F250 6.4 review?

[BIGTERRY75]

yep...the 6.9 was a good long lasting engine, just didn't have the power the turbo 7.3 did. I think the 6.4 is the last of the International influenced ones, and Ford wanted to go larger CID, but International said not with us.

BTW if one were to delete, tune and drag race any thing, be prepared to break stuff...if ya want a race truck build one, if you want a daily driver...then just drive it.

If you delete them, tune them, and just drive them. The delete will pay for itself in fuel economy alone

Mine is deleted. The fuel savings is minimal, almost non existent. Last I checked, about 1 mpg overall.

The delete is solely to protect the engine and keep the soot from going back into the engine/turbo.

I never understood the need to get good fuel mileage in a 3/4 or 1 ton truck meant for pulling, hauling and riding like a tank. City boys need to go back to half tons if they are concerned about mileage.

6.4 no problem

My 6.4 was great , was left stock and never had a problem with it .
I saw what tuners did to the 6.0 , turned them into time bombs !!
IMO the 6.4 and 6.0 where not design to " unleash the power "
Stock the 6.4 produces plenty of power and torque ! There are millions of 6.4 still in yo man duty

That does not make any sense with your fuel economy. Something may be wrong in your tune?

I am running the H&S Minimaxx tuner with EGR delete as well as the DPF delete. Always use the ford filters for fuel and oil and run Rotella T6 oil and change every 5-6k miles and use CAT coolant. Drain youre water separator every couple weeks. Keep up youre mantinence and these trucks run for a very long time. If you baby a 6.4 you will have problems. These trucks like to work. Keep an eye on your temps while towing and avoiding over boosting the truck to often and you will be very satisfied. I get 17-19mpg .

No reason not to get the best mileage possible. I don't know anyone that goes looking for the vehicle that gets the worst mileage.

According to that logic, the 7.3 would still be in all their trucks...

Emissions is why they had to stop using that truck. If the 6.4 engine was so great they'd still be using it.

X2 7.3 couldn't pass emissions

Unlikely.
The 6.0 disaster is what got the wheels rolling for Ford to build their own diesel.
But yes, the 6.4 is not by any stretch a great engine.

Stay clear or throw about 10k in the motor and trans

Read this. We used to see these trucks in the shop weekly if not daily.
