Mileage is ugly for sure when doing Red Mountain from Ouray to Silverton.

Be SAFE!

When I did it, driving "UP' the mountain and navigating the turns wasn't bad. It was the coming "DOWN" that bothered me. LOWER gear for sure! But, I still used the brakes and they really heated up and start smelling. I pulled off two times to let them cool down; and then travelled on. We were towing a 2008 Jeep Liberty.

I assume you don't have many miles on your brake pads, or you haven't done many mountain decensions to use/ride your brakes. If so, you may want to check the brake pads.
Happy and Safe travelling to you!

I have an 08 378XL towing a Jeep Cherokee I get 7.5 to 8 mpg, of course that's all down hill with the wind in my back and my wife pushing for good measure. All in all if you get 7 to 8 you are doing the same as everyone else.
Remeber these are not our evey day driver's.

Filled up for the second time today. 7.16mpg this time. Better then that 3.5 of last time. No idea what happened that first time.

Maybe the locking gas cap was the key?

350DS has a 75gal tank. With the gauge indicating 1/2 tank I put in 46.738 gallons. I guess that the gauge isn't right on eh?

The Locking Gas Cap was one of the first things I bought once we got the coach home. I'd didn't want to become the filling station for anyone out there looking for free gas.
Gas gauge is pretty close but I don't believe any are exact. Ever notice how long it takes to come off "FULL" but then how quickly it drops after it reads "1/2" ?

1) Fuel gauges are electronic sending units that rely on mechanical systems to provide the information they send.

2) Fuel tanks are not symmetrical but are shaped to fit in the assigned space.

3) It is not possible for a mechanical arm with a float on the end to travel from the top of a weirdly shaped tank to the bottom and register the same amount of fuel through it's entire range of motion.

4) The attached photo is a custom shaped F-350 gas tank. Picture an arm inside going up and down as you use fuel. Since there needs to be room for the arm to reach the bottom, the float will stop its upward movement well before the tank is full and will be submerged until the fuel drops low enough to start indicating. (Gauge reads "full" for a LONG time)

5) Depending on the shape of YOUR tank, it might take several gallons to even show you used any gas. Then drop quickly, hang out there a while and run on "empty" forever.

6) Electronic DIC (driver information center) computer systems do not care about what is in your tank. They monitor your ENGINE and display fuel USED as you drive. If you have a 36 gallon tank you can watch every drop leave regardless of its shape. The DIC in my GMC Sierra is right dead on and at places where I have to pre-pay for diesel I look at the DIC; multiply by the price per gallon and have never missed my pre-pay.

Our first trip in the 2011 360 gave us 7.5 mpg. That is about normal.

I wish the ford gave this kind of information. Aside from the gauges I get odometer, one trip meter and engine hours. That's it.

How often was the generator running on the first trip? 7-8 mpg is about right for a Ford V-10 hauling a load.

A good mileage tool that I use for our cars is Fuelly | Share and Compare Your MPG

Most of you are getting better than me. I get around 6.5mpg towing a car (25,500#s), and a little over 7mpg if I dont.
