    Not a good sign.......cut the filter apart and see whats in there. You can also send a sample of the oil in to get analyzed....I am not sure who does this though

    How did you find the shavings? Does the drain plug have a magnet, or did you see them in the old oil?

    See if a magnet grabs them- iron vs aluminum
    Not that it is good either way.
    Like poncho says-cut that filter open-now
    new filter-do it anyway-
    if it is chewing something up-you'll have metal after just a few hundred miles(or less much less)

    Based on the fact I've never seen metal in the oil of my 203,000 mile 5.7L Vortec I think something Is up. I've only seen metal in the oil of one engine I have worked on and it had thrown the push rod through the side of the engine. The only time metal in the oil may be normal is the first 3,000 miles of operation because the motor is being warn in.

    I found them in the bottom of my oil drain pan and on the magnetic drain plug. I do have an extended warranty and im good for the next 4 years. But they will not drop an engine unless theres full mechanical failure. But im assuming by every ones post that this deff not good. Engine sounds perfect and puts down the power with no problem and holds 40 psi at idle. Im using 10w30 f/s super tech oil. I've read great reviews on that oil but only on the internet. Am I being mistaken? Also really no need to open oil filter because its all over the drain pan that I dump my oil into.

    All over-
    You mean LOTS of metal flakes?? Not just a few?? NOT GOOD!
    Are they magnetic-stick to the magnetic-meaning iron
    Lots of metal flakes means-don't stray too far from home
    No long trips-keep your tow insurance-AAA or whatever in force.
    I would still pull the filter-cut it open- if it is filled with flakes--don't drive far from home.
    I had a motorcycle-lots of metal in oil-
    but it still ran-it was the cam and rocker arm follower-eating one another-
    but it still ran-sounded a bit "metallic" -but it ran.
    Stay close to home-that sucks
    Super tech-isn't that a discount oil-cheap oil-??

    Metal flakes that can be seen with the naked eye should be trapped in the oil filter. With an engine with that many miles, you should be getting very little metal wear anymore.

    I was not aware that GM put magnetic oil drain plugs in their engines.

    Does not sound good. I think if I were you I'd make sure all of my maintenance records were up to date. Does your owners manual specify 10W-30 for the temperatures usually seen in the area that you live in? I think I'd continue to drive it as usual, hoping that it will fail before the warranty ends, or better yet keeps running well..... far beyond the warranty expiration. Good luck!

    (you didn't cross thread the drain plug did you??)
