The average US price of regular-grade gasoline has plummeted 19 cents in the past two weeks to $4.86 a gallon.
Industry analyst Trilby Lundberg of the Lundberg Survey said on Sunday that the continued decline comes as crude oil costs also fall.
“Assuming oil prices don’t skyrocket from here, motorists may see prices drop another 10-20 cents as oil price cuts continue to trickle down to street level,” Lundberg said in a statement.
The average price at the pump is down 24 cents over the past month, but is $1.66 higher than a year ago.
Nationally, the highest average price for regular-grade gasoline was in the San Francisco Bay Area, at $6.14 per gallon. The lowest average was in Baton Rouge, Louisiana, at $4.19 a gallon.
According to the survey, the average price of diesel fell 13 cents from June 24 to $5.76 a gallon.
