The agency says the slight jump ended a monthlong streak of increases of at least 10 cents per gallon. The average price of gasoline in Texas is $1.01 higher than it was a year ago. Houston had the biggest increase at 3 cents per gallon. The most expensive gas among the 11 cities surveyed is $3.79 in Dallas and Fort Worth. The least expensive is San Antonio at $3.68. State prices are generally 20 cents shy of record levels from the summer of 2008. The national average is $3.84.
