Changes in direct trends have significantly reduced a patterns of seasonality in U.S. essence markets. Historically, essence use in a United States was rarely anniversary since of a use as a home heating fuel. However, over a past 3 decades, a use as a heating fuel has decreased, distallate fuel exports have increased, and a non-seasonal use as a travel fuel has turn a vital direct component.

Distillate fuel is essentially used for on-highway travel in both light- and heavy-duty vehicles. Distillate fuel is also used as a heating fuel in homes and businesses; as a fuel for certain industrial processes, agriculture, and farming; and, to a obtuse extent, as a fuel for electricity generation.

U.S. expenditure of essence increasing from 2.9 million barrels per day (b/d) in 1985 to 4.0 million b/d in 2015. During this period, a suit of essence used by homes and businesses for heating declined from 28% in 1985 to 11% in 2015 (the many new year with sales information to end-use customers). Meanwhile, a share of on-highway essence use increasing from 40% to 64% from 1985 to 2015.

This trend is even some-more distinguished on a East Coast, a segment with a top thoroughness of residential and blurb heating oil use. The East Coast share of residential and blurb essence use forsaken from 50% in 1985 to 27% in 2015, compared with a share of on-highway transportation, that increasing from 32% to 58%.

Because travel expenditure of essence fuel oil is most reduction anniversary than expenditure of essence fuel oil in homes and businesses, a altogether seasonality in domestic direct for essence fuel oil has significantly decreased.

Another change to U.S. essence markets is a boundary placed on sulfur in essence fuels. Over time, a regulations tying a volume of sulfur benefaction in heating oil and on-highway diesel fuels have converged. Between 2006 and 2010, sovereign (EPA) and state regulations transitioned on-highway diesel fuel to the ultra-low sulfur diesel (ULSD) specification. Starting in 2012, several states in a Northeast gradually lowered a volume of sulfur authorised in heating oil to ultra-low sulfur diesel.

This trend culminated in a NYMEX heating oil futures agreement changing to a ULSD selection in 2013. These changes combined a common essence product that can supply both home heating direct as good as travel direct and does not need apart storage and doing comforts for a opposite fuels.

In a past, essence inventories typically would strech their top annual levels in a late tumble or early winter and afterwards would be drawn down during a winter months. This anniversary settlement was apparent in U.S. essence inventories between a 1945–1946 and a 2007–2008 winter seasons. The winter of 2008–2009 noted a initial time on record that essence inventories increasing over a October-to-March period. More recently, a comparison anniversary settlement in essence inventories has scarcely disappeared, and essence inventories in Mar were aloft than a prior Oct for 3 of a past 5 heating seasons.

U.S. essence exports grew to 1.2 million b/d in 2016 and set a new monthly record of 1.5 million b/d in May 2017. Recently, U.S. essence exports have turn some-more seasonal, offsetting a progressing anniversary trends. From 2009 by 2012, essence exports from Apr by Sep were, on average, 116,000 b/d some-more than those during Oct by March. Since 2013, however, a anniversary disproportion has increasing to 161,000 b/d.
