I recently purchased a used 2006 F350 Dually, Lariat, FX4, 6.0 diesel with 4.10 gear ratio. The truck has 150,000 miles on it. I know the bad reputation of this motor and only bought it for the following reasons: Its in like new condition, purchase price was half of book value, and I purchased an extended warranty.
The mpg gauge says it gets 11.2 mpg. Seems pretty poor to me. I have hauled a few different large goose neck trailers with it and it seems kinda gutless. My 1999 f250 with 7.3 diesel with a chip will run circles around it and out pull it.
The 2006 does not blow any black or white smoke that I have seen. When its loaded it takes almost all of the pedal to do 70 mph. There is little pedal left at 70 and essentially no pickup after that. I have changed all oil filter using a ford filter etc. I have also changed both fuel filters using ford filters. The air filter as been cleaned as well
When I first got the truck I tracked down the previous owner and he told me the only problem he ever had was the injectors (with in few first few thousand miles). I had not pulled anything with it at that point.
I talked to my wife's grandfather who had one of these trucks. He said he thought he had to have his reprogrammed a few times at the ford dealer. He also told me he pulled his 32 ft fifth wheel as fast as 97mph with his 6.0...........
Does any body have any thoughts as to whats up with my 6.0? The truck runs great but just don't seem to have the power. The turbo psi gauge gets up to about 30 max when I'm towing.
Thanks for any thoughts
