[THE LEGEND]

I have a 06 Duramax. I put 40,000 miles on it the first 18 months. I've put 2,000 on it in the last 6 months. I change the fuel filter every other oil change. I used that stuff in the gray bottle you get at the truck stops sometimes but not on a regular basis. I hav'nt had any problems. I've heard some that had filter problems though.
