Heading into Labor Day weekend,  gasoline demand remains strong. Data from the Energy Information Administration measures demand at 9.9 million b/d, which is 300,000 b/d higher than the previous week.  Meanwhile, gasoline stocks declined by 2.1 million bbl to total at 231.9 million bbl. While demand chips away at supply, it’s not at a high enough rate to significantly impact gas prices. In fact, the national average is cheaper week-over-week by three-cents. That’s good news for motorists hitting the road for the holiday weekend. They can expect to find the cheapest Labor Day weekend gas prices in three years.
