    CTS-V (LS6) Early Oil Analysis

    As you may (or may not) recall I did my first (motor) oil and filter change at approx 620 miles on my new V (after following the recommended break in proceedure to the "T"). I also sent out a sample of the oil for analysis. The results are in - and they are mixed (I hate to be a complainer - my friends will tell you that I never complain, and it seems like all I ever do to ya'll on the board is post issues I'm having with the beast ).....

    Quote from the report:

    ANALYSIS INDICATES CONDITIONS HIGHER THAN TYPICAL FOR BREAK-IN! Silicon attributed to assembly/break-in. CHANGE the OIL and FILTER(s) if not already performed. An ADDITIONAL SAMPLE is REQUIRED to determine a specific rate/trend. RESAMPLE at the next scheduled interval.

    The 2 values there ranked "HIGH" are -
    Silicon (173 PPM/by wt) &
    Copper (311 PPM/by wt)

    All other results are normal/ok.

    Now with ~1600 on the clock I think I'm going to have to change (and resample the oil) at ~2k. Begining to think it was a REALLY SMART idea to change the oil early on.

    Thoughts?

    Not blindly sticking up for this car but does this analysis specific for an 8 cyl LS sbc? All engines break in differently and obviously an 8 cyl will have higher contents of metal in the oil than a 6 cyl just because it has more moving parts in it. Just a thought.

    Simply put no. This "abnormal" result was based on what normal levels should be in engine oil (not car/engine specific).

    Here is the full list of what got tested:

    and

    http://www.analystsinc.com/physical_properties.html

    all other readings were in normal ranges. I will probably drop oil and do another test in the next week or 2.

    Re: CTS-V (LS6) Early Oil Analysis

    Is there somewhere that we could get a comparison to the contamination levels in a new Z06? Like GNScott said, all engines break in differently. I wonder what the average expected contamination for an LS6 is? I hope that this doesn't signify problems with your engine. The LS6 is a tried and true engine, there shouldn't be any problems with it. But sometimes these things happen...

    Anyone own a Z06 that has done a similar study?

    I'm actually going to go hunting on the Z06 boards and see if I can find something of a comparable nature. I'll post links to what I discover. I was hoping some of them (the Z06 owners) might be browsing here and can give further input.

    How mush did this test cost you?

    Roughly $20, tests usually run ~$20 plus they charge you to ship the test kit to you <$5 (get a few - save on shipping) - sample shipping back to the lab is usually included (there are a number of places that do analysis - I can't speak for most of them).

    Order your test kits here:

    I can also post the whole report (in jpg) if anyone is really interested (just speak up).

    Re: CTS-V (LS6) Early Oil Analysis

    So far I haven't found an report on oil this early in life, but it seems that first 10k or so the Silicon and Copper both stay high in the LS6 (and also the relatively similar LS1). Copper stays elevated for (up to) ~30k miles (yipes!). For those who wish to do more reading -

    You'll also find the folks over there strongly hinting that LS1s and their derivatives don't like 5W-30 oil, they much prefer a 10W-40 or 15W-40.

    I think they standardized on the 5w for cold climates and cold starting. I will go to 10W for the summer. 5w is water when its hot.
