Gas mileage report

[Snowman9000]

When paying $1.69, it doesn't matter as much, but I have gotten a handle on our 25' Chevy 4500 Class C's mpg habits.

60-65MPH, neutral conditions: 10 MPG
tail wind: 11 MPG
head or strong cross wind: 8.5-9

Mostly with cruise control ON. No toad.

On 5,000 miles if you can go from 8 to 10 mpg you can save a whopping $400 at 3.50 a gal (more than current prices).

Not worth the hassle to worry about considering all the other costs.

Maybe not to you, but I'm quite sure most of us would rather have that $400. in our pockets than in those of the oil outlaws.

Granted, but 5k miles at 65mph is 77 hours and 5k miles at 55mph is 91 hours, a difference of 14 hours. That's 2 days of driving 7 hours per day, or $200 a day.

Given the choice of spending an extra 2 days on the road, or 2 days on the beach, there's not much much to discuss.

Now that it's under $2 / gallon, it's even more moot.

Actually for me 14 hours is 3 days, but to average 65 you have to do what.....75+ as your going to need to stop more often for gas and the cop....hehe.

That's why I said "driving for 7 hours per day".

If you make stops for fuel, meals, or anything else that would be over and above the 7 hours of driving.

My rig is a '93 Class A with a 7.4 engine with overdrive transmission. Under normal flat land driving we get 8-9 MPG towing our 4000 Suzuki. Yes, we drop down going through the mountains and in stop and go traffic. Our rig and toad total weight is right at 19,000. We keep a log of mileage and expenses, so our mileage should be pretty accurate.
I would think that a 6.0 engine would get better mileage.

That isn't very good mileage.
I would start by slowing down almost 10 miles per hour.
I am guessing this is a 6.0 gas engine.
Chevy 4500? is this like a Kodiak chassis? That would make it more like a Super C.

That is excellent, honest, real world mileage. My E350 V-10 averages 9.5 (over the last 21,000 miles), cruising 60-62. Sprinters that allegedly get 21 mpg... not so much.

:S

In the interest of full disclosure... I just realized that the computer has a running total of gallons used, and I have never reset it. So the math works out to 9.4 MPG over 7800 miles. I'm a little disappointed that is was not roughly 10, but it does seem I'm always driving into a headwind! 🙂

Keep it at a steady 55 with the V-10 and watch your MPG grow in leaps and bounds.

Got my Ford E450(6.8L V-10), beat, I see 8-9.5 with varying conditions.

Me too. This cheaper gas is great but how long will it last?

It will last as long as it takes for domestic oil production to be shut down. Understand OPEC production sets the price of crude not big oil. The current price for crude is below what it takes to produce domestically.

We have the old chev 5.7 in a 21' rig. It is consistant with 10.8. I just
drive the speed limit even if it's 70 mph.

[Snowman9000]

Like Gene in NE, when we had a lower, smaller, more aero Chevy B+, we were looking at 11-12. That was nice. But we have MUCH more room now, and I'm content with 10 MPG.

Chevy vs Ford 😉

We get 8.9 ave: Ford E450, 26ft B+, 60lb front, 70lb rear, recent alignment, synthetic oil, 55 to 60 mph, feather foot, no toad.

I believe that regular (no ethenol) gas would improve mileage by about 10%. My previous Chev (3500 series chassis) unit did about 5% better than my current Ford based unit.

Its weight, rolling resistance, gear ratio, speed, aerodynamics, fuel type, weather, terrain, and power.

Wish they had a hybrid motorhome that could use sun power to improve mpg by 10 to 20%. Just paint the whole thing in solar panels.

I would be doing my happy dance if we got 10mpg. Snowman9000..think you have a good unit. Nice choice of size, features, and fuel economy.

We have almost the same 25 ft RV but with chevy 3500. Our gas mileage is the same as the OP but our is at 55 max speed. I doubt going 10 mph slower would do that.

That's exactly what ours gets in the same conditions.
