IT WORKS!!!
I seafoamed my truck 3 fillups or about 800 mi ago and my first tank I got 10.5mpg, second 11.76 and yesterday I got 12.9mpg. I am not sure if it was the seafoam or not, but I like the results.
I first found the DP through google with problems with my 6.5 (the second day I had it) and learned a great deal about it through you guys. After I sold it I stayed on DP but steered away from the 6.5 section because I did not need the help anymore and did not have much to offer anyone else...
