ScanGaugeII
If you've read the ecomiling lessons, you might have noticed that I frequently refer to a device called the ScanGaugeII. Although it's true that you don't need to spend a single cent in order to reap the rewards offered by ecomiling, a device like the ScanGaugeII is well worth its price. The information you get out of the ScanGaugeII will help you perfect your ecomiling technique, custom tailor your driving style to your car in order to maximize your fuel economy and will further allow you to take advantage of the advanced techniques presented in Lesson 8, which in turn will allow you to further improve your fuel economy.
Suffice it to say, the ScanGauge II will pay for itself at the pump many times over, and probably in just a few months for most drivers. If your car's gauge cluster doesn't provide you with instantaneous and trip fuel economy, the ScanGaugeII is a worthy investment and I highly recommend that you consider buying one. I love mine!
The ScanGaugeII plugs into your OBDII port, which most vehicles made since 1996 have, and allows for immediate, toolless and completely reversible access to your vehicle's computer. Anybody can install the ScanGaugeII and everything you need is included. No batteries, no optional accessories and no leg work. Just plug it in and turn on your car.
You get a compact, highly customizable device that allows you to scan, test and reset your vehicle's error codes, provides you with a host of real-time gauges including but not limited to fuel consumption and economy, and has four sets of trip data to track all sorts of vital statistics, once again including but not limited to fuel consumption and economy.
I am in no way affiliated with the manufacturer of the ScanGaugeII and I do not profit in any way, shape or form from this recommendation. I just appreciate the difference the ScanGaugeII has made in my driving and I believe that anybody who intends to practice ecomiling would benefit by installing one.

Disclaimer: It is of critical importance that you always place safety first and fuel economy a very distant second. Although ecomiling may be an engaging, exciting and money-saving challenge, never place fuel economy above your safety or that of other road users. Obey all local traffic laws.
