Gas

Drivers who have seen a steady rise in the price of gasoline can relax: They will almost certainly be paying far less for gas this summer than they have in at least six years.

With more money in their pockets thanks to lower gas prices and an improved job market, AAA expects more than 37 million Americans to travel for Memorial Day, the most since 2005.

Naval warfare, aerial warfare, logistical warfare, cyber warfare. There are as many ways to wage war as there are stars in the sky, but economic warfare is perhaps one of the most misunderstood. It's rarely as overt as bombing factories or sinking freighters, featuring more subtle, domestic maneuvers.

Gas prices traditionally take a dive come winter, as demand cools faster than the daily temperature and producers switch to the cheaper "winter blend" of gas. That, however, doesn't account for the precipitous fall in prices, with 2014's nationwide average $3.69 high point, to last week's average of just $2.79. In fact, prices are expected to dive even further in the coming weeks.

AAA's predictions of cheap gas for the coming fall season are already being realized. Gas prices across the country are dipping to the lowest levels seen in almost four years.

AAA's predictions of cheap gas for the coming fall season are already being realized. The cheapest average price for the whole year was beat Wednesday, as the average cost of a gallon of unleaded hit $3.27, beating February's price of $3.29.

The good news, for the domestic fossil fuel types, is that US oil production went up. The better news is that more people bought hybrids, plug-ins and high-fuel-economy vehicles, theoretically cutting their gasoline purchases as a result. And yet there remains some bad news for the domestic economy, as average US household spending on gasoline neared record highs last year.

Okay, okay, okay – it's not as bad as that headline says it is. First of all, even if we did only have 53.3 years of oil left, it'd represent a 1.1-percent improvement over last year's estimate, to 1.69 trillion barrels of oil left. But more importantly, we probably have a hell of a lot more oil left than that. Of course, a lot of it comes from shale, which means fracking, which isn't exactly great for the environment. So, it's not all roses here.

At the end of the month, Missouri will begin to allow the sale of the controversial E15 fuel. Currently, most available gasoline is sold as a blend with up to 10 percent ethanol. Missouri will become the 13th s

Shell invited us to its Technology Center near Houston, Texas to learn more about its V-Power premium gasoline, and we ended up learning not only about detergent additives but also what the Internet thinks happens inside a car's engine. In Part One of the story of our visit, we tackled the Internet and the engine internals, laying out the ways in which some of your engine's parts get layered in

Two of the most important additions to a car are also two of the most commonly ignored: gasoline and tires. Companies pour staggering amounts of money, energy and resources into designing, engineering and gaining percentile improvements in automobiles, and what they get in return from consumers is a staggering amount of "Which one is cheapest?"

Here's a welcome holiday present for motorists - gas prices may fall below $3 a gallon before year's end, with some 35 states already reporting at least one station with prices below the mark, according to a report from CNBC. That's a big drop from the current $3.25/gal national average, and it could expand.

In the age-old debate of whether government regulations help or hinder economic growth, here's one example where more rules have helped create American jobs.

Compared with the rest of the world, the U.S. has long been known as the gas guzzler country--the nation of the widest roads, largest vehicles and the least amount of reliable mass transit for the geography. That image could be changing, according to a new study that says driving in the U.S. has already peaked and will decline.

The US Supreme Court has effectively rejected an effort to block sales of gasoline blended with 15-percent ethanol content (E15), refusing to hear a lawsuit and leaving in place an earlier ruling by a federal appeals court that confirms the fuel is legal to sell.

Fleets can save well over $150,000 in fuel costs over the six-year life of a truck.

A car that could run on thin air? On the road by 2016? That's what Peugot-Citroen says it will be selling: A hybrid car that runs on a combination of gasoline and air.

AAA has asked the EPA to stop sales of a new blend of gasoline, asserting that the fuel can cause damage to car engines and could void warranties.

After the flooding and power outages, one of the biggest impacts Superstorm Sandy has had in the Northeast remains a rash of gasoline shortages. To get around the problem, Fei Teng, a 42-year-old sushi chef at a Manhattan restaurant called 1066 ENO, was reportedly hoarding gas in the restaurant's basement using soy sauce buckets. How do we know this? According to the New York Daily News, another restaurant employee accidentl

As Hurricane Sandy -- also known as the "Frankenstorm" -- closes in on the eastern coast of the United States, drivers should begin preparing for an increase in the price of gasoline.
