Diesel Exhaust Fluid Prices Stable in Bulk, Slightly Higher in Tote Jugs
While U.S. national truck stop prices have remained stable for the second consecutive month, the Canadian national average price at truck stops moved back to CA$0.80 per liter after settling at CA$0.81 during the past two months.


The U.S. national average for bulk diesel exhaust FLid prices remained stable for less-than-truckload and tote refill delivery modes, while full truckload deliveries posted a 6 cents per gallon average price increase.
