This device sounds too good to be true. It’s called the Blade and it screws onto the end of your tailpipe. Through extensive testing, it supposedly shows from 16-34% savings on gas! That’s an average of about 3.8 MPG’s. As an example, a US driver goes an average of about 30 miles per day or 10,800 miles per year. At the national average of 22 MPG that means about 490 gallons of gas. At $4, that’s roughly $2,000.

Apparently, when you add the BLADE to your tailpipe, you would only use about 418 gallons or about $1,675. Your savings would be roughly $325! Since I suck at math, I’m forced to take their word for it. The device costs $200, so you could make your money back in several months and still be saving after that. It saves gas, money and the environment. What more do you want?
