    Hi, I have a 2008 LT3 Z71. The dealer is still getting me a owners book because the lease return that I bought did not have one. I am going to change the oil and I do not know what type or weight to use. Does it have to be syn. oil or just normal oil? what weight? this truck does have active fuel management with a 5.3L. I have a 2006 300c that has a displacement engine and I have to use 5w20 in it. Anything else that you can tell me would be helpful. I am waiting on the owners book because they are on back order....right! I really doubt I will ever see it!

    Thanks for the quick reply. So this vehicle does not have to have synthetic oil?

    www.Goodwrench.com/chevy-owners You can download your manual from here. It's always good to have it in .pdf format. :glasses:

    Thank you so much mmorgan1865! I am going to do that right now! Like I said I am not holding my breath on the dealer getting me one.
    Thanks again,
