My 07.5 has about 75K miles and so far has been great. I was wondering about others that have 100K or over how there's are holding up?
Thanks

 

my moms 07 is running better then ever once it 100k be for then you had to take it to the dealer at least 2 times a month. but now it has 114k on it and runs supper good .but still only get 14 or 15 mpg on the way back from california i was getting 7.5 mpg with a 3500 dually on the flatbed NOT COOL. but the truck ran good. and it still has the stock clutch in it

 

Wow never knew that these trucks got such poor fuel milage. I think Ill keep the old 12 valve...

 

Must be an isolated incident. If mine got that Id toss it too. I see 16.5 to 17 on average around town and 19.5 to 20 on the highway/interstate.

 

I would say isolated also. My 07.5 6.7 gets 16.5 AV and 19+ highway bone stock.

 

Mine gets around 19 bone stock with 33k.

These trucks aren't broken in until 100k

 

My 2009 has only 14,500 miles and running 65 MPH interstate yields 20 MPG. Pulling my 15K # fifth wheel at 65 I get 11-12 MPG. (Totally stock) Love my truck.
