DPFs play a crucial role in cleaning diesel exhaust before it hits the tailpipe, reducing emissions of particulate matter. As fuel burns, the DPF collects and stores soot and ash, rather than sending them out the end of the tailpipe.
Most of the ash that collects in the DPF actually comes from consumed lubricant. So the problem isn’t with the DPF, the aftertreatment system, or the strain the vehicle is under. The problem is what goes into the engine. Chevron Lubricants has developed an industry-changing, patented HDEO designed to combat ash clogging in the DPF. Here are the benefits of Chevron Delo 600 ADF.
- As much as 90% of non-combustible matter in a typical DPF is the result of lubricant additive materials and soot.
- Delo 600 produces 60% less sulfated ash compared to other API CK-4 oils.
- With less ash output, they achieve greater fuel efficiency, save dramatically on fuel, increase the time between DPF cleanings, increase uptime, and reduce total operating costs.
- The ash accumulation problem, when left unaddressed, can cost a fleet millions in the form of inefficient fuel consumption and additional DPF cleanings and replacements.
- Delo 600 increases fuel economy retention by up to 3%, drastically reduces the rate of DPF clogging, and extends DPF service life by up to 2.5 times, all while delivering unbeatable wear, deposit and oxidation performance.
