Just this morning (how very long ago), I wrote about the mental affects of a gas mileage computer in your car.
One of my frequent commentors, Samerwriter, commented that he uses a device that plugs into his car’s ODBII port and gives him real-time data about his gas mileage.
He has written a detailed, but personalized review of the product, called ScanGauge, at his site.
Now, the product is about $165, but if you have multiple vehicles, or just like gadgets and efficiency, you may be interested in the product. It’s a bit too pricey for me though. Since our Malibu is the only one of our 3 cars with the gas mileage readout, I’ll just stick with checking my MPGs at each refill.
