I'm wondering just what engine gets the best fuel economy?
Currently I have a 2005 Volvo with the Volvo 12 for an engine. Getting very low fuel mileage like under 6 mpg. :thumbsdown: I am seriously thinking of trading off mid year. I have driven Freightliners with Detroits and have gotten mid 6's for mpg. My main loads are paper and are in the 40,000 plus range in the mid to eastern part of the county.
I am interested in what others are getting with Cummins which is the other engine offered by Volvo along with a few other truck manufactures. Any good advice?
