Let’s hear your best MPG and driving style ?

..... back on the forum with a new rig .....

[dodge_guy]

I average 5.6 towing my 13 Explorer with 4 bikes with our 12 Georgetown with the V-10 and 5 speed auto at 70mph. slowing down to 65 doesn`t seem to change the mileage any. without the Explorer I`m around 6.5. GCW at 26,300lbs.

Cat said that the best MPG is achieved when you are running at the RPM WHERE THE HIGHEST TORQUE IS ACHIEVED. We ran a 100 PRM above that suggestion. For us that was ~60mpg! We found lower elevations resulted in higher MPG. When the sulfur content of the fuel was reducing we lost ~0.3 to 0.5 mpg. We log all fuel mileage. We also set Tire pressure per the tire manufacturers recommendation based on 4 corner weights. We ran a TPMS to monitor tire pressure. We rarely utilized full acceleration starts.

Damon Intruder (2005) 377W Workhorse. 8.1L vortec 100 MPH tail wind I mean dead astern tumbleweeds going straight down the freeway 13.8 MPG

[Ro_n_Joe]

7.25mpg going 65-66 while using cruise control. Cruise control works quite well on our rig. I also keep the jake brake off.

I was going across The Bonneville Salt Flats on I 80 one time. It is very flat and there was no wind that morning. About 50 miles of flat, straight road.

I experimented with going 65 MPH for five miles and then 55 MPH for five miles. And then 65 MPH for five miles and then 55 MPH for five miles again.

My instantaneous MPG readout stayed pretty much the same for both speeds so I'm in the camp that says it doesn't make that much difference.

I've averaged 7.1 MPG over 95,000 miles. I recorded ever gallon of gas I put in the RV over the past 14 years. I don't care what it costs and will go to the gas station that is empty as opposed to going in the cheap places where I stand a chance of being hit by some nimrod.

Back in the old days, folks tracked fuel mileage as a method to monitor the health of their engines and as a means to detect problems early on. With the advent of computer monitoring systems in all engines these days that is no longer necessary. I know nobody who has a motorhome or large modern RV who would would ever make a trip go/no go decision based on fuel mileage.

Since most of us have no intention of making our travel plans around fuel mileage and the fact that it is no longer necessary for maintenance purposes, most of us simply don't bother or care what our mileage is.

Regarding shopping for price, I doubt very many folks do that to any great extent. I'm more likely to use the stations that appears the easiest to get in and out than I am to use the one with the cheapest price.

The fact of the matter is that, other than for bragging purposes, fuel mileage just doesn't matter. By the way, I get half a tank between fill ups. That's about as accurate as I can get. 😉

Interesting observations by some ! ..... who simply seem to not care about fuel mileage. Did you care about the price of your motor home? In your travels ... you wouldn’t “shop” for fuel ? I could go on ...... but the bottom line is - it’s your money - do with it as you please !

[way2roll]

Had a person approach me at a gas station while I was fueling up our previous MH and asked me what kind of mileage I got. I said, "It gets great mileage for an apartment."

I have never tracked fuel mileage because it's a moot point. I consider it part of the cost of Rvv'ing. I fill up when I need fuel.

[Sandia_Man]

Actually, I wouldn't know, whether car, truck, or when RVing, just never felt the need to track mpg. All our vehicles including motorhome have mpg tracking feature along with the couple of scangauge 2 modules mounted in our HD truck and class A. While I monitor other pertinent powertrain parameters, unless I see a significant change in fuel demand it is rare indeed for me to consider mpg, just pull up to the pump and open my wallet. Driving habits are typical, when RVing I stay within 5mph of posted speed limit, with daily driving I roll at 5 mph above speed limit.

'20 F350 6.7, 35' fifth wheel. 13 MPG in Indiana, 9.6 MPG bucking a big headwind in Texas. Averaged 11.5 over 7500 or so miles at 65-68 MPH.

[hedgehopper]

With our Dodge dually diesel carrying our Northern Lite 10-2 CD, we get about 15 mpg driving 55-60 mph.

[ferndaleflyer]

I get 9.25 to 9.50 with my 8.3 Cummins towing a Featherlite trailer with a car on it driving 65--70 MPH. That was averaged over a 1500mi round trip mostly on I-95

[RLS7201]

2013 Honda CRV. KC, MO to Hutchison, KS., 65-75 MPH, 35.6 MPG. Return trip, 30.4 MPG. Ah yes the wind does blow in Kansas.

I drive it like I stole it with our 40' 5.9 Cummins, hit 75 and 78mph and got 9.3 mpg pushing a small house down the road. My 5.4 Ford pick up gets 13 mpg driving it the same way, tho it lacks a bathroom, kitchen, queen bed, water heater, 90 gallons of water, a furnace, couple of tv's and a fully stocked refrigerator and bar.
It's all about perspective and what you're willing to put up with and or settle with. We're all different, and it's ok! Get out and enjoy yourself!

LandYacht35diesel,

Congratulations.

In my E-450 (gas) I get about 12.5 mpg if I drive at 48 mph. If I drive 50 mph that drops to 10 mpg.
