years of field testing in Cummins engines sold to the on-highway market, followed by a tear-down of the engines and review by Cummins. After putting Delo 600 ADF through this rigorous process, it has now received approval for use in Cummins natural gas engines and is registered to CES 20092.

Delo 600 ADF 10W-30 and 15W-40 were introduced in 2019, offering the first diesel engine oils formulated with Omnimax, a patented ultra-low ash technology designed to solve the problem of ash build-up from engine oil additive packages in diesel particulate filters. Delo 600 ADF 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, according to Chevron.

“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, senior staff engineer, in a statement. “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.

“Having a single oil for both diesel and natural gas-powered vehicles should make life much easier for fleet operators,” said Whitacre. “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. 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 after-treatment systems while reducing fuel consumption, and now meets the very exacting standards of a natural gas engine oil as well.”
