Here's how gas prices have changed in Oregon in the last week

(STACKER) -- The national average price of regular gasoline broke its record high yet again on Monday, reaching $4.52 per gallon, according to data from AAA. Except for Georgia, Kansas, and Oklahoma, every state now has average gas prices above $4.00 per gallon.

In Oregon, pump prices set new record highs in the state, with the average gallon of gas going for more than $5 -- $5.06, to be exact -- for the first time ever, according to AAA.

In addition to high crude oil prices hovering at $114 per barrel, the U.S. is also paying more for summer-grade fuel. Summer gasoline blends, which are federally mandated to be produced between May 1 and Sept. 15, have lower Reid vapor pressure, making them less likely to evaporate in warmer weather. Summer blends can cost an extra ​​15 cents per gallon on average.

Stacker compiled statistics on gas prices in Oregon. Gas prices are as of May 16. State gas tax data is from World Population Review. Two states, Connecticut and Georgia, have temporarily suspended gas taxes to help consumers as the cost of gas increases.
