    Fueling Fact or Fiction?
    By Abe Aamidor for the Indianapolis Star
    March 21, 005

    With gas prices at record highs, it's time to learn the truth about maximizing your miles per gallon.

    When it comes to cars, tips on how to save gasoline rank with the Ten Commandments.

    But what do you really know about fuel economy? With gasoline prices hovering at or near record prices in recent days -- and the peak summer vacation travel season yet to come -- it's time to put up or shut up.

    Take the following "True or False" quiz to measure your GQ (that's short for Gas Quotient).

    TRUE OR FALSE?

    1. Always inflate your tires to the "maximum" pressure as embossed on your tire's sidewall.

    2. Cleaning out the trunk of your car will improve gas mileage.

    3. In summer, turn off your air conditioning and roll down the windows to save fuel.

    4. High-octane fuel gives better gas mileage than "regular."

    5. Manual-transmission cars provide better fuel economy than automatics.

    6. "Amazing new discovery improves gas mileage 72 percent!"

    7. Cruise control helps save fuel in flat terrain, but not hilly terrain.

    8. In summer, buy gas during the coolest part of the day to get more gas for your money.

    9. Gas/electric-hybrid cars aren't much better at fuel economy than traditional gas-powered cars, in spite of all the hype.

    10. Buy the cheapest brand of gasoline -- it's all the same anyway.

    i know, i didn't have time to finish my post.

    anyway...these are the ones i got wrong:
    #1-this can be considered true, because properly inflated tires do assist in your car getting the best mileage.
    #3-i drop about 50-75 miles per tank (my average in summer is 375-395)by using the AC. when i roll my windows down, my mileage doesn't drop as much, maybe 20-30 miles. I drive mostly highway miles as well.
    #8-often i don't have time to think about what time of day I get gas. it's usually when my 'low fuel' light comes on. i then have 22 miles to find a station.
    #9-whodathunkit? i went to the Mpls Int'l Auto Show this weekend, and the hybrids were the big stars...

    TRUE OR FALSE?

    1. Always inflate your tires to the "maximum" pressure as embossed on your tire's sidewall.

    False

    2. Cleaning out the trunk of your car will improve gas mileage.

    Kind of True - Removing undo weight from the car can reduce the amount of fuel required to accelerate at a given rate


    3. In summer, turn off your air conditioning and roll down the windows to save fuel.

    False - Just use less gas pedal. :) I'd bet wind resistance created by rolling down windows is worse for economy

    4. High-octane fuel gives better gas mileage than "regular."

    False - High Octane fuel is HARDER to burn than lower octane fuel. Higher octane is to protect the engine from pre-detonation. In fact, on my personal car, I get 2mpg increase by running 89 Octane fuel, compared with 92 Octane. (19mpg on 89, 17mpg on 92 - on average)

    5. Manual-transmission cars provide better fuel economy than automatics.

    True Less gas pedal...when you let off the gas to shift, you are reducing gas consumption.

    6. "Amazing new discovery improves gas mileage 72 percent!"

    False - Snake Oil


    7. Cruise control helps save fuel in flat terrain, but not hilly terrain.

    False- I'd bet CC saves fuel in all situations.

    8. In summer, buy gas during the coolest part of the day to get more gas for your money.

    True - Not sure why...but, sure..why not? :) Less gas 'vapor' more 'gas'?

    9. Gas/electric-hybrid cars aren't much better at fuel economy than traditional gas-powered cars, in spite of all the hype.

    False - They are MUCH better...especially in-town. On the freeways, however, there is less of a gap in mileage. Most of the new hybrids get better mileage by a decent amount, while driven in town. While at slower speeds, the vehicle uses more electric motor, as opposed to more gas motor at freeway speeds.


    10. Buy the cheapest brand of gasoline -- it's all the same anyway.

    False - Detergents added to gas from better companies can do a good job of reducing deposits, on gas-touching parts.

    So the moral is, live in town close to your job so you never have to travel on the freeway, and you'll get great gas mileage.

    Hybrids still offer great mileage on the freeways...just 'better' in town, where they can use the electric motor more. :)
