DEF Tracker: DEF Pump Prices are Up

The average price of U.S. diesel exhaust fluid rose 4 cents from September and October, to an average of $2.80 per gallon, reports DEF Tracker. This is the second highest average pump price in the last 12 months, behind June at $2.88 per gallon.
The report also notes that bulk DEF dispensing facilities at truckstops reached its highest level since DEF Tracker was launched in October 2011, with 77 new locations coming over the last 30 days.
"Reductions in raw material costs and moves by distributors to capture market share have caused DEF prices to decrease in tote refill, and FTL and LTL bulk delivery modes during October," said Christopher Goodfellow, North American Emissions Analyst at Integer Research, publisher of DEF Tracker.
DEF Tracker added price references for Portland, OR, in the October issue, bringing the total number of metropolitan areas covered to ten. Integer is adding additional references on a month-by-month basis.
DEF Tracker is a monthly subscription service giving DEF price references for full truckload and less than truckload bulk deliveries, tote refills and packaged products, and pump prices in every U.S. state and Canadian province.
