1. Carpool

Sometimes it's hard to swallow your pride and ride in the back seat. And sometimes it's even harder to spend even more time with your co-workers. But you have to think of carpooling like this: If your car gets 25 miles per gallon with one person, then it effectively gets 50 miles per gallon if two people are riding in the same car.

If you're always the one doing the driving, it should be no problem to split the cost of gas with your co-riders. Alternately, each person in the carpool should take a turn driving, so that fuel costs even out among the group.

Carpooling comes with another added benefit: Riding with others also lets you take advantage of your city highways' HOV lanes, allowing you to fly past traffic with less stops and starts -- saving time, fuel and money.

2. Keep Your Cool on the Road

The car resource experts at ran a full battery of driving tests to see how well driving calmly would improve fuel efficiency over aggressive driving... and the results were phenomenal.

When comparing aggressive drivers (75-80 mph speeds, sharp accelerations, fast braking) to calm drivers (using cruise control at a speed of 65 mph or lower, slow accelerations and coasting rather than braking), the group saw fuel economy improve from 24.5 mpg to 32.5 mpg. That's a fuel economy boost of 35%!

So don't speed, don't tailgate and don't gun it off the starting line and you'll thank yourself when you have all that extra money left in your bank account.

Gas Savings: Up to $586 per year, depending on how aggressively you currently drive.

3. Use Traffic-Fighting Sites and Gas Apps

4. Plan and Combine Errands

You drive to the grocery store to pick up eggs for breakfast. Then you head back out to drop by the bank an hour later. Then you realize that you need to go to the post office. Sound familiar?

Not planning your route can cause a whole lot of back and forth driving. Stop wasting time and gas; in the morning after you've had your coffee, write down all the errands that you would possibly need to do for the day. If the post office and the bank are close to each other, swing by both of those and get them done, then head out to the grocery store and do another errand that's close by before coming back home.

Your car's engine is the most efficient when it's fully warmed up, so not only will combining errands save you time, your car will get its highest MPG and you'll save even more gas from avoiding unnecessary extra trips.

5. Shop Online or Call Ahead

Shopping causes us to drive a lot more often than necessary. According to the Bureau of Transportation Statistics, 45% of all car trips are for shopping and errands.

Why not try shopping online instead? Most of your favorite stores offer the same products online and many have free shipping. (Nasdaq: AMZN) offers free shipping on orders as small as $25.

If you're intent on going to the brick-and-mortar store but you're not sure they carry what you want, give them an old fashioned and FREE (no gas required) phone call; they'll be happy to tell you if it's in stock and you know you won't be wasting a trip.

Gas Savings: $185 or more (8 mile round trips to the store, three times a week) depending on how often you go shopping and how far you live from the store.
