Volvo 780 with a Volvo d13 engine (425hp) 13 speed. Dont remember the rears but it was a weird one like 342?? Have to check paper work it' not on the door data plate.
What kind of fuel mileage do you get? What rpm and speed is best for max fuel mileage? Im only getting high 5 and 6's.
Havent had this low mileage since the 80's. My last truck w/Detroit got 6-8. One before that had a Cummins and got 6.5-7mpg.
I'e tried everything i no and have ever heard of. But just can' get this mileage up.
Whats your experiance?

I have a 770 but with an N14, 13 spd and 3.42 rears on low pro 22.5 and consistently get low to high 7's

I try to keep my foot out of it around 68-72. But you no now us movers are. -
7-8 mpg during winter, 8-9 above freazing, running 62mph with average and light, 55-60 very heavy ; i sold it with 1,833,000 miles on original motor,D13/08.
I just purchased, used same 780 ,2010 ,D13,Eaton 13 i get same mpg.
You are too fast for good mpg, especially this time of the year. I purchased it new in June 07, imo not perfect but still an exceptional motor, plenty of power,torque and great on fuel.Attached Files:

I am always light so according to you run 62mph? Not gonna happen. But thanks for the advise. Been driving the way I drive since 1973? Alwas been able to get decent mileage out if every truck I've driven. Cat, cummins, detroit, mack, international. Don' no what' up with volvo's? So wanting to no what speed, rpm, and mpg everyone else getting. Have a friend with same engine. She gets 8.5 all the time, but she has an automatic.

Volvo's cost so much to repair the savings in fuel is voided as soon as you end up in the shop.
