Power Service, a maker of diesel fuel additive technology, released new field and dyno performance data marking one year since the launch of Diesel Injector & DPF Flush.
In a 20-tank commercial field study evaluating 2025–2026 GMC Sierra 1500 Duramax platforms, a regular treatment regimen of Diesel Injector & DPF Flush and Diesel Kleen + Cetane Boost delivered a 60.20% increase in DEF efficiency and an 11.53% increase in fuel economy. Drivers traveled 60.2% farther between DEF fill-ups, extending the driving range of a standard 5.4-gallon DEF tank by over 2,500 miles per tank and effectively cutting required refills nearly in half.
This drop in DEF consumption proves that aftertreatment demand begins with the injectors. When internal diesel injector deposits are cleared, fuel spray patterns improve, and fuel burns thoroughly inside the cylinder. That complete combustion extracts maximum power from every drop of fuel.
Cleaner in-cylinder combustion minimizes soot buildup on the DPF, significantly reducing fuel-wasting active regens and easing the workload on the Selective Catalytic Reduction (SCR) system, which lowers the volume of DEF required to control emissions. This data is further corroborated by controlled dynamometer testing showing an immediate 6.9% to 8.5% increase in peak torque and horsepower.
At today’s diesel prices, the fuel economy gains alone could save a typical diesel pickup driver about $600 a year, or roughly $20 every time they fill up. The results come as diesel prices reach historic highs, with the national average near $6.30 a gallon, according to AAA.
Powered by REGENEXTEND, a proprietary formula developed by Power Service, Diesel Injector & DPF Flush tackles deposits throughout the system, including injectors, turbo components, EGR and DPF, while helping reduce regen frequency and duration by up to 50%.
Drivers can expect cleaner injectors, optimized combustion, reduced carbon buildup and improved fuel efficiency, whether hauling long distances or navigating stop-and-go traffic.
Diesel Injector & DPF Flush works across all diesel-powered vehicles, including commercial fleets, farm equipment and personal pickups. Available in 12 oz, 26 oz and 64 oz sizes, it can be used routinely or as needed for a system flush.
Diesel Injector & DPF Flush is available at Walmart, Amazon, Atwoods, Blain’s Farm & Fleet, Bomgaars, Love’s Travel Stops & Country Stores, Pilot and Flying J, Rural King, Tractor Supply Company, TravelCenters of America and Petro Stopping Centers, as well as through Power Service’s distributor network.
