Gas Mileage

My Dad just called me about a device you can put on your car to increase gas mileage. It is a two step process. The first step is 100% guaranteed to increase your gas mileage by at least 50%. The second step is totally optional. Also sounds like the second step won't be available for several months. After the second step is installed, which is a pre-ignition catalytic converter that installs in the same place as your old CC, it looks like most cars will get over 100 MPG! Here's the website www.preignitioncc.com/northstar If anybody checks it out I'd like to hear what you think of it. I watched the video. They had a Briggs running on 60% gas and 40% water. The video is about 20 minutes long but I thought it was interesting. Dad called the number in the ad and a guy in Bismarck is the dealer. He has his own mechanic that installs them and tunes your engine. He told Dad if you drive 15000 miles a year you can pay for it in a year. Probably sooner if gas hits $4.00-$5.00 this coming summer as some people are predicting. Gas in Strasburg today: 10% Ethanol $3.19 Regular unleaded $3.29.
