NEW YORK, April 28 (Reuters) - The average U.S. gasoline

price rose to its highest level in nearly four years, jumping

more than 40% since the U.S. and Israel attacked Iran at the end

of February, according to data from the American Automobile

Association or AAA.

Prices at the pump were near $4.18 a gallon on Tuesday, up

11 cents a gallon in this month and $1.19 a gallon since late

February, AAA data showed.

Gasoline prices could climb further if crude oil prices continue

to surge. Last week, Brent crude futures gained about

16% and U.S. West Texas Intermediate rose nearly 13% on

growing supply worries as efforts to end the Iran war stalled.

Oil prices had taken a breather earlier this month on hopes of

the Strait of Hormuz reopening.

Refinery issues and scheduled maintenance in the Great Lakes

region is expected to keep prices elevated for consumers in the

Midwest, GasBuddy analyst Patrick De Haan said.

BP's 440,000-barrel-per-day oil refinery in Whiting,

Indiana over the weekend experienced a brief power outage that

caused one of its processing units to be shut down.

Phillips 66's 356,000-barrel-per-day Wood River refinery

in Illinois took its crude oil unit and some other parts of the

refinery offline at the end of February for a 45-day maintenance

period.

Marathon Petroleum's ( MPC ) 253,000-bpd Robinson refinery

in Illinois also began planned maintenance in mid-March, with

units expected to remain offline until mid-May.

Retailers in the Great Lakes region might raise prices again

as early as today, De Haan said.
