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 $3.547 per gallon on Monday, up $0.035 from a week ago but $0.149 below the same time last year. West Coast prices headed the highest this past week (+$0.055), while the Rocky Mountain region saw a slight $0.018 uptick. 

While gas prices headed higher, diesel prices took a dip, with a $0.018 decrease over the past week to $4.003 per gallon. This latest price tag puts diesel $0.044 per gallon below the same time last year. West Coast diesel dipped the most (-$0.022), while Gulf Coast prices fell just $0.011. 

At these latest prices, the West Coast pays the prettiest penny for gasoline ($3.81) and the East Coast doles out $4.138 for diesel. On the flip side, the Gulf Coast can guzzle gas for just $3.283 and diesel for $3.803 per gallon.
