Gas prices can make all those gas gadgets out there look very tempting.
The ads for special filters, fuel pills, and additives promise more mileage on less gas.
12 On Your Side's Ryan Duffy checked it out with one expert who's seen and tried plenty of these gas gadgets.
If one of these gadgets could get you more miles to the gallon, you would probably consider buying it whatever the cost.
Well, with gas prices sky high, the offers for these gadgets that you stick inside your air valve, or pour in the gas tank are all over the Internet.
We asked certified mechanic Aaron Clements about it.
He says he sees an increase in people wanting to try them every time gas prices spike.
But he's never seen one work.
News 12 tested the "Tornado" with Aaron a few months ago and found no noticeable increase in gas mileage...and the product costs $55.
Aaron says if things like this worked, car manufacturers would install them at the factory.
"Hydrogen, aligning the particles, fuel atomization, all these words make it sound like it's really going to increase the mileage and you'll have to stop and let some gas out every now and then. But in reality they take your money many times."
And Aaron says if you're not careful, some of these things can actually damage your car.
He says sticking to the basics of maintenance and upkeep really does ensure the very best fuel efficiency, and saves you money in the long run.
Aaron gives out something free to people all the time and it can actually save you more money than any of these gadgets.
Depending on your car it could be as much as $100 a month. Any idea what it is?
It's a ballpoint pen. Make a list of your errands before going out; that way you won't be driving all over the place and going out multiple times a day.
