Saving gas isn't just for tree-huggers anymore

Greenies aren't the only ones looking to limit their car usage these days. High gas prices are fueling inflation for everyone across America.

No matter if you drive a Prius or a Hummer, you can probably stand to save a few bucks on gas right now. Here is our collection of tips for getting the most out of each gallon...

• Use the cruise, clean the car: Forecast Earth covers the classic tricks, such as using cruise control and maintaining your car. This is a great list to begin with.


• Hypermile your way to better mpg: Pulse-and-glide driving is how those ultra-efficient hypermilers get great mileage, even without a hybrid car.


• Carpool at least once a week: Ask around your office and see whose route meets up with yours. Parents can also arrange carpools for driving kids to school. Alternate who drives, and you'll automatically cut gas costs.


• Drive slower: Driving just 10 miles slower can reduce fuel consumption by 20 percent. And no, you won't burn more gas because it takes a tiny bit longer to get to your destination.


• Don't sit idle: When you let your car idle, you might as well light a dollar bill on fire and toss it out the window. It's been proven that stopping and restarting a car uses the same gas as leaving a car idling for 6 seconds with the air conditioner on. Today's fuel-injected cars don't need to warm up in cold weather either.


• Reduce air drag: The Rocky Mountain Institute estimates you can save 15 to 30 gallons of gas per year if you take off a roof rack just half the time. Besides, you only need it for skis when there's actually snow on the ground.


• Ditch the drive-thru: One test in Toronto found that you can get a fast-food breakfast faster and burn less gas in your car if you park and go into the restaurant. Considering how much idling cars do in drive-thru lanes, this isn't surprising.


• Think big, and light: Some of EcoGeek's gas-saving tips are government-based (like intelligent traffic lights and minimum fuel economy; feel free to suggest these to your local and federal representatives!). But everyone can carry less junk in the trunk.

Gas prices may not drop dramatically any time soon. So perhaps you're thinking about a new car -- like a hybrid. They've lost the tree-hugger status and are pretty mainstream. Certainly, SUVs aren't selling very well these days. Need some car advice?

• Rethinking the cost of hybrid cars: The Rocky Mountain Institute compares the Prius to the non-hybrid Accord and Civic and shows how the hybrid comes out ahead.


• Comparing hybrid to hybrid: EcoGeek summarizes the latest findings.


• Getting to know your Prius: A few handy resources for the new owner.


• Finding the best green cars: Yahoo! Autos Green Center is fully loaded with specs on current models, from hybrid to ethanol to ultra-efficient gasoline.

If you have an older car with great mpg and you're wondering if your ride could be even more eco-friendly, check out EcoGeek's analysis of the greenest cars coming in 2010. Just don't fall for a ZAP car or that bunk about running cars with water.
