So my buddy is looking at picking up an 09 F-250 6.4L diesel 4x4 with 73K miles. He's a gear head as well and is more familiar with these trucks than I, but I was hoping to get any feedback y'all had on them.

The big question is real world fuel economy. If he gets the truck, he will be putting a lot of unloaded highway miles on it. Anyone have any real world experience with teh MPGs on this beast?

Also welcome any other feedback on this truck. He's replacing an 06 Silverado 1500 that is giving him some trouble of late.

Thanks ATG!

The best source for real world numbers, here is your friend's purchase:

Not too good for a diesel.
It is a small sample at only 6 trucks, but the 08 has the same engine and the same numbers, and 41 trucks and 360 K miles recorded.
He may not like them, but the Dodge Diesel of the same years has a solid 15% advantage.

Not so many duramax records, but this is enough to look at:

Everybody I know looking for a diesel only gets it for towing and have known more than one who has traded diesels back to gas if they don't tow.

Because the maintenance is brutal on these trucks, turn a screw and its a thousand bucks. Yes you get good mileage however if you blow a G on getting an injector replaced it take a long time to make that back up

Fords get the worst mileage out of the 3 big diesels.. IMO they are generally the most un-reliable and the lowest on power. I personally go with the Dodge's as the Cummins is the best diesel motor in those trucks, but the Chevy has the Alison transmission which is hands down the best.

The 2008-2010 cummins had some issues with the EGR putting to much soot into the turbo. They work great if you remove the emissions, but then you wont pass the inspections, and your vehicle will be illegal to use on public roads. It is also a 15k fine for removing it(in my state at least). But they run very nicely once you remove the EGR and put a good 4 or 5 inch turbo-back-exhaust.

That is a flat out work truck. Period. Every time that truck is started it should be pulling a load and making you or saving you money or it's a giant waste.

The new F150's with the right equipment packages should handle most anything you'd ever tow. If you need more than a F150 it's likely your friend would already own one.

I know LOTS of people in the business of moving large amount of equipment very far distances in short amounts of time for a living and people who pull huge travel trailers. They all pretty much disagree with you. They all have Fords. My dad's friend had a Dodge and pulled a travel trailer with it until he was convinced to go Ford. He bought one and on his first trip he found out why.

My dad's 2011 F-250 gets better mileage than my 2009 F-150 even when you take into account the difference in fuel prices. Not by much but it does. When pulling a load it gets significantly better fuel mileage. It is also a lot faster with a shit ton more power. I just didn't want something that big.

I work construction, and have been around it my entire life. I've been around diesel trucks my entire life. Starting back with early 90's and clear up to 2010+ and I'd take the Dodge over all of the others. With Chevy the second and Ford the last. I will most certainly note that the old 4 speed automatic transmissions that Dodge had could not properly hold the power of the Cummins so there was alot of issues there.

You might notice that both the 08 & 09 Fords had that same 6.4 engine... Now notice it was only a 2 year engine and there is a reason... They (Ford) worked and worked on the 6.0 liter to get it right but still had issues... I talk with to many Ford owners that all tell me the same thing its either go with an older 7.3 truck or get the newer 6.7 engine for both fuel economy and reliability... But what should I know I own a Duramax that gets 20MPG...:cool: (hint...)

I averaged 21.56 for the last year as a truck, and 14 with the 10,000 pound 12' 6" high 5th wheel. High number was 26.3 over a 600 mile trip.

i have put about 100k on ford trucks with 6.0 and 6.4 engines in the last 4years. I would never own one, I would never advise anyone to own one. Our department has around 20 of them. We have spare trucks just because we always have 2 or 3 of them in the shop. the emissions systems stuck, the transmissions suck, the turbo's last about 50k, the fuel system is an absolute joke. the truck assigned to me has spent about equal time in the shop and on the road. from 60 to 140k it has had: 2 turbos, 2 high pressure oil pumps, 2 or 3 sets of injectors, fuel pump, water pump, complete emissions system, 2 egr valves, a few glow plugs and a few other things.
They have no power when they are running correctly. I am convinced ford sells them cheap for fleet service because they know they will make up for it on parts.

I have never gone more than 5k on an oil change and check the fluids regularly, and bring it in as soon as i can when it is not working correctly. both fuel and air filters every quarter.

I would buy a duramax or a dodge. i would push the ford off a freekin cliff if i could.

jury is still out on the 6 2011 and 2012s we have, but they seem to be a heck of a lot better. they also have more power and drive like modern trucks, not like something from 40 years ago.

and i am usually around 12 to 13 mpg. I do have a tool rack on the truck and 100 gallon aux tank though.

I have experience with the 4x4 2500 Extended Cab Chevy, LLY Duramax Engine, and Allison 6 speed automatic transmission. The truck can get up to 17MPG highway and never goes below 15 in mixed city/highway driving. On the freeway it can get more then 17 but I have minimal experience with it on the freeway.

That is not a good powertrain, not like the 7.3 PSD is.
I'd go with a Cummins too myself, but I have always loved Dodge trucks.

I'm a ford guy to the bone but the 6.0 and 6.4 motors are absolute crap.

I've got a 2012 F-150 Super Crew... with the 5.0 V8 and I get 22 HWY depending on the head wind and how much of a hurry I'm in. My config with my taller gearing tows 8000 pounds which is more than enough for me... lower gearing on the 5.0 can get you to 9000, and the ecoboost V6 can get you to 10,300..... But if you need to tow that much weight, you probably should go F250, or one of the GM/RAM 2500 series.

I've been real impressed with my Ford so far... and I traded a Dodge - which had been a great investment for the 13 years I owned it.

Does he need the extra towing capacity or something?

My dad had a 2001 with the 7.3, a 2006 with the 6.4, and now he has a 2011 with the 6.7. The new truck is by far the best of the bunch in all departments. Even without a tuner he says his gas mileage and power, even when towing a heavy trailer, is much better than the previous two trucks.

The 6.4L is the reason Ford stopped using Navistar diesels in their trucks. The 6.7L is a clean sheet in-house design.
