Gasoline prices set more records at the pump Friday, while gasoline and oil futures prices were mixed after the previous session’s big advance.

Retail gasoline prices rose 1.5 cents overnight to a national average price of $3.129 per gallon, a new high, and have risen 26 cents in the last month, according to AAA and the Oil Price Information Service.

In Lawrence, prices were as low as $3.29 on Friday.

Analysts blame strong consumer demand and a spate of unexpected refinery outages for the high prices, and say it could be mid-summer before they ease.

Meanwhile, gasoline futures for June delivery fell 2.89 cents to settle at $2.4077 a gallon on the New York Mercantile Exchange, with analysts attributing the decline to profit-taking from Thursday’s 9.96-cent increase in the June contract.

Oil futures were up on continued concerns about gasoline supplies, rising 8 cents to settle at $64.94 on the Nymex.
