2008 Ford F-250 Super Duty XL 4dr Crew Cab SB (5.4L 8cyl 6M)
I bought a 2008 F350 4x4 King Ranch LWB 5.4L. This is my second diesel and definitely my last Ford diesel. Last one was a 2004 F350 that did about 18.4 mpg and then I get this low sulfur petro burning sponge at best demonstrated 11.8 mpg. Yeah I would probably get 13mpg @ 65 mph but I am in TX and the speed limit is 70-80 on the interstate. I have taken it to the dealer and all they can say is be patient it will get better. Wrong answer. For a 50K truck I better get results. The dealer has given me cash, free tank of gas, free oil change, and other things but Ford engineers screwed up big time on the MPG in 2008. I should have went back to Chevy with a dura
MPG. That emissions cleaning system that blows white smoke when it cleans the intake out. It looks like you blew an engine going into turn one.
