MONTGOMERY — Retail gasoline prices are at their lowest levels in five years, despite higher costs for crude oil.

AAA Alabama says Monday’s statewide average for regular is $1.52 a gallon, down 24 cents since last month.

The national average for regular is $1.61.

Midgrade cost $1.62 and the statewide average for premium is $1.67 a gallon.

Tensions generated by a widening conflict between Israel and Palestinian militants sent crude prices up sharply to above $40 a barrel Monday.
