Chevron Delo 600 ADF 15W-40

November 2019 Products DT Staff

Chevron Products has announced its heavy-duty engine oil (HDEO) product, Delo 600 ADF with OMNIMAX, a Chevron Patented Technology. Available December 2, the product will deliver maximum system protection to both the engine and the emissions system. Current heavy-duty engine oils are formulated up to the API CK-4 limit of 1 percent sulfated ash. Chevron’s Delo 600 ADF, however, is formulated to 0.4 percent sulfated ash which helps drastically reduce the rate of Diesel Particulate Filter (DPF) clogging, to deliver extended DPF service life and groundbreaking fuel economy retention. All of this ultimately contributes to reducing operating costs.

Delo 600 ADF meets or exceeds API CK-4 & OEM specifications; it has demonstrated excellent oxidation stability in industry, OEM and field tests, providing the opportunity to extend engine oil drain intervals. Sharing the durability legacy of Delo 400 products, Delo 600 ADF also has delivered excellent valve-train wear protection and piston deposit performance.

It sets you apart from others and in the truck scene, only 250 lucky diesel pickup enthusiasts will have the honor of saying they own and drive the slick design of the 2021 Ford Shelby F250 Super Baja.
