A mechanic also tested it &amp; said he saves about 22 miles per tank. You plug it into your cigaretter lighter. I bought one with shipping for $38. We will see how it works when we get it. If it works I guess it will be worth the money to save the price of a gallon of gas each time you fill up with gas prices close to $4 per gal.</P> Wed, 18 May 2011 01:17:43 GMT Nightowlz 2011-05-18T01:17:43Z https://community.qvc.com/t5/Community-Chat/Fuel-Shark/m-p/79928#M43298 <P>Anyone have one of these?
