    This sounds like a puzzler question. The ramps won't help when you change tires. And without a spare, it will be tough to get the left front to right rear.
    If you have a good hydraulic jack, you can raise half the car at a time. You can manage with two stands and a jack but it's not the safest way to do this.
    Use four stands and don't trust just your jack.
    Now you can get under the car for the diff, tranny and oil change

    yeah, that did sound stupid, eh? i had a few beers in me

    How about 4 2-ton jack stands??

    Then what? Put each corner up in sequence? Realizing my own stupidity, maybe it's best I just pay some garage to do it

    Re: Third Oil Change

    With a $50,000 car it's always best to let a pro do any work that can affect your ride quality or internals. Just my two cents.

    I've never CHANGED oil in my life, I do know how, but for the extra $5-10 I will let someone else - who I can yell at if they screw it up - do it.

    Re: Third Oil Change

    Different strokes for different folks. I look at oil changes and tire rotation as basic maintenance that almost anyone can do with tools they likely already have. It's hard to get any satisfaction from working on your car nowadays because of the sophisticated tools or training you need. I might think twice about slapping a supercharger on my V myself - partcularly due to the warranty issues. But when I do the basic preventative maintenance it gives me a chance to look at other components on the car like brakes & suspension and check for leaks; ie, service you usually don't get unless you have your own personal mechanic. Some of us, like me, have probably done it ourselves most of our lives and the cost of the car doesn't make any difference. My 2 cents worth.

    Installing a supercharger isn't any harder than changing oil, just takes more time.

    Re: Third Oil Change

    I'm with ya, Cal...but I already purchased the ramps and jack/stands and I gotta use them for something.
    I may stick to "simple" oil changes and maybe a CAGS hack, but leave the tires to the Goodyear guy
    Besides, I'll probably detail my undercarriage when I'm under there anyhow

    The ramps work fine for the CAGS mod - this should be first on you list, even before an oil change. Plus, the Caddy dealer/service won't disable CAGS for you, it's definitely DIY

I think I will be lucky to get 10,000 miles out of these F1s.
    I have the wear on the outer edges of my fronts as well (which are now my rears).

    The thread for the 1st analysis is here -

    For the 2nd oil analysis see post #5 in this thread -

    Re: Third Oil Change

    Third oil and (first) differential analysis are in.

    Engine Oil (as stated above changed with filter) -

    still high in SILICON @ 55PPM (but not as high as before) and
    high in COPPER @ 121 PPM

    "ANALYSIS INDICATES TYPICAL CONDITIONS FOR BREAK-IN. The noted values are for monitoring purposes only. RESAMPLE at the next scheduled interval."

    Rear Differenential (fluid UN-changed) -

    high in COPPER @ 225 PPM
    high in IRON @ 762 PPM

    "ANALYSIS INDICATES CONDITIONS REQUIRING CLOSE MONITORING. POSSIBLE SOURCES include: Gear or bearing wear. PERFORM the appropriate diagnostic tests. RESAMPLE at the next scheduled interval."

    I'm not sure what to make of this but I'm open to hearing others thoughts.

    I can understand the heavy metal contamination from bearings and gears. What I don't understand is the silicon contamination in the engine oil. The Corvette forums say that silicon contamination in the LS6 is common due to leaching from gaskets or sand casted parts. Seems to me that GM should figure out a way to eliminate the silicon or silica by using different gasket material and/or better flushing techniques of the engine components before and during engine assembly. We as owners, obviously are expected to change the air filters to prevent silica dust entry into the engine via the air intake.

    I changed my oil at 700 miles and 2700 miles - almost identical to your intervals. Due to what I've seen here I'm going to change it again a few more times at 2000 mile increments. Thanks for your input.

    Re: Third Oil Change

    Silicon in engine oil can also caused by dirt (sand - "silica") ingestion through a leaking air intake clamp or intake manifold gasket. Are you using a cold air intake with a K&N style oiled filter?

    Negative on aftermarket intake/filter - all stock here (for now). I dont like either of the 2 currently available options enough to spend $ on them.
