Fuel efficiency has become an extremely important topic in today's world because of rising gas prices, the need to cut our carbon footprints, and the need to cut dependence on oil-rich nations. Check out these great articles on fuel efficiency.
Why do the EPA fuel economy numbers almost always seem to be off base? It has a lot to do with the way the EPA evaluates new cars and trucks for their energy consumption.
You probably know it as the stuff that fuels a gas grill or a Zippo lighter, but that's just the beginning. People are modifying cars to run on the stuff. Learn all about liquefied petroleum gas.
When gas prices rise, people's thoughts naturally jump to alternative fuel sources. Check out these articles to learn all about the growing technology of alternative fuel.
Soybean byproducts are nutritious and healthy. They can also power a car. Find out how soybean and other plant oils as well as animal fats are used to create the environmentally friendly fuel biodiesel.
With fossil fuels in limited supply, the ever-increasing consumption of this commodity causes problems ranging from global warming to dependence on outside oil sources. Hydrogen is a possible fix, and the technology to take advantage of it is already out there. Find out the benefits of and hurdles facing a hydrogen economy.
I've heard that it's possible to build a car engine to run off of ethanol, a byproduct of corn. How much corn would I need to grow in order to produce enough ethanol fuel to drive my car across the country?
Gas is the bloodline that keeps America moving, and tracking prices can feel like a roller coaster ride. They're down one month, up the next, before climbing more than 50 percent in a year.
When people refer to "nitro-burning funny cars" and "top-fuel dragsters" what are they talking about? What is "top fuel" and how is it different from gasoline?
As gasoline continues to lose its cachet as a reliable energy source, auto manufacturers have started to turn toward cleaner-burning fuels. However, they're still trying to figure out how to use the cleanest fuel of all -- the air we breathe.
Hydrogen gas is hard to store, so fuel processors are crucial to most commercial fuel cells. Learn how fuel processors supply the hydrogen and how efficient they really are.
I know that the faster I drive my car the more gas it uses. But on the other hand I'll get to my destination in less time. Is there a "sweet spot" on the speedometer that would give me maximum fuel efficiency? And if so is it different for different car models?
Why are governments, private businesses, and academic institutions collaborating to research develop and produce fuel cells? Learn how fuel cells work and how efficient they really are.
I have read the question about crude oil and the different types of fuel. I was wondering: if gasoline is an aliphatic hydrocarbon why doesn't it burn cleanly forming just CO2 and H2O?
We are all familiar with gasoline-powered cars, and most people have heard about or seen electric cars. So what exactly is a hybrid car?
I have heard that both race cars and some motorcycles (like Harley-Davidsons) use a dry sump oil system. What is the advantage of a dry sump?
Adding a chemical called tetraethyl to gasoline can significantly improve the gasoline's octane rating. So what does octane mean? Read on to find out.
If you have ever pumped gas that claimed to "oxygenated" -- something that is common in most urban areas in the winter -- then you have used gasoline containing MTBE.
Gasoline, kerosene, diesel, etc. all come from crude oil, but what makes them different? Read on to learn about their differences.
The short answer is: yes. You could compress the air at your house using an air compressor fill a compressed-air tank in the car and the car could run off of it. But it's not quite that easy. Find out why.
Planning to change your own oil? You're probably wondering what the numbers on the can of motor oil mean. Find out what they mean and what oil is best for your car.
