---- — Reversing a period of small declines, regional and national gasoline prices turned slightly higher last week. But the increases amounted to only fractions of a penny in the average prices for self-service regular gas across Massachusetts and New Hampshire, according to figures released by the auto club AAA.
Last week’s increase in the U.S. national average was slightly higher. But overall, last week’s minor changes are a continuation of the price stability that drivers have seen over the last several weeks.
Massachusetts drivers paid an average of $3.544 per gallon for self-service regular gas on Wednesday, according to AAA. That was 0.6 cents higher than the prior Wednesday’s average of $3.538. On the same day of 2012, the Bay State average of $3.549 was 0.5 cents higher than Wednesday’s level.
In New Hampshire, the state-wide average inched 0.8 cents higher last week, reaching $3.481 on Wednesday from $3.473 seven days earlier, the auto club reported. On the same day last year, the state’s average of $3.521 was 4.0 cents higher than Wednesday’s figure.
The national average rose 1.7 cents over the period, with AAA compiling a U.S. figure of $3.634 on Wednesday, compared to $3.617 a week earlier. Wednesday’s coast-to-coast average was 9.2 cents higher than the $3.542 reported on the same day last year.
