All heavy-duty engine oils are not created the same. Chevron’s new hard-hitter, DELO® 600 ADF heavy-duty engine oil, is formulated to reduce DPF ash loading. What does this mean for your fleet’s engines? Finally, a heavy-duty engine oil has arrived that minimizes DPF clogging, extends intervals between services, and improves fuel economy. In other words, Chevron DELO 600 ADF engine oil actually lowers operating costs!
The DPF’s job is to filter out ash and soot, and a regeneration cycle combusts most of this soot, but over time, incombustible ash lodges in the DPF and regeneration cycles are less effective. Engine back-pressure and increased regeneration cycles spell out higher fuel consumption.
Once DPFs fail, fleet owners and owner-operators are forced to pull trucks out of service. Of course, the halt in productivity, maintenance costs, and DPF replacements can cripple your business by thousands of dollars.
Chevron DELO 600 ADF prevents this scenario . OMNIMAX®, Chevron’s patented technology, is the secret to this workhorse engine oil, providing maximum system protection to the emissions system and the engine. Industry, OEM, and field tests prove that DELO 600 ADF reduced fuel consumption, extended drain intervals, and prolonged DPF service life.
Do the math: Less ash accumulation in the DPF, lower backpressure, and less frequent active or forced regeneration equals fuel savings.

For mixed fleets, Chevron DELO 400 XLE is the choice. Both DELO 600 and 400 heavy-duty engine oils are available in 10W-30 and 15W-40 to set the standard for DPF protection and optimized drains.
While DPF cleaning recommendations vary according to manufacturer specs, engine condition , and even the lube oil used, most OEMs recommend cleaning DPFs every 150,000 miles.
