unless you are a idiot you wouldn't wait to 10k to change your oil. no matter what it says or people tell you, you be the judge. depending on color and consistency you can judge if its time to change due to thermal break down.
change it every 2k to 3k. you can go more but like previous people said i wouldn't push it unless you want to buy a new engine.

^^^ There are thousands of oil test that prove that the oil is in go shape and the addive package in the oil is there doing its job for longer then 10000 miles. Idiot or A someone saving money and still maintaining proper lubercation and maintence to there engine, YOU BE THE JUDGE.

You might want to tell that to my 190k mile strong-running car, it apparently didn't get the memo.
2k-3k is like brushing your teeth 11 times a day, really not neccessary at all. Especially if you're using a good synthetic.
Read this forum, it has oil analysis test results from a variety of cars with a variety of oils at a variety of change intervals. Some of you may be surprised at how good used oil can look at extended change intervals.

I wanna see the guy running 30k oil changes go up to 100k, then we can see screw drivers stand upright in his heads when he pulls em off!! All kidding aside, an oil analysis is the best way to tell oil condition, as for me, I'll stay over **** about my oil changes(3-5k miles)

Lol. Only in America is it accepted practice for people to spend extra money on synthetic oil and still change it every 3,000 miles.
x2 to both of you. Anyone that's done any research at all would know that changing synthetic oil every 3,000 miles is a waste of money...nothing more. You're essentially wasting perfectly good oil.

People i know where going nuts when i told them that i change my oil sometime after 5k miles of use.

That probably has more to do with the level of oil getting low than it does the oil requiring a change. It doesn't take much of an oil level drop in some cars to notice that type of sound.

Oil "breaking down" is more of a by-product of contamination and not actual wear to the oil. Without contamination synthetic oil would last a very long time. In F100, 200, 220 and 229 turbo-fan engines, there were only a couple reasons to change the oil, scheduled maintenence, unscheduled maintenence or when I directed it.
I performed spectrometric oil analysis for 14 years and ran the busiest lab in the Air Force for 7 years. These engines could go their whole life without ever changing the oil (they are typically running at 11,000rpm most of the time). Not bad for something so critical that a 2-4 PPM increase in a wear metal was reason to ground the aircraft and investigate the cause.
In a car, the additives in the oil will get used up and the oil will get contaminated from combustion chamber blow-by. Who is telling you to change the oil every 3,000 miles? The filter can be changed every 3,000 miles, the oil every 6,000 and you still are not taking the synthetic oil to it's limits. And remember, oil darkening is from carbon, not wear, and oil does not start out an amber color, that is from additives.

I was told that all LS1s came lubricated from the factory as a sealed unit, and that i wouldn't ever have to change the oil for the lifetime of the vehicle. So far i've made it to 116XXX miles 
... ok ok... i'm kidding. I wanted to comment, but not just reiterate everything that's already been said.

nope. oil level stays relatively constant. i make sure of that. i think the oil just starts breaking down. regardless of which oil i use, lifters will start tapping at around 3-5k. probably could use new ones... but i'll get to that when it becomes a constant noise. i just use bullshit oil now. whatever is on sale at autozone lol. it's a v6, i'm not worried.

just ran castrol syntec for 10000 miles and the oilanalizer lab results came back great they recommended i run it 7000 more miles then send another sample
however i went ahead and swapped to amsoil so i can get 25K plus out of this oil change if the samples keep coming back correct
bottom line still stands that changing every 3K is just plain waistfull unless it takes a year to get that 3K lol or its a straight race car but daily driver it is just waistfull
