Tricks to improve mileage on 6.4 Twin turbo???

billybigrig · #1 (**permalink**) 11-13-2007, 01:09 PM

I bought a 2008 6.4L F-350 crew cab 4x4 in april of 2007. I have owned 3 of the same trucks in earlier year and had way better fule mileage(6.0L). I was wondering if there are some things a guy can do to increase the MPG without voiding the warranty(eg. chips and exhaust). Are there any ways that I can get my F-350 srw to get better the 13-14 MPG?????

not sure their is anything you can do without voiding the warranty... just wait it out and break it in... i heard you will gain a few extra MPG after it reaches 10k+ miles on it

I have already got 20,000 miles plus on this truck and it has virtually stayed the same. It also dosn't seem to matter if I drive at 60 mph or at 75mph...... the milage is roughly the same???

i'm around 13-14MPG and not really improving. hopefully someone can tell me a quick fix or else I may have to look at other options which I am not too sure what they are but will hopefully find out soon!

13-14mpg for an 08 is very good....

An air intake and exhaust with the "vents" are about all you can do with out crossing the line on the warranty, with a programmer you are tap dancing on a land mine and if you get rid of that DPF, which is the problem, you void the warranty...

Well I know that my 06 f-350 did a lot better fro fuel milage. What is the DPF? Is that what they refer to as the "taddler" . How does it work?

What about the exaust vents........ what are they ........ are they kind of like the stock exhaust tips?

And what would be the best air intake to get?
