This MPG display lets you dynamically improve driving. See how mileage changes as you accelerate, climb and descend hills, or cruise the highway. Fine-tune your driving. Reduce bad habits, use less gas.

For this ScanGauge II review, setup was simple, no wiring or batteries needed: Plug it in, and start your car.

The mileage monitor isn't ScanGauge's only tool. It's also an OBD-II code reader, allowing you to read and clear problems caused by "Check Engine" lights. Report trip info, like overall mileage, average speed, driving distance and fuel used.

After using the ScanGauge II in my 2002 Saturn SL, here's what I learned:

During acceleration, letting up on the pedal just one inch increases mileage by 15 MPG. Turning on air conditioning drops mileage by 4 MPG. I always thought coasting in neutral improved mileage (versus leaving the car in gear), but the ScanGauge tells me it makes no difference. Cruise control is usually good, but wastes too much gas on hills.

The ScanGauge II comes with geek-friendly features: It's upgradeable, so future improvements (like PC communications) can be installed. Car hackers can send OBD-II commands to their cars' computers, tweaking to improve performance. Customize many options (including the screen backlight, with 63 different color choices).

At $159.95, it's not cheap. But learn from it, and it does pay for itself: I recorded mileage before and after buying my ScanGauge. In city driving, using it to adjust my driving habits, I averaged 15 MPG before the ScanGauge and 19 MPG after. I fill my tank about once every ten days. Assuming gasoline is $4 per gallon, I'll need right at three months to save $159.95 in gas.

"In times like these, with horrible gas prices, the ScanGauge can help you save gas money by adjusting your driving habits."
