How prepared is the U.S. Postal Service for a sudden increase in the price of diesel fuel? When diesel climbed by $2.03 a gallon from March 2009 to March 2012, the USPS’s fuel tab soared by $341 million.
It’s what happens when you operate one of the biggest vehicle fleets in the country: 7,600 of its own in addition to almost 16,000 contract vehicles. In fiscal year 2016 alone, USPS bought about 251 million gallons of diesel at a cost of over $570 million.
