And I think those people were wise in asking - the last engine build by navistar was very problematic so the 6.4 was quite cautiously received. Other than some recurring radiator issues and some early oiling issues to one of the turbos, I havent heard much besides the fuel mileage rants. However, I havent been paying all that much attention either.
Have any of you guys sat in one of the 2008 Superduty's or driven one - they are vastly improved and refined over previous models - the cab is along the lines of the newer F150 but one step nicer. The same holds true for the new Dmax as it makes the one like my brother's look dated.
I love mine the ride is nice. Its a mans truck. I really dont have any mileage issues with it. What do you expect its a 9000lb brick. If I wan't better than the 20 I am getting on the highway I would have bought something smaller.
Thats by far the best mileage reported so far - almost every owner I talk to is closer to 15!
There are some good deals on the 3/4 and 1 ton diesel trucks now - saw a 2007 full load King Ranch w/53000 kms - asking price around $45000. Some 2005 trucks priced at $30000 with low miles.
Are the guys you talk to calculating this or using the onboard MPG because they must remember that the onboard is US gals so the 15 l/100km is about 15mpg US or about 18 UK. If you keep the boost below 10 which is about 65mph the mileage on the highway is great. If you put your foot in it or drive around the city lots it drops in a hurry. I have not reset my onboard in a while and combined city /highway it is running at 16l/100km so that is about 17.5mpg UK. I am happy with it.
Truck prices always amaze me they seem to hold their value for a long time. Maybe fuel prices will drop truck prices.
Hey I just hit 500 posts.
I need to talk more to catch up to some guys.
my biggest beef is that the navistar engine puts a black mark on the blue oval name... sure any engine can and will have problems, no matter what the make, but the early 6.0 was purely a nasty kick in the pants for ford. the triton v8's and 10's are awesome engines with great reliability and longetivity...
It wasnt just the early 6 liters that put that nasty black mark on fords name either. The 6 liter was problematic in 05, and I personally have a few friends that have had the "typical" problems.
Even the trannies, I have know 2 05's that blew the torqshift out while towing, and 1 03 that blew out at least 2.
If ya read around in the 03-07 6 liter super duty forums, lots of guys are having problems stock, and have found ways to beef them up. They get pretty touchy in there too if a guy comes in and complains about some of the factory screw ups that navistar had. The suggestions are to always throw a pile of money at it if its not under warranty lol. Ah well, to each their own.
Just before I left for a week I was out snooping around the ford lot at the new 6.4 liters. I would love to get one, but still a little hesitant right now.
Duncan if your getting 20ish on the highway that is very respectable. Did you do any of the mods that some guys to to achieve that?
i've noticed quite a variance in mileage claims for the 6.4L diesel... some guys getting 20-22, others 9-13 sort of deal. really makes you wonder how the driving styles compare, or if there really can be that much difference in one such truck...
It is driving style. I drove to Edmonton and half way back and the lie o meter showed 13 l/100 km which is pretty good I was driving at about 100 km/hr , but when I hit Lloyd I put my foot in it and pushed it to 120 km/h the mileage dropped to 17l/100km as an average over the 1200km trip so you guys figer this out.
Its a 9000lb brick if you drive at 100km/h its great if you drive at 120m/kh it sucks.
no mods at all
I am just old
I know when I went to price out an 08 last year, the salesman told me that he knew a bunch of guys with them that were getting some crazy numbers for mileage, 28 mpg or something. I chuckled at him and told him I had a 7.3 and theres no way a brand new non broken in 6.4 would get better then my ol truck.
Once you get a crew cab you will never never ever never (get the point) go back. Entrance / exit from the rear seats is great - so it the ability to keep your drivers seat all the way back if you are a big guy with there still being ample room in the back seat. As well, the superior cab structure with the post just makes things move and creak less. At first I thought they didnt look as sporty as the supercabs (in both the ford and gm's) but now its the opposite for me!
