Hey, I'm new to Diesel Place and to Duramax. I just bought a 2001 long bed extended cab Chevy 2500HD Duramax in Denver last week for $13K. It has 122 K miles on her, a programable chip (set on the middle setting I am told) and runs like a scalded ape. Whats amazing is I got 22 mpg coming home to New Mexico and that was climbing two mountain passes. I drove her easy, not over 65mph, and blows good black smoke when I step her down. Question- do any of you Duramax owners put a fuel additive to try and save the injectors or the pump. Sure appreciate any feed-back. Thanks, ho9styl

YES, you better add some additives.....................

Which fuel additive do you reccomend. I have used Diesel Power (winter and summer brands) for at least the last 10 years of driving Diesel P/U's, but am not sure it is the best for the Duramax. thanks.

Take a gander through the fluids discussion threads here...:

Most run Stanadyne or Power Services and get great results. I personally run stanadyne.
