Chevron announced that its 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.

Delo 600 ADF 10W-30 and Delo 600 ADF 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 (DPFs).

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, Chevron has now received approval for the oil's use in Cummins natural gas engines and is registered to CES 20092.

Chevron said the Delo 600 ADF products have been proven to help improve fuel economy retention, reduce forced regenerations, and lessen the downtime required to properly service and remove ash from the units.

“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. “We’re excited that we can now offer fleet operators a single oil for both diesel and natural gas-powered vehicles.”

Whitacre said having a single oil for both diesel and natural gas-powered vehicles should make life easier for fleet operators. With the upcoming launch of Cummins' CNG-powered 15L engine, he is already hearing from long haul operators looking for a one-oil solution for their mixed fleet.
