Some of yall need to take you trucks to Greensboro Volvo HQ because according to them they haven't built a truck that get in the mid 7 mpg range. I been fighting with them for the past year or so about my fuel mileage I was getting 6.8 pulling 43.5K and that grossed out Had an injector go out and take out a rocker arm they replace the injector rocker arm and all the springs ran an overhead and fuel dropped to around 5.5 I have had 2 more injectors replaced since and each time overhead was ran and still not seeing anything north of 6.4 and that running light I do run the speed limit most of the time + or - but with a heavy load and a light foot 5.8 is about the best. Now empty I can get around 7.8 and close to 9 bobtail. And of course a lot of this depend on terrain

They need to talk to their big customers. Because mine is an ex-Interstate I try and talk to any and all of these guys to get any information I can how the company works. When they see the MPG charts, the Volvos without automatics are getting 6.8-7.5. They look if someone drops below 6.8 at loads and location. If it stays below they bring it in to check what is causing it.
