Ahhh...
Actually its kinda the opposite problem its geard right so it shoots to 50 pretty quick but 60mph is a struggle b/c ts at 3200 rpm with OD off and if I turn the Od on it just bounces on an off of it and thats not good for the trans 70mph straiht and true down the interstate is fine though.
some friends of my family's all drive new duramaxes, and this year all 4 boys (1 dad and 3 sons) admitted to paying over $15000 in fuel EACH. NO TYPO. thats how you know you have too much ,money.
id agree, these new diesels out now adays with the DPF get HORRIBLE fuel milage, specially when there brand new and dont have any miles on them. i drove my company truck,, 08' ford f350 powerstroke 6.4 from indianapolis to tuscan, arizonia and averaged 6.5 mpg pulling a tandem axle inclosed with about 8k pounds in it.. the emissions crap is killing the new diesels fuel milage. in my 04; chevy duramax i get between 18-22 mpg
Ever brake the tierods or axle shafts on that while pulling the sleds? Chevys and GMCs are infomaus for blowing out the front ends while pulling sleds.heres my tow rig..all 532hp and 1025ft lbs of it!!
The lack of desire from the manufacturer to develop better engines is killing mileage. My one work truck, powered with a Volvo D13, is a 485 hp 6 cyl diesel and it gets that mileage pulling at 107k pounds total. Why can Volvo get that mileage while our Macks get 4 or so with the same Eaton-Fuller 10 spd?
Different emissions standards. In their defence, I have never heard of a Powerstroke get THAT bad of milage. It is usually about twice that, which isn't all that great either.
yes, they will break if you dont inforce them, $90 set of sleeves fixes the tierod breaking problems and lowering the torsion bars will prevent the half shafts from breaking, but i rarely see halfshafts break, only on lifted trucks with a lot of angle on there shafts. alot of the guys dont know what there doin and built up there truck and forget about the front end, yes, IFS sucks but it doesnt take much to bulletproof them..
The 2010 HD truck standards are very strict. Not much different than those on diesel light-duty trucks.
Like I alluded to before, that isn't typical milage for a 6.4 anyway. They usually get at least twice that.
