Hello Folks, My 08 F-350 rolled over to 5000 miles this w/e so I thought I'd share my expirence so far. 08-F-350 XL super cab LB 6 speed manual with HD towing & camper certified 11400 GVWR 18" wheels. I put 1500 miles on it before towing anything then pulled a 2300# race car about a half dozen times. My self & my buds with '99 &'00 7.3s were impressed with the power, and how smooth & quiet my truck is. Started off at 17 mpg, at about 3000 miles (Changed oil at 1500) I was down to 12.3 and I got the injector recall notice. They replaced all 4 on the right bank & changed the oil even though it did not exhibit the over full symptoms. Milage immediately improved to 16.9 according to the OBC and is a little over 17 by the math. Feels great to see the Miles To Empty goto 630 and over on a fillup. That eases the pain of a fillup a little. The truck is still doing great & I love driving it although most of the time I'm driving my 02 Ranger FX4. The truck continues to get good milage. The DPF cleaning cycle will knock off a couple of tenths but it picks it back up within 50 miles. If you guys aren't getting decent miliage with a 6.4 I'd check on the injector issue if I were you. I love this engine mainly because of the iron block & heads. With the 6.0 issues (which are fine after the head bolts are replaced) I can't believe ford is going to alluminum on the scorpions. I hope it works for them. I've enjoyed reading everyones posts here & wanted to share my own.
