Gregg Laskoski with GasBuddy.com says prices increased in Sacramento last week by more than four cents because supplies are temporarily reduced.
"Refineries are in the process of depleting that winter gasoline inventory," he says, "And then starting maintenance that has to be done before they can start the production of summer blend."
Laskoski says the price of gas could increase by fifty cents/gallon nationwide by May depending on refinery capacity and oil prices. California's increase could be less.
"Crude is up over $100/barrel meaning the West Texas Intermediate Crude," he sasys. "But one of the benefits for Californians is that there is greater access now to lower-cost crude -particularly crude coming in from Canada. That can help reduce some of the impact that we've seen in prior years."
The average cost of a gallon of gasoline in Sacramento is $3.46.
