With gas prices climbing higher and higher, it's ever-more important for everyone (individuals and companies) to get the most bang for their buck -- in other words, to get the best gas mileage from their vehicles.

Want a simple way to do that? Try installing the ScanGuage II from Linear Logic. This tiny device plugs into the onboard diagnostic connector in almost any car or truck and instantly starts calculating all kinds of critical data -- including your exact gas mileage. Knowing your MPG at any point in your trip allows you to adapt your driving methods to improve your overall efficiency. Bingo, you'll be using less gas, saving money, and putting fewer greenhouse gases into the atmosphere.

ScanGuage II also tracks a lot of other cool information, such as how much fuel you have used and how much time you have been driving. It's only five inches across, making it easy to install just about anywhere in your vehicle.

I first saw tools like this in the dashboards of hybrid cars, but this is the first time I have seen an equivalent device that can be used in any car or truck at any time. ScanGuage costs just $169.95 (including shipping) -- a bargain at half the price if it teaches you to improve your fuel economy and reduce the number of trips you need to take to the pump.
