Chevron recently 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.
According to the company’s recent press release, 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 the 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 Delo 600 ADF 15W-40 were introduced in 2019, and were formulated with Omnimax, an ultra-low ash (ULA) technology that the company says is designed to solve the problem of ash build-up from engine oil additive packages in diesel particulate filters (DPFs).
