MPG

What kind of mileage are you all getting with your 6.4?

[wired1]

BAD!

Ditto.

However, if your looking for some serious mileage, take a look at Natruell's CNG Conversion Kit. Testing has shown 40mpg on a PowerStroke.

with out deletes I got 14 highway. With deletes I moved up to around 17 average on the highway with speeds 65-80 mph.

Im getting around 13 the last few tanks. Not to sure if it is the winter fuel but it has gotten worse since winter

[blackcloud2k]

Yes winter fuel doesnt help. I dont really even bother checking my mileage in the winter. I know its going to suck with winter fuel and idleing alot.

15 mpg with dpf delete

Since exhaust, intake, and dpf/cat delete my cheetometer says I get about 20-24 highway and 14-18 city... People will say the MPG gauge inside the truck is not accurate, regardless if it's accurate or not it makes me feel better seeing 20+ mpg

Thanks for all the replies. I'm thinking about selling the 7.3 and getting a newer one. Now I'm not to sure.

I went from about 16-17mpg with my chipped 7.3 to about 12mpg with my tuned 6.4 ... not very thrilled about that but the 6.4 is a heck of a lot better ride and tons more fun to drive.

(that's all city driving with a 3.73 rear end)
