National Average Jumps 10 Cents as Spring Maintenance Ramps Up for Refiners


April 15, 2019 - Pump prices on the West Coast increased as much as 20 cents this past week, driving the national average up nearly 10 cents to $2.83 on the week. As stocks tighten out West due to unplanned and planned maintenance, California’s average jumped to $4.00, the most expensive state average this week and a price point not seen in the Golden State since July 2014.

“We are seeing very expensive gas prices for this time of year across the country,” said Marilyn Buskohl, AAA spokesperson. “Motorists are seeing prices increase as gasoline stocks decreased substantially by 7.7 million bbl amid summer-like demand readings.”

Today’s national average is 3 cents more than last month and 12 cents more than a year ago. South Dakota’s statewide average has jumped 6 cents in a week and 26 cents in a month.

Quick stats

  • The nation’s top 10 largest weekly increases are: California (+20 cents), Nevada (+18 cents), Missouri (+13 cents), Oregon (+12 cents), Alaska (+12 cents), Washington (+12 cents), Utah (+12 cents), Colorado (+12 cents), Idaho (+11 cents) and Kansas (+11 cents).


  • The nation’s top 10 least expensive markets are: Alabama ($2.50), Mississippi ($2.51), Arkansas ($2.52), South Carolina ($2.52), Louisiana ($2.54), Texas ($2.57), Virginia ($2.57), Oklahoma ($2.59), New Hampshire ($2.59) and Missouri ($2.60).

Great Lakes and Central States

With a dime or more increase, Missouri (+12 cents) and Kansas (+10 cents) had the largest one week increases among all Great Lakes and Central states and also both land on the top 10 list for largest weekly increases in the country. Within the region, gas prices range from $2.94 in Illinois to $2.60 in Missouri. 

Gasoline stocks have been consistently tightening in the Great Lakes and Central States since last January. At that time stocks measured at 61.5 million bbl, but the latest EIA report shows total levels today at 52.2 million bbl. This – as well as regional refinery maintenance and the switchover to summer blend gasoline - have caused pump prices to jump as much as 43-cents in the last month in the region.

Oil market dynamics


At the close of Friday’s formal trading session on the NYMEX, WTI increased 31 cents to settle at $63.89. Oil prices increased last week, and will likely continue their ascent this week, as a weaker dollar helped to push crude prices up because of the increased number of dollars needed to purchase crude on the global market. Another contributing factor to the price jumps came from reports that there was a 534,000-b/d decline in crude production by OPEC members in March, led by Saudi Arabia cutting back by 324,000 b/d.
