Michigan gas prices dropped 5 cents compared to one week ago, AAA Michigan reports.
Drivers are now paying an average of $1.42 per gallon for regular unleaded, the lowest price seen since December 2002.
AAA Michigan says motorists are paying an average of $21 for a full 15-gallon tank of gasoline.
Pump prices have consistently declined for nine weeks, AAA Michigan says.
"An increase in demand may contribute to the slowing of pump price decreases in areas that see an uptick in gas sales, but prices will still be well below where they were a year ago," said Adrienne Woodland, spokesperson, AAA - The Auto Club Group.
