Oil futures fell Friday, retreating from an earlier foray to a new record above $90, as investors sold to lock in profits.

Still, many analysts expect the declines to be temporary and believe oil futures will continue their assault on price records in the days ahead. They say high prices are driven by factors including a weak dollar, speculative investing and low supplies at a key Midwest oil terminal.

Prices at the pump nationally have risen 5.3 cents over the past four days, averaging $2.81 a gallon on Friday, according to AAA and the Oil Price Information Service.

In Lawrence, a gallon of regular unleaded averaged $2.671 on Friday, up 5.5 cents from a day earlier, according to AAA.
