pumpinggasBISMARCK, N.D. (AP, Feb 1, 2016) – Retail gasoline prices in North Dakota continue to slide.

GasBuddy.com reports the average price of a gallon of gas in the state has fallen to $1.66. The national average is $1.80 – the lowest level in seven years.

AAA’s estimate for North Dakota’s average price is slightly higher, at about $1.68 per gallon. AAA spokesman Gene LaDoucer says the last time the average was lower was March 1, 2004,

GasBuddy.com petroleum analyst Patrick DeHaan says gas prices might continue to drift lower for a while yet, but they’re likely to begin rising in a few weeks because the price of crude oil has rebounded above $30 per barrel.

LaDoucer says he still expects North Dakota’s annual average for this year to be the lowest in more than a decade.
