Diesel fuel consumption for the month of June 2016 totaled 38,054,427 gallons, which was a 5.7 percent increase from consumption in the same month in 2015. As shown in the graphs and data table below, June 2016's consumption was 9.0 percent higher than consumption during the previous month.
Diesel fuel consumption has been relatively stable each month from year to year. Total consumption for 2015 was 414,120,471 gallons, which was a 0.4–percent increase from 2014. Total consumption for 2014 was 412,291,001 gallons, which was a 2.8-percent increase from 2013. Total consumption for 2013 was 401,032,560 gallons, which was a 0.3-percent increase from 2012. Total consumption for 2012 was 399,809,509 gallons, which was a 2–percent decrease from 2011. The data table shows incremental increases each year resulting in a 90–million–gallon increase in consumption between 1997 and 2002, and another increase half that size between 2002 and 2007. In 2008 and 2009, consumption fell due to high energy prices. Consumption has seemed to have reached a plateau from 2010 to the present.
An indicator to support high or low consumption of diesel fuel is reported in miles traveled. The number of miles traveled indicate very little difference from year to year although there are small increases that add up when looking at the miles traveled ten years and twenty years ago. A drawback to the miles–traveled data is that the data for passenger cars, recreational vehicles, and diesel trucks are not separated. The driving season for consumers of diesel fuel is traditionally the months between Labor Day in September and Memorial Day in May. The months of June, July, and August should have a lower demand for diesel fuel, but this isn't reflected in the graph below.
