I am looking to buy a 2000 E350 Collins bus with the 7.3 L in it. I just sold my 95 7.3L and am wondering what the gas mileage comparison would be.

Im buying it to go on a 7,000 mile road trip, then possibly using it for a party bus service afterwards.

 

You're pushing a lot of air around with its frontal area.

I wouldn't expect more than maybe eleven, if that.
