its proven!
DO NOT TRUST GM OIL LIFE MONITORING SYSTEM!!.
I have this on my 04 silverado z71, and what a worthless computer program this is. It does not monitor oil quality, i think it monitors engine hours. I personally do all my own oil changes based on mileage. i have had many instances were i have done an oil change, and the friggin change oil light would come on 2 or 3 weeks later with only 7 or 8 hundred miles on fresh oil. BEWARE!!!!

I know you all have a mind set on changing oil so promptly at 3000 miles. I work at Honeywell which makes fram, penzoil, mack filters along with marine applications. We test our 3" filters on pulsators, which is pulsated at 0-60 psi every second. Most filters go well beyond 60,000 pulsations. OE requires that the filter last 27,500 pulsations. There is no real relation between pulsations and mileage, but each pulsation acts as a massive acceleration. Mileage wise, probably well over 10,000 miles. Really, you could change your oil and not the filter but no one ever does that. The only reason you would need to "change your oil" is when the oil breaks down too much. This is what your oil life system does. If you change your oil before your oil life system tells you to you are just an idiot. And I may be wrong, but I believe Mobil 1 comes in your car. At least there is a Mobil one emblem on top of the oil cap which would make me believe that. Just a word of the wise. I have an adobe file which I can get when I go back to work on monday that says the exact same thing. It is all about how you do not need to change oil every 3000 miles as long as you use a good oil.

I would like to see documentation proving this if it is prooven!

Were you resetting it after each time? Also, there comes a point where you should use common sense.... If you are at 10,000 miles and your oil change light hasn't come on yet, I would change my oil. If it came on at 500 miles, I would not change it. Just use what god gave you when you were born, a brain.

YAY! i'm estimating at like 7000 it'll be due for its first change
I will reiterate and suggest anyone who does not trust the oil life system take 2 minutes and physically check your oil and see if it's dirty. I have been verifying my oil is still all along. I've got 2500 miles on the car and the oil still looks good. The computer claims 63% life left. It seems accurate so far. I anticipate the oil will indeed last between 5-6K. It DEFINITELY will not be needing changing at the godlike number '3000 miles'.

At first I thought about using the 3000 mile benchmark just because it's "easy", but I think I'm going to do the first change when the oil life system says I have 50% oil life left - I think that'll give me some idea of how to adjust my oil change schedule based on what the computer says.
If this car behaves like my '98 Cavalier did, I shouldn't "have" to change the oil every 5000km. There were times I let the Cavy go for 7000 - 8000 easily and had 0 problems with my car when I sold it in May of this year. I'm still undecided on the oil life system though because I don't want to take a chance that it is inaccurate and negatively affects my car.
I think for at least the first oil change I'll be going in after 5000km to dump the oil and change the filter just so I can start from scratch and make sure there are no filings, etc. building up in my engine. I would assume with the new machining and break-in techniques used at the plants that this should never be a problem anymore but there is always that chance.
As for my oil life system, I'm at 4600km and my oil life is at 67%, so approximate calculation, driving the way I am now the oil "should be good" (no way in hell I'm gonna push this) for 10,000km or so. I've mixed my driving between in town and highway for the last 2 months since I bought the car to push it along breaking it in so the oil life monitor could be right since nearly half of that is highway driving at 100 - 110 km/hr.

but our oil gets changed from the factory after the motors are broken in, so trust the DIC
im at 4000 miles, and im at 50% oil life

Considering your car, you are probably right, all though it is unneccassary to change it more often than it requires.
But if you havn't been living under a rock for the past 20+ years, you would know the global situation with oil and gasoline and have an obvious answer to your nonquestion.

Oh really.... is that what he said!! LOL I thought that was funny when I was reading it. Sorry. For the guys who have already changed their own oil on their SS/SC there should be a How To... on this just because i'm sure no one wants to go and spend $80.00 everytime they get their oil changed. now from my understanding our cars use Mobil 1 oil... 6.5 qts of it. Now I went to AutoZone today to check on the price of it and it was about $5.00/qt. I also saw that there was another Mobil 1 oil version... a 15,000 mile one
While were all on the topic of oil here, what thickness of oil do you guys use? I know the manual asks for 5w-30, however, I've heard that some people will put a little thicker in during the summer because of slightly higher heat. Also, should I go synthetic or old school?
My DIC says I have around 43% oil life remaining with 4200 miles on the car....I just hope the DIC knows what it's doing heh

2) I always go with the stock thickness. If it comes with 5w-30 then it always gets 5w-30 regardless of season, temperature etc.
3) With the DIC it's a good idea to get a baseline oil change on your car. Pick a milestone on your DIC (I'm going for 50%) and change the oil. Check and see how much dirt is in it, the color of the oil, consistency, smell, anything that will give you a clue as to how much the oil had broken down and how much dirt gets into it from your everyday driving conditions. Then do your calculations from there, if you change it at say 3500 miles and it looks good then you should, if you drive under basically the same conditions, need to change the oil every 7,000 miles or so, assuming your driving conditions didn't change drastically. This does two things: first it makes sure you're not getting too much dirt through your engine...the oil may make it to 7,000 without breaking down but there may be so much dirt in it that you end up damaging the engine (the DIC computer doesn't calculate for dirt in the oil) and secondly I know of people who have had their oil sensor malfunction and the DIC never said they needed an oil change when really they were way past due for one. If you do the baseline change, and then suddenly you're at 8,000 or 9,000 miles and the DIC is still saying it's not time for the oil to be changed, you know there might be a problem.
I'm at 4600 miles on my car and i checked the oil and it looks clean still just a tad dirty but it's not bad at all my DIC says 47% just like everyone else is saying I sure hope that DIC is right.
Thanks for the info...I picked up some mobile 1 synth. extended life earlier today....
Now for the stupid question...where is the oil filter located on the 2.2L? I'm just not sure where to look, mainily cuz I haven't had to replace a filter like this yet....

check your dealer for the filter. mine was 5 bucks for the hengst/ac delco filter that came in the car, compared to 7 for hte fram at walmart.
don't you love how the owners manual and service manual both say the 2.0 only takes 5 qts?

Unscrew the oil fill cap and then pull the cover up. It is held in by two clips. The filter is to the right of the manifold. I takes about a 1 inch socket I believe. There are pics on this site but don't remember where at. I took mine in for the first oil change at Jiffy Lube and went to McDonalds and upon arrival back, they couldn't find the oil filter either. They felt stupid when I pulled the cover off. So don't feel bad, even the "certified technician" don't know everything.
I didnt have to change my oil til about 10000 miles according to my DIC. It was a real dark brown color, so it "looked" OK. I used to change every 3K but thats real expensive and like a lot of people have been saying, trust your DIC its there for a reason. A 32MM socket with extension makes it real easy to get to your oil filter behind the supercharger. And I bought the Mobil-1 and Fram filter at Wal-mart for $45 (2 5quart bottles) because I had to put in 7.5 quarts! 5 quarts my A@#!
How could GM argue their DIC's are wrong? Trust your DIC!
