    Default Where is the drain plug on dry sump system?

    I don't own a C-6, or a Z06, but I wanted to know how you would go about changing the oil. I wanted to know where the drain plug is on the dry sump oil system. Does it have a drain plug? I saw a show featuring the building of Vettes on cable recently, featuring the Z06. The Z06 uses a dry sump oil system and therefore there is no oil pan on the engine, a separate reserve container. Wondering how that is drained for an oil change.

    Nope, but someday.


    HI there,
    There is an oil pan or SUMP as most call it, per se, but there are 2 drain plugs.
    One is for the sump and one is for the holding tank and lines going to it.
    Allthebest, c4c5

    The "pan" plug isn't exactly dry but it holds less than a quart. The other plug holds the rest of the oil. (7 more quarts for 2006-2008, and 9.5 add'l quarts for 2009MY cars.)
    Changing the oil is just like any other GM product, just pull 2 plugs instead of one!
