Ford 6.0L Power Stroke Diesel :: 2005 - Poor Fuel Mileage?

I just bought my first diesel truck back in November. It's a 2005 F-250 with the 6.0L and the 5 spd torq-shift automatic tranny. Last weekend I drove the truck to South Carolina, about a 600 mile round trip from where I live. On the trip the truck only got 13 mpg! I wasn't towing a trailer and the truck was empty except for me and my suitcase. It's not loaded up with mods or anything, it's completely stock power wise.

I'm extremely disappointing, especially since a friend of mine has a 2006 F-250 identical to mine and he gets up to 21 mpg on his. What can be done to improve my mileage? I'm not a lead-footed driver, and the trip was done with almost all interstate and highway driving, very little driving on back roads or stop and go. If this is the best the truck will get, I'm going to sell it and buy a F-150!

Ford 6.7L Power Stroke Diesel :: Instant Mileage Display Froze Up

Own a 2011 6.7 diesel, 59K mileage, short bed 4 WD. Was driving at 70 mph and noticed my instant mileage display read 0. Usually I see a instant mileage reading of at least 16. No regen was in progress. Steady gas throttle. Display could be changed to other screens. After a few minutes it came back. But it jumped to 16 and did not ramp up.

Ford 6.7L Power Stroke Diesel :: Changing The Oil Filter?

OK what is the trick to changing the oil filter on the 6.7 without making a mess. My last truck, which was another brand, if I would let the truck sit for a couple of hours, I could get the filter loose, put a zip lock bag around the filter, & remove the filter without any drips. With the 6.7, even if I let the truck sit overnite, it seems like the oil doesn't drain from above the filter, & as soon as it comes loose my hand gets a bath. Any tricks to changing the oil filter.

Ford 6.0L Power Stroke Diesel :: Changing Right Exhaust Manifold?

How difficult is it to change the passenger exhaust manifold? I have just finished replacing the left exhaust manifold. The biggest issue was rusted fasteners and inexperience. Have torches. Any you tube videos show the left manifold being changed but not the right. I do not have a hoist and work in my driveway. Is the right side more difficult and should I leave it to someone with a hoist?

Ford 6.7L Power Stroke Diesel :: 2013 - Changing Fuel Filter?

I was going to change the fuel filter on my truck yesterday, but couldn't figure out how the guard comes off. It has a bolt but it also has a rivet in it and looks like its all one piece so Id have to drill the rivet to remove. I tried to just spin the housing off.

Ford 6.7L Power Stroke Diesel :: 2014 - Changing Fuel Filter?

Noticed change in power after changing the fuel filters on 6.7 .... Seems like it has a fuel restriction at times maybe even air somewhere in the line. Thought I felt the truck hesitate after hitting the gas and Cavitating when I hit the gas petal. Both new filters are motorcraft parts. I did follow the procedure after installing filters by turning the key on 6 times waiting 30 seconds in between. Could it be a problem with the fuel pump. I should say I didn't have this until I changed the primary filter.

Have to do a brake job on the truck? I took mine truck in for a CEL (New EGT 12) and during the Multipoint inspection they saw the brakes were pretty worn (and wanted an upsell im sure). I only have 49k miles and the fronts only have 20% and rears 30% of the pads left. So I get to spend a few hours this weekend doing the deed. Anything special to look out for?

Ford 6.7L Power Stroke Diesel :: Aluminum Particles In DFCM While Changing Fuel Filter?

I changed the fuel filters today and saw a couple of small pieces of what looked like aluminum or aluminum foil in the bottom. Nothing in the filter itself it still looked good. I will try to post pictures later but I'm not sure it will show up. I don't recall seeing anything the first filter change and this is the second. Is this normal?
