According to data from AAA, the San Antonio area saw a dramatic increase in gas prices in the past week from $3.31 a gallon to $3.51 per gallon but the increase is even more drastic compared to one year ago when motorists were paying $3.04 a gallon.

As of Thursday, the national average for a gallon of gas is $3.86 based on AAA findings, which is 44 cents more than the average cost of a gallon of gas across Texas.

Diesel drivers are paying even more. The current average for a gallon of diesel in San Antonio is $4.14, which is up 15 cents from one week ago. The current U.S. average for a gallon of diesel is $4.53.

Here’s the cost breakdown for gas prices based on AAA data:
