RV Fuel Issues & Prices - Post 'Em Here!

A scan gauge ii (I have one) reads information from your vehicles computer and displays it. You can pick four measurements. Current MPG is one of the measurements. The only problem is that it is not terribly accurate and needs to be "adjusted". There is a procedure where you reset the fuel used, then drive until you need to refuel. You record how much fuel was actually used and the scan gauge calculates a percentage adjustment that it applies from then on. Mine is 14% (my actual MPG is 14% less that reported). It works well after that.

Since y'all are not search engine equipped, I have included a link for you to get the basics. It has 15 plus gauges that tell you the internals of what is going on in your engine. Most of these are not included on your instrument cluster. As far as being part of the 60's, it utilizes the federally mandated 1996 trouble codes and has been updated regularly.

ScanGaugeII can help you monitor your vehicle’s most vital systems and provide the kind of real-time information you’ve been missing. Features include more than 15 built-in digital gauges, 5 sets of trip data and an easy-to-use ScanTool that shows both set and pending trouble codes

I need to warn Fizzwig that the article contains some big words, but will be helpful to those wanting to get better fuel mileage.

Does "ScanGuage" do more than the manifold vacuum guages we used back in the 50s?

Why did people stop using vacuum guages? I haven't seen one in years.

Scan guage is kinda a throw back to the 80's.
Most all newer rigs and TVs have all the info you get from them and more plus normally an audeo and visual info notice in the instrument cluster.
In my world GM isn't going to let you not miss anything important to the diesel or the trans. because they are the ones guarenteeing them for 100,000 miles LOL

This morning some stations are down to $3.74 for regular gasoline. Diesel was $4.15 for bio-diesel, $4.39 for the rest of the reporting stations except one at $4.52. Again, glad we didn't upgrade our motor home a few years ago to a DP.

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.

GRRRR We had the same******here this week. Gas has gone from 3.89 to 3.49. Yesterday diesel jumped overnight from 3.93 to 4.29. I can't find any reports on why diesel has jumped while gas goes down.

$4.18 gal wed night in Amarillo Tx at Loves for B-15
one place i passed on I-40 was $4.52
but most were $4.18>$4.33

gas was really cheap 3.55 might be E-10 i didn't bother to check the gas pump

Wow that CNG fueling station in a box is exciting. It will deliver a 40% savings over $3.50/gal and we have centuries of supply. I don't see why this couldn't be used on RV's. The 7+ gallons per minute delivery of fuel is acceptable. That would have saved me hundreds of dollars in the last few weeks. I understand that regular gasoline engines can be converted to GNG, but I would think it would generally be on new coaches and trucks.

GE and Chesapeake Energy announced yesterday that they are launching their CNG in a Box (tm) system, for faster development of CNG infrastructure. The compression station is in a 8 x 20 foot container for easy set-up and connection to gas pipelines.

Take a look here and here.
