Americans are paying more at the gas pump this week, according to an Energy Information Administration report released Monday.

The national average price for regular gasoline clocked in at $3.704 per gallon on Monday, up $0.018 from a week ago and $0.127 above the same time last year. While Rocky Mountain prices jumped an unusually large $0.076 over the last week, Midwesterners enjoyed a $0.021 week-to-week decline -- the only drop. 


Diesel prices also increased nationwide, rising $0.037 per gallon over the past week to $3.919. This latest price tag puts diesel $0.081 per gallon above the same time last year. West Coast prices went up the most ($0.059), while the Rocky Mountain region notched only a $0.021 bump. 


At these latest prices, the West Coast pays the prettiest penny for gasoline ($4.011) and diesel ($4.053), while the Gulf Coast can guzzle gas for just $3.494 and diesel for $3.813 per gallon.
