You can likely file claims of gas-saving gadgets or additives under "too good to be true," but the high gas prices may have some going to extreme measures, even far-fetched ones.
There are few websites the Better Business Bureau is warning about. One reads: Do You Want To Know RIGHT NOW How You Can Drive Around Using WATER as FUEL and Laugh At Rising Gas Costs, While Reducing Emissions and Preventing Global Warming?
Another site touts "little-known products that can actually help you increase your fuel mileage 10%, 20%, 40% and possibly more!”
The BBB says some of these products can actually hurt your car if you try them, though some will cause no damage.
