California is the most expensive state for gas with an average price of $5.34 per gallon for regular, followed by Hawaii ($4.69) and Nevada ($4.59).

The Associated Press said the all-time high for average gasoline prices was set in July 17, 2008, at $4.10 per gallon.

In today's terms, the record price would be equal to about $5.24 after accounting for inflation.

"Forget the $4 per gallon mark, the nation will soon set new all-time record highs and we could push closer to a national average of $4.50," said GasBuddy analyst Patrick De Haan. "We've never been in this situation before, with this level of uncertainty. … Americans will be feeling the pain of the rise in prices for quite some time."

Oil prices soared early Monday before retreating. In midday trading, benchmark U.S. crude was up 2% to about $118 a barrel, and the international price gained 4% to around $123 a barrel. Major U.S. stock indexes were down about 2%.
