    Default 09 Yukon- synth or conventional from factory?

    Hi all, I have a question about my new 09 Yukon (love it).

    I have to top off the motor oil and I'm not yet to my first oil change. I was wondering if the Yukons roll out of the factory with conventional or synthetic oil? I am assuming I have to use the same kind and I can't mix, right?

    Let em know, thanks!

    not much help on answering your question, but why do you need to top off the oil on a brand new yukon before your first oil change. I would think conventional but don't take my word for it.

    A buddy of mine bought an '09 Sierra a few months back and all the fluids were synthetic...but the big issue would be why are you having to top off the oil in a new truck?
