There has to be a better oil drain plug gasket

    On my 96SL2, I replace the drain gasket about every other oil change.
    It gets rather shredded by the second oil change. I am not over
    tightening the plug. Is there a better gasket somewhere that I can

    Saturn usually replaces the drain plug when they change the oil, so they
    should have lots of stock, so get one the next time you change your oil.

    Check for rough edges on the plug or mating surface of the pan.

    The last time I was at Saturn and mentioned that same problem, the parts guy
    handed my about 15 of them, free of charge. Ask!

    I would suspect you have a rough spot on the pan. My gasket lasts about 4
    changes before I must change it out.

    Or he may be overtightening the plug.

    I've replaced the gasket only one, maybe two, times in 226,000 miles on my
    2000 SL2. Are we talking about the same gasket for the oil drain plug?????

    The gasket is actually a plastic washer around the oil plug/bolt.

    Mine is a gray rubber part.

    I had (hopefully past tense) the same problem with my 2000 SL2. It
    now has 200,000 kms on it, so I've changed the oil a few times.

    I found to my surprize (even though it was tearing after a single use)
    I could get away with not changing it until it was at the point of
    ripping in half and it still never leaked.

    A few oil changes ago I stopped by Canadian tire and bought some of
    the generic nylon oil plug gaskets (1/2" I think - the OD is just
    about right too). I installed two as they were a little thin. Over
    the past 3 changes they have "moulded" to the perfect shape and
    tightened up on the oil plug threads. They are working perfectly so

    BTW, my wife's 2000 SW2 with 70,000 kms on it doesn't have the problem
    at all. It's still on the original plug and gasket - never torn,
    never leaked.

    I examined both oil pans carefully and concluded it must be related to
    the fact that the SL2's oil pan stamping has a slight rise (not a bur)
    close to the hole (where the "nut" is attached to the pan). My theory
    is this causes the (very soft/weak) gasket to get over stressed before
    the metal OD ring on the plug hits the pan. Even torqueing the SL2's
    oil plug well below the spec the, gasket would tear every time.
