    Default Tips to improve your Gas Mileage

    Here are some tips to help you reduce the amount of gas you use. If you are already following these tips, you are probably getting the best gas mileage your car can deliver.

    10 Chevy Traverse LT AWD
    02 Chevy Trailblazer LS (110K+ miles - loaded except for 4WD - WRECKED!)
    99 Chevy Cavalier LS (105K+ miles - commuter car)
    78 Chevy Suburban Silverado (454, 3/4 ton)

    Drive Sensibly
    Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, so you may save more than gas money.
    Fuel Economy Benefit:
    Equivalent Gasoline Savings:

    Observe the Speed Limit
    While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 60 mph.
    As a rule of thumb, you can assume that each 5 mph you drive over 60 mph is like paying an additional $0.20 per gallon for gas.
    Observing the speed limit is also safer.
    Fuel Economy Benefit:
    Equivalent Gasoline Savings:

    Remove Excess Weight
    Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2%. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.
    Fuel Economy Benefit:
    1-2%/100 lbs
    Equivalent Gasoline Savings:

    Avoid Excessive Idling
    Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

    Use Cruise Control
    Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.

    Use Overdrive Gears
    When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.

    Note: Cost savings are based on an assumed fuel price of $2.97/gallon

    Keep Your Engine Properly TunedFixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent, though results vary based on the kind of repair and how well it is done.
    Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.
    Fuel Economy Benefit:
    Equivalent Gasoline Savings:

    Check & Replace Air Filters Regularly
    Replacing a clogged air filter can improve your car's gas mileage by as much as 10 percent. Your car's air filter keeps impurities from damaging the inside of your engine. Not only will replacing a dirty air filter save gas, it will protect your engine. Fuel Economy Benefit:
    up to 10%
    Equivalent Gasoline Savings:
    up to $0.30/gallon

    Keep Tires Properly Inflated
    You can improve your gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.
    Fuel Economy Benefit:
    up to 3%
    Equivalent Gasoline Savings:
    up to $0.09/gallon

    Use the Recommended Grade of Motor Oil
    You can improve your gas mileage by 1-2 percent by using the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1-2 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1-1.5 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.

    Note: Cost savings are based on an assumed fuel price of $2.97/gallon.

    Combining errands into one trip saves you time and money. Several short trips taken from a cold start can use twice as much fuel as a longer multipurpose trip covering the same distance when the engine is warm. Trip planning ensures that traveling is done when the engine is warmed-up and efficient.
    With a little planning, you can avoid retracing your route and reduce the distance you travel as well. You'll not only save fuel, but also reduce wear and tear on your car.
    If you can stagger your work hours to avoid peak rush hours, you'll spend less time sitting in traffic and consume less fuel.
    If you own more than one vehicle, drive the one that gets the best gas mileage whenever possible.
    Consider telecommuting (working from home) if your employer permits it.
    If possible, take advantage of carpools and ride-share programs. You can cut your weekly fuel costs in half and save wear on your car if you take turns driving with other commuters. Many urban areas allow vehicles with multiple passengers to use special High Occupancy Vehicle (HOV) lanes.
    Consider using public transit if it is available and convenient for you. The American Public Transit Transportation Association has links to information about public transportation in your state.

    TravelingA roof rack or carrier provides additional cargo space and may allow you to meet your needs with a smaller car. However, a loaded roof rack can decrease your fuel economy by 5 percent. Reduce aerodynamic drag and improve your fuel economy by placing items inside the trunk whenever possible.
    Avoid carrying unneeded items, especially heavy ones. An extra 100 lbs in the trunk reduces a typical car's fuel economy by 1-2 percent.

    Nice. Need to make this mandatory reading before anybody makes another post asking how to increase MPG.

    You can add all the mods you want and hope they'll pay off in 10 years. But none of that helps if you can't stay out of the throttle and follow the basic common sense things listed above.

    Good stuff!

    theres no quick way to save money, or everyone would be doing it. my best piece of advice is to use common sence & and to get a vacuum guage. or a boost guage which ever you prefer (make sure boost guage reads vacuum though). connect vacuum line to inside of intake manifold, and it will read the KPA of vacuum your engine is creating due to the restriction of the throttle plate partially closed and the vacuum the engine creates when the pistons go down

    the higher the vacuum number the better the effiency at 0 kpa or WOT there is no vacuum and the engine is under full load whether accelerating hard or not. example. driving a manual your in 5th gear flooring it and your not accelerating very fast and your rpms are low, and you probably think that your saving gas? your engine is under full load, and since the manifold is under no vacuum, the air is denser, hence it can add more fuel while remaining a stoich combustion. basically in a nutshell its an even balance between RPMs and engine load. balance them off with your common sence. after a couple of weeks, you will subconsiously be driving more economically because youve been at it for a while. pick one up for 30 bucks at autozone get a good one (ex. autometer)

    Well, if none of those suggestions are good enough, just buy one of these.
