I have been trying to find my (actually any) diesel supplement that was SUPPOSED to come with my owner's manual. I didn't get one. My manual refers to the diesel supplement for ALL things related to the Duramax engine.

I was looking for capacities and even reccommendations for oil, fuel, etc. Did anyone else get one with their truck? I went to the dealer, they were totally dumbfounded about it. I showed them in the manual where it refers to it.

They are supposed to be 'checking' on it, but you know how that goes...

What am I missing? Also, are there repair manuals either here on this site, or available through the dealer, even aftermarket for this truck?

Also I am worried that I am asking questions that have been covered. I have tried the faqs and the search function, but I am not getting the info I am seeking. Am I doing something wrong? I know I have asked a lot of questions, but I am just really wanting to know.

Thanks for all your answers and patience!
