Re: What kind of milleage do you get?

Last trip out I got a whopping 4.76 mpg. Then I went to do a tuneup and found some issues in the distributor, as well as a base timing of 6 degrees advance (definately not right for a propane fueled engine). I will see what happens next time out, I am hoping for 7-8 mpg, but that might be wishful thinking.

Re: What kind of milleage do you get?

My last trip from southern Indiana to northern Iowa we made 13.1 mpg. When we went south to Hunting Island, SC the mountains knocked us down to 11.8mpg. Early this month we went from here to Gettysburg and though I didn't calculate mileage the mountains in the northern Appalachians and Allegheneys kicked our butts a little more. Still above 10 though because I didn't buy enough fuel to have gotten worse than 10. Looking forward to another flat trip to Iowa next month though!

Re: What kind of milleage do you get?

Hey All-
I'm contemplating buying a diesel bus with the 7.8L Brazilian. It's mated to a 5 spd. with a split axle.
Anyone out there have an idea of what kind of mileage it would get? Gracias.

My Dad says that North Dakota is the state where you can see the farthest and see the least of any state in the nation!

Re: What kind of milleage do you get?

I have a 86 flatnose blue bird. Bought it in Alabama in March. Got 10.5mpg rolling about 65mph. I use it to haul my drag car around and it is getting about 9.5 but that is because 70% of my trip to the local track is city driving...

I think it has a 5:13ish gear in it. I would like at some point to go to a 4:10 or 4:30 gear, a little more speed and better milage, I hope.

Re: What kind of milleage do you get?

We just bought a 92 Blue Bird All American RE 8.3 cummins / allison 643 with 4.78 gears.

Picked it up in Northern Oregon, drove 95% secondary highways back to Northern Arizona.

Average 55 mph and 11 mpg, bus was empty.

I'm hoping 9-10 mpg once the conversion is done.

Maybe changing the gearing to 4.11 would help a bit.

Re: What kind of milleage do you get?

Just bought myself a second bus, its an '82 International 71 passenger BB with air brakes. Picked it up in Denver and drove it 720 miles home. It has a Dt466 engine with a Mt643 Allison and 4.78 rear axle ratio. The engine, transmission and rear axle were all rebuilt five years ago and has less than 50k miles since the rebuild. Cruised home between 60 and 65 mph and got 9.5 miles per gallon.

I bought it because it has a eddy current drive shaft retarder on it that was installed new 14k miles ago. I've always wanted one of those. Just the retarder cost between 7k and $10k itself, and I got the the whole bus for 2300. Love it.

Re: What kind of milleage do you get?

I have a flat nose front engine Blue Bird. It has the 1160 CAT diesel (precursor to the 320. The tag on my dashboard says 6.8 rear end. I think that the rear end may have been changed before I bought it, because I drove it pedal to the metal on my trip from Nashville to Springfield Mo. and the bus went 67 MPH.

I think there must be a governor on the motor. I use a GPS to tell me the speed. On my trip from Nashville I got 8 MPG. My bus weighs 22,000 lbs.

Recently I went on a 130 mile trip, and it was weird that I was able to go 69 to 72 MPH on that trip. I figure that I am still getting 8 MPG.

I do not have a tachometer.

Can anyone tell me why I can go so fast without blowing up the motor? If indeed the rear end is 6.8, I would think that the governed motor would not let the bus go that fast.
