RV Fuel Issues & Prices - Post 'Em Here!

During our recent month long trip (got back yesterday), I used a new fuel saving tool, ScanGaugeII. It is a engine trouble light system that also has a gauge with about 25 engine system gauge readouts that are not normally found on a motor home. One of the gauges is instantaneous fuel readout in MPG. My engine has one below the odometer, but it is very crude. This one updates every couple of seconds. It is amazing how little changes in accelerator pressure and road conditions can make a large difference in mileage. Speed is very critical also. Great for hills and mountains also. I found that I was able to find a "sweet spot" for most driving conditions and felt sure I increased my mileage drastically. I had another stray trouble light before the trip and decided to buy the gauge which was about the same as a trip to the shop to find out what it was. It hooks into your trouble light socket found on all US sold vehicles since 1998. It is basically free if you have a engine trouble light come on. I Velcro it to the dash and also use it on my truck. It senses which vehicle is being used. A great way to save fuel.
