Oil color is nothing to worry about at all. I'd like to see all the "stories" from this one guy who claims they keep seeing problems with the OLM at the dealerships. I call BS. The GM engineers created an awesome piece of technology in the OLM and it works.

If they are seeing a lot of engine failures, then they need to look at their engines; not the oil length in service or the OLM.

Would an aftermarket cam have any affect on oil life?

Changing my oil tomorrow. 54% last I checked before I drove earlier, probably going to be around 50-52% tomorrow before the change.

I ignore the sensor AND the 3/3000 rule. I dont drive the car enough for the sensor to tell me to change it but I also feel that 3 months/3000 miles is over kill. I change it when I feel its time. After it sits a long time (winter), before a long trip... whatever.

I think in the 1.5 years (18,000 miles) I've had the car, its been changed like 3 or 4 times.

I have OLM in my 03 Avalanche also. I let it go to zero everytime and it varies between 4800- 5200 miles. I now have 39000 on it and have not had any problems. I used to do every 3000, but now usually do 5000 on my other cars. My neighbor has a 90 Dodge pickup he bought new, it has 226000 on it and has never changed the oil only added when low and it runs good and doesn't smoke. I think oil can go a lot longer then we think it can.

226,000 miles with never changing the oil? I would hate to see what that looks like under the valve covers.

Exactly. One of the biggest wastes of money I have always heard and read about regarding cars is changing your oil before it's necessary. Yes you can do it if you want to spend the money, and of course racing is different, but you are just spending money.

There is a ton science in the OLM calculations. Trust me, with GM having a 5 year 100,000 powertrain warranty, they would know almost immediately if there were any concerns. And replacing an engine is THE highest cost warranty item (and it doesn't happen very often). So it's not in GMs interest to make this up.

GM tried to market it as an environmental improvement (less used oil in the environment), a cost savings to the owner (less changes needed) and simply using less oil (a good thing these days it seems)

Of course this impacts the oil change shops and I always get the "oh, this oil is verrrry dirty. You need to change it more often." Well pretty much any oil in a car driven will come out black. I think my motorcycle which gets driven very infrequently, might have a tint of the original gold when I change it.

Also, regardless of the OLM, change your oil at least once per year.

And that being said, Mrs. Number 3 drives her Malibu 100 miles a day.......allllll highway. The OLM would let me go well over 10,000 miles and even I can't go that far, and I trust the science.

Tribology..............look it up.

My car has just under 6000 miles and she will be getting her 4th oil change, the first was @ 560 miles, 2nd @ 2000 miles, third @ 4000 miles and this next one I was going to wait till 7000 miles but she is getting a cam change so they will change the oil then. This was a little excessive but I do run mine hard 1/2 the time I drive her and oil is cheaper than a new engine!!!!

I noticed the same thing, my oil too is dark color after the harsh winter we had.
Have almost 4k miles since I changed it last August. I don't think I'll go past 5k either no matter what the monitor says.
Didn't think the Mobil1 would do that.

Hey guys I'm a BMW tech and just thought I'd throw in my .02. I've been at the dealer where BMW runs castrol syntec for upward of 15000 miles between oil changes. I've seen the condition of the oil when it comes out of an engine with that many miles and I can tell you I wouldn't want oil that dirty in my engine. The shop we work at now we change the oil every 5000 mi and the oil is in noticeable better condition (still using syntec) and while it's not beyond it's life, I feel that 5000 miles is a good interval for keeping an engine clean with a good qualiy oil. I ran my ls1 z28 clear up to 210k mi and still running strong using syntec and changing every 5k mi. I now have 600 miles on my ls3 which I plan to do a breakin oil change at 750 mi using castrol edge and changing oil every 5k mi.

Also in regard to the cam affecting oil life. The cam replacement itself if left with a stock tune won't affect oil life. What will affect oil life is when you tune the ECM, as this usually leads to running the engine richer, and depending on how rich the tune is you may need to change your oil more often. And of course if you run the car hard consistently, all of that abuse and high temps will burn up the oil faster and also require more frequent changes.

There is absolutely no way you can tell how phisically/chemically "dirty" the oil is by looking at it. The only way is to send a sample in for analysis. Oil turning dark has zero validity on its real condition.

If you run Mobil1 or a true synthetic and change it at 3000 miles you are wasting money and resources.

I changed mine at 1000 miles the first time because being a new engine I felt there would be metal particles in the crankcase. After that probably 3-5 thousand miles. Take care of the baby it's good insuranace.

Mine was dark after 600 miles. With other cars I noticed it would turn dark when it got close to 3000 or the motor wasn't running correctly. With the Camaro it seems as if the synthetic oil will turn dark as soon as the engine starts up.

Without reading all the other posts.. I was to understand the engine oil monitor is based on how many times the motor turns over.. So the harder you drive the faster it will say it needs changed.

Edit: I did my first oil change at 400 miles. Lots of metal was in the filter.

Same here. Coming up on my 6th oil change at 12000 miles, that includes a change at 500 and 1500 miles during break-in.

You didn't think Mobil 1 would do what? Work? Oil turns dark. Sometimes real fast. Oil color means nothing. You guys who make assumptions about your motors performance and change your oil due to color after only after few thousand miles crack me up.

If you say anything about your oil longevity without a used oil analysis, you are speaking out of your ass.

Wish I lived near ya. I would take your old oil and run it another 3000 miles minimum.

Do not rely in what the mileage on the bottle says or what your gauge says, get a feel by checking it yourself. If it looks like it needs to be changed use.common sense and change it.

There is no "look" to signify that oil needs to be changed.

you change the oil and filter to remove contaminants and sludge. You dont have to.change it, but oil is meant to be chaned when its dark. That's a hint its burned and full of contaminants. I ran my old dodge neon to 300k miles and never changed the oil..inside of the motor and fuel mileage was a subtle hint that I didn't
