Regens stopped

“2013 Freightliner box truck with the small 6, at least 1 forced regen a day, sometimes 2. Mostly city work, only a little highway. 584,000 miles on the clock. Had to park up about 30 minutes each time. The FTC Decarbonizer worked really good. By day 2 the forced regens completely stopped. Another thing, the white exhaust smoke that was always there for a few miles first thing has also completely stopped. Great result. Many thanks.”
