Fuel saving technology may prove to be the next big trend – though some of the products which claim to enhance fuel efficiency aren’t quite living up to expectations, at least according to the Wall Street Journal. There are products which claim to be able to be able to turn your car into a "water hybrid," and other which can supposedly improve fuel combustion – and then there’s the Scan Gauge 2. It can fit just about anywhere in the front of your car, works on vehicles made in 1996 or later (and in some ‘94-5 models), and keeps you up to date on fuel economy readouts from minute to minute. Some users say that they’ve gotten more miles to the gallon since using it, and are saving more than a hundred dollars a month.
