With gas prices on the rise this summer, there is no shortage of fuel economy advice available to consumers who want to save a few dollars at the pump. Drivers are often encouraged to improve their vehicle's fuel economy by reducing air conditioning use, changing filters regularly, checking tire pressure, having fuel injectors cleaned and using a fuel additive to increase engine performance. But how likely are consumers to actually use any of these gas-saving tips to help save money?

According to a recent Kelley Blue Book Marketing Research study on fuel economy, nearly six out of 10 consumers say they would be likely to change their filters at scheduled intervals and/or check their tire pressure regularly to achieve greater fuel economy or save money. In addition, nearly seven out of 10 consumers (68 percent) believe that by performing some or all of the recommended gas-saving maintenance to their car, they would save up to $200 annually.

"Gas prices have reached levels that are causing consumers to take steps they may not have when pump prices were more moderate to improve fuel economy and save a few dollars," said Jack Nerad, executive editorial director and executive market analyst for Kelley Blue Book's kbb.com. "If these consumers actually perform all of these gas saving tips, it's likely they could save up to 15 or 20 percent of their entire fuel costs annually."

However, only 23 percent say they would be willing to reduce air conditioning use. Even less popular options include having fuel injectors cleaned (17 percent), and using a fuel additive in each fill-up to increase engine performance (five percent).

More than a quarter of consumers (26 percent) say they would employ all of these recommended fuel-saving tips to achieve greater fuel economy or save money, and a contrasting five percent say they would do none.

When thinking about their next new-vehicle purchase, 69 percent of consumers are likely to change the vehicle they drive in order to improve their fuel economy or money situation: 22 percent would buy a hybrid version of a vehicle they already have; 21 percent would take a step down in vehicle size; 14 percent say they would buy a vehicle with a smaller engine or an engine with less power; and 12 percent say they would buy a diesel vehicle. Thirty-one percent of consumers say they would not change their next vehicle to improve fuel economy.

The Toyota Prius is in its second generation and approaching its fifth model year, and it continues to dominate the hybrid market. However, because the Prius doesn't necessarily fit every lifestyle, the editorial staff at Kelley Blue Book's kbb.com put together a list of fuel-efficient favorites filled with something for everyone.

"We certainly think there is an important place in the market for hybrid vehicles today and in the future," said Jack Nerad, executive editorial director and executive market analyst for Kelley Blue Book's kbb.com. "But today's market offers a wide variety of vehicles that both fill individuals' needs and provide better-than-average fuel efficiency, and this list includes our top choices."
