Good, Better, Best: How to Improve Gas Mileage [align=center]Whether you are shopping for a new car or just trying to maintain the one you have, you can take some steps to get the best mileage out of your gas purchases. The Federal Trade Commission (FTC), the nation’s consumer protection agency, offers these tips to use fuel efficiently: [/align][ul][*][align=center]Stay within posted speed limits. Gas mileage decreases rapidly at speeds above 60 miles per hour. [/align][*][align=center]Stop aggressive driving. You can improve your gas mileage up to five percent around town if you avoid “jackrabbit” starts and stops by anticipating traffic conditions and driving gently. [/align][*][align=center]Avoid unnecessary idling. It wastes fuel, costs you money, and pollutes the air. Turn off the engine if you anticipate a wait. [/align][*][align=center]Combine errands. Several short trips taken from a cold start can use twice as much fuel as one trip covering the same distance when the engine is warm. [/align][*][align=center]Use overdrive gears and cruise control when appropriate. They improve the fuel economy of your car when you’re driving on a highway. [/align][*][align=center]Remove excess weight from the trunk. An extra 100 pounds in the trunk can reduce a typical car’s fuel economy by up to two percent. [/align][*][align=center]Avoid packing items on top of your car. A loaded roof rack or carrier creates wind resistance and can decrease fuel economy by five percent. [/align][/ul][ul][*][align=center]Keep your engine tuned. Tuning your engine according to your owner’s manual can increase gas mileage by an average of four percent. Increases vary depending on a car’s condition. [/align][*][align=center]Keep your tires properly inflated and aligned. It can increase gas mileage up to three percent. [/align][*][align=center]Change your oil. According to the U.S. Department of Energy (DOE) and Environmental Protection Agency (EPA), you can improve your gas mileage by using the manufacturer’s recommended grade of motor oil. Motor oil that says “Energy Conserving” on the performance symbol of the American Petroleum Institute contains friction-reducing additives that can improve fuel economy. [/align][*][align=center]Check and replace air filters regularly. Replacing clogged filters can increase gas mileage up to ten percent. [/align][/ul][ul][*][align=center]Your owner’s manual recommends the most effective octane level for your car. For most cars, the recommended gasoline is regular octane. In most cases, using a higher octane gas than the manufacturer recommends offers no benefit. Unless your engine is knocking, buying higher octane gasoline is a waste of money. [/align][/ul][ul][*][align=center]Be skeptical of claims for devices that will “boost your mileage by an extra 6 miles per gallon,” “improve your fuel economy up to 26 percent,” or the like. EPA has tested over 100 supposed gas-saving devices — including mixture “enhancers” and fuel line magnets — and found that very few provide any fuel economy benefits. The devices that work provide only marginal improvements. Some “gas-saving” devices may damage a car’s engine or increase exhaust emissions.

but a 2x4 under your accelerator.... works better than anything i know

 

run some sea-foam in the tank about once every other month.... and if going on a long trip get three cans. put one in the week before you leave.. one in when you fill up.. and one on the way home... I live right outside Richmond Va and went to hatteras last labor day and did this and drove from here to hatteras and all around the outer banks upon topping off at the border station at the NC/VA line I put in 10 gallons and had gone 456 miles. with using sea-foam and chevron 87 octane and amsoil synthetic oil and keeping car clean and a good coat of wax I avg 34-36 mpg on hwy and about 29-31 in the city. even doing the three can trick going to visit family in sw VA through the mountains I avg 37-38mpg pulling up the hills. I also have the Michelin Energy MXV4's on her with perssure set at 34. hope this may help someone out there with the price of gas now a days

 

sorry forgot to mention my ride is a 03 ls with the 3.4 and 63,000 miles w/no motor mods, just flowmaster exhaust (resonator delete coming soon)
