The Gaslock Indy Cator could not have come at a better time as fuel prices around the world are soaring faster than an eagle taking flight. This device features a radical design and some pretty nifty features that enhances the entire driving experience. The energy-saving function informs you exactly when would be the right time to shift and save gas. The manufacturer claims that you can spend up to 15% less on fuel if you follow its shift timing correctly, but I fear your concentration would no longer be on the road anymore. The Gaslock Indy Cator retails for $169 and obviously does not support vehicles with automatic transmission.
