“While it's rare in May to see the national average price of gasoline nearly two cents lower from the previous week, we've seen that retail gasoline has consistently matched (West Texas crude oil's increases and subsequent plateaus since February," said Gregg Laskoski, senior petroleum analyst for GasBuddy.

"In 2015 we saw the national average peak in June and the year before it peaked in April, so while the current plateau may seem encouraging for motorists, we still expect rising consumer demand to elevate gasoline prices as we approach the beginning of the summer driving season," Laskoski added.
