Emissions analyst Integer Research published the national average price for DEF in the first edition of its new Diesel Exhaust Fluid pricing service, DEF Tracker.

Integer's DEF Tracker shows the pump price fell in 25, or 58%, of the 43 U.S. States offering on-island service between October and November, however, the average across the country increased by three cents per gallon.

There are now four truck stops offering DEF at the pump in Canada, all operated by Pilot Flying J. The price at these locations is CAD$0.80 per liter (3.028 / U.S. gal.).

DEF Tracker is a new monthly service tracking DEF pricing in a number of delivery modes, including pump prices at truck stops, bulk, tote and 2.5-gallon jugs, in cities and U.S. states and Canadian provinces.
