How many miles per gallon does your bus get?

As Cummins post on their site "fuel makes horse power and horse power is used to overcome the forces" simple and I agree

My bus is a MC-6 weighing in at 45,000lb. power is 8v92 with HT740 transmission. It seems like it gets extremely good mileage at 4,560 miles per tank. Then when I finally fill the tank... I darn near break the bank at $3,496 that's $1.31 a mile! (4.60 per gal up here)
Do the math... I can't afford a calculator lol!

And I love using my fuel to overcome everything in my path while driving this Cummins

Chessie you have 1 bus to many, and I just happen to be looking for 1 lol

1981 Prevost with Cummins M11 and Allison 740 trans. It has averaged just over 9 mpg since we started using it. It is geared for 1600 rpm's at 65 mph. We normally cruse between 65 and 70. Bus is not that heavy it weighs 30,000 lbs loaded.

I can image carrying about an 800 gallon fuel tank.

David G / Morefire, I am wondering about the weight of your Wonderlodge 40' and what transmission you are using that would take the hp and torque of the ISX in the 675 hp mode ? Know the ISX isvery capable of much more HP & Torque, so am courious why stop at 675 hp etc.?
Thanks

40ft AMGeneral transit with 8V-71TATAIC and V730 with 4.56 rears, 11R-24.5 rubber. I cruise at 60mph at 1900rpm. Just the bus, I get 6.4 without the gen on, 5.8 with the gen and A/C on. Towing my 3750lb Mercedes 300 Turbodiesel, I get 5.2 without the gen on, 4.8 with the gen and A/C on.

I'm anticipating getting 7-8mpg with my truck conversion. Doesn't sound like much, but 4.8 to 7 is 46% better fuel mileage! Good luck, TomC

Here is the weight slip for my coach, full of fuel and water.

As for the Engine/Trans combo, My ISX is a factory OEM 600HP model which I was told by Cummins has different pistons, injectors, bearings etc.... than a regular 435-500hp version. And because of this, the Programmer Company that I used to modify my ECM and remove the DPF and EGR from the system said he could program my engine to produce 1000HP or more, and in my application it would be safe for what I do without any other engine mods, ..........the problem was the Transmission.

It is/was an Allison B500, when I called Allison and ran the serial number, they said it was only good for 500hp max with its current B500 setting. But they told me my transmission was physically the exact same transmission as the MH4000 model, which is capable of up to 650HP. So I had my B500 Computer flashed and Reprogrammed to convert it to an MH4000 to handle my engine....
The Tech at Allison told me if I wanted to use more than 650HP, internal parts would have to be modded to the Trans, but didn't go into details about that and I didnt want anymore down time trying to have that done.

With the transmission information, I then had the engine programmer install the OEM Cummins 650HP setting (which Newell uses).
They told me that by Removing the DPF and EGR from this engine and using the 650 setting, the engine would develop about 700HP and 2085LBS Torque as it is right now. And I can tell you, it's a real monster. It cruises at 65MPH @ 1350RPM effortlessly, holds it's speed on cruise control and doesn't change gears on hills, unless we are talking about mountains

Most people have a fixed income do you thhink we just go out and print money when we need it. If you don't have enough income get another job. My wife works for a doctor and they come in and say I am on a fixed income and can't pay my bill, or give me a discount, but they drive up in a BMW, smoking, holding a Dunkin donuts coffee and probably drink up a storm when they get home. But they are on a fix income. BS.

sledhead · March 14, 2013, 05:42:43 AM

On our last trip 4000 miles not in the hills 6.7 mpg yet in the hills 7.3 to 7.5 ? This was the same southbound and northbound . When on the flats i use cruisecontrol at 70 or 65 as at least the speed limit. I can't understand why i get more mpg in the hills then on the flats? 1990 mc1 102c3 38000#with a 3600# truck in tow 6v92ta ht740 333 rear end 315 80 22.5 tires dave

garhawk · March 14, 2013, 07:23:58 AM

Eagle Model 20 w/series 60

Right now it's 7.3 gallons diesel every mile or, maybe thats 7.3 fillups per hundred miles - I don't know. When you wife is screaming slow down and you're trying to get to the next truck stop before the price goes up, its hard to keep up with such trivial minutia.

Anyway, Ken (hardheaded) is gonna redo my bus's computer so it will tell my engine to use less - maybe even get close to that Miracle Eagle up in Shysterville, SC.

Hard Headed Ken · March 14, 2013, 08:19:03 AM

That's what I wanna know.

Where's ERIC?

Well scandel thanks for the friendly advise....lol Just for your information I am on disability and live on about a thousand dollars a month. I have lost part of my right foot due to 40years of diabetes, was in a coma for 3 months due to pnemona , had a quad heart bypass, so After having my own contracting business and working 6 to 7 days a week now I can't just get another job. I do have a older Bmw, a truck, harley, and 3 houses that are paid for, but no cas in the bank, so yes I am on a fixed income, Ok guess I now have 2 people ignoring me....lol

Whoa, wait a second here. Y'all this does not need to slip to this. An old saying I heard once said, "An undeserved curse will not bother anyone."

Scott, please take your rant private or elsewhere. In my book totally uncalled for, when you were asking for help. If you weren't looking for a fight, and had an open mind, you might possibly be able to figure something out. All kinds of computer work these days, if one has a mind to learn. I think Scanzel's point is, nobody has as much as they would like. However, if more is needed, then there are ways to get more.

Mods, can we please trim this out before it gets out of control?

Cheers,

John
