Are the 2010 6.4 dependable?
Did Ford fix all the problems?
What is the milage for a F350?

6.4's are very dependable as long as you don't mind popping the hood regularly. Many recommend following the "Sever Duty" Maintenance Schedule.

SRW? DRW? Gears? LB? SB? CC? Expect 10-14 mpg depending on trucks specs and options.

 

Agreed, the 2010 would be considered the most dependable of the 08 production run's. Good maintenance is key. Mileage is ruff due to all the emission requirements

 

You will want to check all fluids and see what there is for service records. You wil want to have the coolant tested for nitrates.

Be sure to look at the radiator seams down by the tow hooks especially. Radiators are the weak point, bad design.

Look at the tail pipes, should be clean to grayish...if black then why?

Get an extended warranty since this is a new to you truck.

If you work it hard it will run good.

 

All of the above including regularly checking the water separator and using stations that get allot of service. These newer trucks don't play so well with water in the fuel, regardless of whether it's an 08, 10 or even 11.

 

My tailpipes are turning black. Should I take it in???

 

If you want to throw them for a loop I suppose you could..but what would be the point since you are deleted?

 

What physical parts did Ford improve that were on the 2010 and not on the 2008 0r 09 MY? Ford made changes in mechanical parts to the 6.0 starting in 2004 (and there were many) that were not interchangeable with later 6.0 engines, but I know of no part modifications between a 2008 and 2010 engine other then computer re-flashes.

 

Oh yeah they did. The air damper on the bottom front of the 09/10 is a couple inches longer than the 08.

 

Unless it was a 2008 Job3.

 

I'm not sure I would link "popping the hood regulary" with very dependable.

 

it does, on the 6.4 maintance is a must, cannot neglect it.

 

Now I understand the meaning of "popping the hood"

To the OP: Just so you know my cousin (Ford diesel tech) replaces more 6.4 long blocks than 6.0 & 7.3 engines combined.

My advice is to purchase an extended warrenty and "DO NOT" modify this engine in any way that would void that warranty.

 

There has been alot of improvements since the early 08's from radiators and components, front engine covers, head gaskets to inter coolers,programing and the list goes on. The 09's received allot of the changes but us early 08 guys were in a since the Ginni pigs just look at all the tsb's....lol, alot might not be changes directly but mabey better suppliers with some part improvements

That would be good advice for any late model car or truck. Strange we haven't heard much about new long blocks or engines on here. In the past three years I only recall one or two. Maybe he's working on a lot of fleet trucks that are not being maintained. I'm sure some companys "buy em and run em" which would be a bad policy with the 6.4L. As to modifying them, there is a pretty strong and growing body of evidence that modding (deleting the dpf) the 6.4L is the way to ensure a long and trouble free life. Getting rid of the oil dilution can only be good for the engine. But, you can't very well do both, delete and buy an extended warranty. Everybody will have to choose or sell. I'ts a tough call for sure.
