Diesel down 1.3 cents to $1.984

The average national price for a gallon of diesel dropped 1.3 cents last week to $1.984. However, demand is expected to pick up as unusually mild weather in the U.S. has recently come to an end, which could halt the recent streak of price drops.

Pump prices in the Rocky Mountain region took the steepest dive, with a 6.1-cent drop to $1.988. The Gulf Coast was the only region that posted an increase, up 1.2 cents to $1.922. The Gulf Coast remains the cheapest region to fill up, however. California once again averaged the most expensive diesel, despite a relatively deep 5.1-cent price cut to $2.081.
