Survey Time! - MPG of Your Bus??
« on: February 16, 2022, 05:28:20 PM »
Survey Time!  ;)

What's the average fuel mileage you are getting out of your bus?

Please put the year, make, model, engine, and transmission type of your bus too.

Thank you, guys!!

My little 10,000 pound bus with the 5.2l Isuzu turbo diesel averages 15 mpg.  A little less with the toad and a little more without.

I know, I know---Damit Jackie shut up!  But look at all the fun we have in it.

6V92 with Allison HT 740. Last trip if I did the math right was high 8 per gallon, but it was from 2000 feet up where I live in N Georgia to Lakeland Florida. All down hill or flat. I don't tow. And Ok...maybe a tailwind.
When 20 of us have answered, Sandra is going to come back on and tell us that even though she is full time, they had to buy fuel for her skoolie ( and nice bus by the way) back in November....
