Gas prices surge: Here are some ways you can save at pump

PHILADELPHIA (WPVI) -- Drivers around the Philadelphia region are on the prowl for gas deals as the price per gallon climbs above $4.

The Phillips 66 in Darby, Pennsylvania was deserted on Wednesday with regular gas going for $4.69.

It was a very different story in Cherry Hill, New Jersey, with regular at $3.93.

Bulk store gas stations are open to anyone in the Garden State, which means Costco is crowded.

"You don't have to have a Costco card," said James Washington of Camden.

Washington is willing to wait for cheaper gas, but didn't want us broadcasting his secret spot.

"This is a geopolitical perfect storm and it's not even full yet," said Dr. Wojtek Wolfe, associate professor of political science at Rutgers University.

If you're looking to save, NerdWallet says the way you pay at the pump can make all the difference.

"You might save money depending on the station if you choose to pay with cash or a debit card," says credit card expert Sara Rathner.

"There are cards that will earn 3-5% cashback at gas stations. That's a card you might want to go for if you have really high bills at the gas station," she added.

In Havertown, Giant customers are loading their trunk and their tank.

"My wife does a lot of food shopping and we get the rewards to put into gas. It's wonderful, especially now," said Don Sergeant of Broomall.

The free grocery store "Choice Rewards Program" can equal big savings. It's a discount of 10 cents a gallon for every 100 points or dollars spent.

"Sometimes it's 10 cents sometimes it's 50 cents. So, definitely with prices rising, it's worth it," said Deb McLaughlin of Springfield.

Here are some other AAA tips to help you save:

Ownership, Maintenance & Repairs

• When buying a car, look for models that offer the best fuel economy in their class. For most drivers, an optional larger and/or more-powerful engine is unnecessary.

• Maintain your car according to the manufacturer's recommendations. Modern cars don't need "tune ups," but regular service will ensure optimum fuel economy, performance and longevity.

• Take your car to a repair shop as soon as possible if the "Check Engine" light comes on. This indicates a problem that is causing excessive emissions and likely reducing fuel economy.

• Keep tires properly inflated. Underinflation reduces fuel economy, but more importantly, tires low on air degrade handling and braking, wear more rapidly and can overheat and blowout.

The Daily Drive

• Slow down and drive the speed limit. On the highway, aerodynamic drag causes fuel economy to drop off significantly as speeds increase above 50 mph.

• Avoid "jackrabbit" starts and hard acceleration. These actions greatly increase fuel consumption.

To idle or not to idle.

• Avoid extended idling to warm up the engine, even in winter. It's unnecessary and wastes fuel.

• Avoid prolonged idling in general. If your car will be stopped for more than 60 seconds, shut off the engine to save fuel. Many newer cars have automatic engine stop-start systems that do this.

• When driving in town, adjust your speed to "time" the traffic lights. This reduces repeated braking and acceleration that consume additional fuel.

• When approaching a red light or stop sign, take your foot off the gas early and allow your car to coast down to a slower speed until it is time to brake.

• Accelerate smoothly with light to moderate throttle. This allows the automatic transmission to upshift into higher gears sooner, reducing engine rpm and saving fuel.

• Use cruise control to help maintain a constant speed and save fuel. However, never use cruise control on slippery roads because a loss of vehicle control could result.

• If your car has a manual transmission, upshift as soon as you can without "lugging" the engine. When practical, you can also save fuel by skip-shifting - for example, going directly from first gear to third.

Don't be Fueled into Wasting Gas

The practices above will definitely help improve fuel economy. Also keep these more general fuel saving tips in mind:

• Minimize your use of air conditioning. Even at highway speeds, open windows have less effect on fuel economy than the engine power required to operate the air conditioning compressor.

• Plan ahead to accomplish multiple errands in one trip, and whenever possible travel outside high-traffic times of day.

• If you own more than one car, use the most fuel efficient model that meets the needs of any given journey.

Fuel Economy Myths

• In hot weather, park in the shade or use a windshield sunscreen to lessen heat buildup inside the car. This reduces the need for air conditioning (and thus fuel) to cool down the car.

• Remove unnecessary and bulky items from your car. It takes more fuel to accelerate a heavier car, and the reduction in fuel economy is greater for small cars than larger models.

• Minimize your use of roof racks and remove special carriers when not in use. On the highway even an empty bike, canoe or ski rack can reduce fuel economy, and a loaded rack or car-top container will have a major effect on gas mileage.

• AAA research has found that unless premium fuel is recommended or required by your car's manufacturer, it provides no added benefit. Motorists should refer to their vehicle's owner's manual to check which type of gasoline is recommended for their engine.
