Diesel fuel consumption for the month of April 2018 totaled 37,304,976 gallons, which was a 2.0 percent increase from consumption in the same month in 2017, as shown in the data table below. April 2018's consumption was less than one percent (0.3%) higher than consumption during the previous month. In Figure 1, it can be seen that diesel fuel consumption in April is above the five–year range and last year's consumption for April, and far above the five–year average. Shown in Figure 2, consumption in the last two years has increased bringing consumption out of the plateau seen from 2010 to 2015.
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 Figure 1 below.
