Opinions Wanted on 6.4 Liter Twin Turbo

I'm looking at a low mileage, 2010 Ford F250, 4x4, crew cab pickup with the 6.4 liter twin turbo engine. I'm sure the diesel will be great for pulling trailers (which I do) but with high fuel prices and some maintenance concerns I'm a little aprehensive about a diesel for a daily driver. Like with anything, I've read a range of opinions about the 6.4 liter TT.

I'd appreciate your feedback on the 6.4 liter TT engine. I know Ford has changed manufacturer's. Are there specific problems or maintenance concerns (related to the 6.4) I should be aware of? Have there been any recalls or TSBs to know about? What type of gas mileage could I expect? I'm just looking for general feedback to better help me make my purchase decision. I value your time, experience and expertise....thanks!

6.4 is an excellent hwy or towing motor. Not so great for a commuter, unless it is hwy or long distance.

Most issues center around the emissions and the radiators.

Since you are looking at a 2010 I don't think the radiator is the concern for you. Emissions takes some getting used to. This is what has turned this into more of a long haul motor and less of a stop and go city truck.

In order for the emissions to work best it needs heat and a long duty cycle.

So how is your commute? You say you tow..how much and how often?

This won't be a daily driver per se...it will see some day to day use but I have other vehicles I can use to go to the store, etc. I pull a heavy steel 3-horse slant trailer on occasion but more regularly I pull a single, tilt-bed auto trailer (hauling a track car)...about a couple weekends a month. My present 3/4 ton, 4WD Suburban with the 8.1 liter gas V8 works great but it has over 176,000 miles on it. I'd rather have overkill for towing. I realize the 6.4 TT has a higher cost of operation and maintenance. I mainly want to make sure the 6.4 liter TT isn't known for major problems. My friend has a 2008 F350 with the same 6.4TT engine and he loves it. I figured its always best to pick the collective wisdom of a forum. I value the benefit of your experience. thanks!

Brad pretty well summed it up. I would just have to add that for the sheer power and towing ability of these trucks the mileage is well within reason. The EPA mandates on emissions to burn more fuel so we have cleaner air is; well........ typical of the government. We've pulled the living crap out of our 6.4's and I mean heavy trailers, very little running to town for groceries etc, they make cars for that. Use the Ford 6.4 for it's intended purpose, maintain it like the technologically advanced system it is, read that manual or listen carefully to the maintenance CD. Change your oil religously, keep those fuel filters fresh and refuel at trusted diesel stations, minimize idling as much as possible. Use your winterfront as necessary in heavy, wet snow conditions and keep your eye on your coolant level. And finally, enjoy that critter like no truck you've ever had!!

I hear a lot of bad mouthing of the 6.4 especially from the other brand owners and forums. My real world experience and those of my 4 close friends that have them is not a problem and it tows amazing. Regen sucks!!!!!
I get pretty good milage and on my last trip i got 18.5 empty on hilly 560 mile stretch round trip which is head and shoulders better then my old 6.0 gasser. I do normally get about 16 or so. In town is a different story as it takes some fuel to get 8K lbs+ moving over and over again. I am not a "Ford guy" but I wanted to try one since i have tried the rest and this truck is just better. by the way mine is a 2010 with 9K miles and I have pulled a 12K lb fiver for most of that and commute to work 18 miles each way and run out the regens. I also do 3K-5K oil changes, (3 so far) drain my fuel filter once a month at least or after a long haul, use diesel kleen with each fillup and check my levels at least once a week if not more.

I have a 08 & it has been great truck. As one of the guys said, read the manual and pay strict attention to the the maintenance; do not buy cheap D/F and resist the urge to use bio. Ordered mine in 2/08 and it now has about 17/18K with no major probs. Just make sure you stay on top of the maint(especially oil changes @5K, fuel filters, draining of same).

Well, I think it's actually that the gov't (not sure if it's really the EPA but some gov't agency) just sets the emission standard...so many ppm or such-and-such a maximum particle size. It's up to the manufacturers to figure out how to meet the standard. I doubt that the gov't specified that Ford has to use a filter that requires extra fuel in order to work, that's what Ford, et. al. came up with to comply. And if it's like it was way back in the 70's when they mandated unleaded fuel, etc. the manufacturers fiddle-farted around trying to figure out a way around the rules and then had to implement some half-assed solution until they decided they had to and figured out better ways. It seems to me that these DPF's, etc. are deja-vu all over again...just like the crap they came up with back then. Hopefully they'll eventually come up with something better but we early adopters pay the price.
