I purchased my 2008 ford Super duty in 2007, One of the first. I now have 218,000 on the 5.4 gas engine. Only 1 set of brakes. New alternator at 100,000 mls. I am a stone mason and work my truck hard. Around 120,000 mls the truck made a engine noise when I started it, almost 100,000 mls later I have the same noise. No change, I always change my oil, I love my truck, Would never buy anything but a ford truck period!

I bought this vehicle used in 2009 with 32,000 miles in the XLT trim. The vehicle had a bad front end and lousey fuel mileage. I knew this when I purchased the vehicle. I have invested in a chip to improve fuel mileage along with a banks air filter and magpro exhaust system which improved fuel mileage from 12 to 18/20 mph. Different tires also helped improve fuel mileage. I installed heavy duty air shocks and replaced the front springs with heaover springs and stabilizer bar to the front end. I also installed side step bars, tool box, backup camera, fog lights and trailer brake and other items. This was cheaper than buying a more expensive vehicle from the dealer
I put a Bank's toaner on it to improve fuel mileage and the dealership blames everything that goes wrong on the tuner. I had to take it off. With the tuner I got 21+ mpg hwy, 18mpg in town. Without tuner 12.5 Hwy., 8.5 around town. I do not understand why ford won't offer something that can improve the mpg.
Really folks this is a great truck and even better if you do some very minor tweaks. There is lag when you want to pass someone. Ford put that "feature" there to preserve the life of the transmission. The gas mileage stinks becase the EPA said we needed cleaner burning engines.. oh the irony. You can feel bumps more compared to chevy. Chevy uses IFS on the front end and when that chevy IFS breaks, then you see the reason ford stuck by solid front and rear axles. With one modification you can increase your HP and Torque by 50%, have 100% throttle control when passing, and improve your MPG by 30%. You can do this by buying a tuner for about $1500.00. Check out a diesel forum and you'll see.
After 3 recalls a driver door handle that fell off, water seperator going bad, and a rattle in my driver door I still love this truck. The king ranch pkg is excellent and the truck still looks like new after 60,000 miles. Engine has been bullet proof with excellent power. Gas milage for a big truck is good at 18 with no AC or 15.5 with the AC on.PS the rattle in the door was fixed by a simple piece of electrical tape applied to the door latch post where the door meets the frame. This is a nice addition to my $50,000 plus truck LOL!
