RS190: What Do Fleets Get Wrong About Aftertreatment Total Cost of Ownership?

Why It Matters

Understanding the true cost and performance of after‑treatment restoration enables fleets to cut downtime, lower fuel expenses, and stay compliant with evolving emissions rules, directly boosting profitability per mile.

Key Takeaways

• Traditional DPF cleaning removes only 30‑50% of ash, limiting mileage.
• Full restoration extracts 95%+ ash, restoring near‑new filter performance.
• Restoration extends service interval to full 350,000 miles versus 125,000.
• Tracking regen frequency and labor rates reveals true after‑treatment TCO.
• Proactive restoration programs reduce downtime, fuel consumption, and overall cost.

Summary

The Road Science podcast episode examines why many fleets miscalculate the total cost of ownership (TCO) for after‑treatment systems and confuses simple “cleaning” with true component restoration.

Hosts hear from Ceramax North America’s JT Robersonson and Matt Brady, who explain that conventional “bacon‑blow” cleaning extracts only 30‑50 % of soot and ash, while an aqueous restoration process removes more than 95 %, effectively returning a diesel particulate filter (DPF) to near‑new condition. That difference translates into a full 350,000‑mile service interval versus roughly 125,000 miles after a basic clean, and it directly influences fuel consumption, regen frequency, and shop labor costs.

Robersonson emphasizes that fleets should monitor regeneration events and labor rates as primary TCO metrics, noting that rapid regens spike fuel burn and signal a pending restoration. He also cites the “bacon‑blow” as an outdated “mousetrap” and stresses that a proactive restoration schedule—often supported by exchange programs—eliminates unexpected downtime and provides predictable maintenance windows.

Adopting restoration over cleaning lets operators convert a reactive expense into a strategic cost control lever, improving uptime, reducing per‑mile fuel penalties, and keeping emissions systems within tightening regulatory limits. For fleet managers, the shift means more accurate budgeting, longer component life, and a clearer path to meeting both profitability and compliance goals.

Original Description

Aftertreatment is one of the most misunderstood—and costly—parts of fleet operations. Fleets often focus on invoice price or treat DPF service as a reactive event rather than a preventive strategy. The result is increased downtime, unpredictable failures, and a cost per mile that quietly climbs.

Recorded live at TMC’s 2026 Annual Meeting, co‑host Michael Freeze sits down with Ceramex North America experts JT Roberson and Matt Brady to unpack what fleets consistently get wrong about aftertreatment total cost of ownership. Discover the real difference between basic DPF cleaning and true restoration—and why those decisions matter for cost per mile, downtime, and emissions compliance.
