Texas gasoline prices rose this week for the eighth week in a row.
The weekly Triple-A Texas gas price survey released Friday shows the price of self-serve regular averaging two dollars 89 cents per gallon. That's six cents more than last week and almost 77 cents more than last year's average.
The national average is two dollars 93 cents per gallon -- up a dime from last week.
Auto club spokeswoman Rose Rougeau says prices are nearing the record levels seen immediately after Hurricane Katrina disrupted Gulf Coast refineries last year. But she says prices should start declining by Memorial Day once refineries finish switching over from MTBE-blend fuels to ethanol blends.
The state's costliest gas this week is found in Dallas and Fort Worth, where prices rose six cents to an average of two dollars 96 cents per gallon. The cheapest gas is in San Antonio, where it's averaging two dollars 80 cents per gallon -- up three cents from last week.
