My 2007 Sprinter 2500 cargo has only a little over a thousand miles on it now and is getting an average of 13.5 mpg with the new diesel engine. Not quite what I was hoping to see. Granted most of my driving is in town and it is loaded as a service vehicle with shelving, parts, and tools. I went to this from my 2003 Dodge Ram which got all of 10.5 mpg on gasoline. I guess when the Dodge emblem goes on the fuel economy goes out. It is roomy though and great to work out of.
