    "Over the last week, the national average has continued to see a ever so slow downward trend," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan in a news release. "But the downward trend got a shot in the arm last weekend as we saw the biggest daily drop since April, from July 25 to July 26, the average dropped 1.5 cents.”

    He continued: “Back on April 13, the U.S. average dropped 1.7 cents from the previous day. Further illustrating the downward trend, five percent of the country was over $4 a gallon Friday. Last week, seven percent of the country was over $4 a gallon.”
