I just bought my truck on Tuesday, it currently has 29,506. It's a 2008 F-250 XLT 4X4. This is my first diesel and I'm really enjoying it. I read a lot about it before I bought one. I like this site too, I have learned quite a bit.

 

I would change the two fuel filters, the transmission fluid, & the oil & oil filter

 

It's not even due for a trans fluid changing yet is it? Fuel filters certainly wouldn't hurt and oil and oil filter is always a good idea.

 

The FORD MANUAL say transmission fluid change at every 30,000 miles

 

Cool, I appreciate it guys. That stuff was already on my mind. What are some other things to look at or change out? After I do a good overlook of it, that's when I'll start modding it. I was looking into DPF delete, EGR delete, intake, exhaust, and a tuner. What do you guys think?

 

My 08 Super Duty XLT was purchased in 2011 with 30,000 on her. I now have 60,000 miles. I had a lot of DPF errors, even to the point (4) where the truck just shut down and I had to tow it to Ford, who said there was nothing wrong with it and if it shuts down it will restart in an hour of two. No radiator issues in the time I have had it.

Now that DPF is deleted I have not had any issues with her.

 

My 2008 6.4 has 55,379 miles & no problems

 

Just turned 80 thousand on my 08 6.4

 

My 2008 6.4, has 57, 225 miles & still no problems
