What triggers the change oil light ?
Does it get turned on by a number or hours or some kind of calculation of engine rpms? or is the some kind of sensor in the oil?
I'm just wondering cause, I put in Mobil 1 synthetic and a high milage filter to get me through the winter but I'm at around 3300 miles and my change oil light came on. wtf?
That oil should be good for at least 6000k right?

all dpends on how it breakes down
with stock oil it came on at 35XX, with valoline syn it came on at 3800
i ran royal purple and one time it came on at 4200, then next time it came on at 51xx, hell one time it came on around 5500.......everytime i had different driving techniques
when i put the 6.0 in with regular oil it would pop up around 3200
so gives you an idea

Found this at another forum...

This is from GM Tech Line.
How often should engine oil be changed?
- 3,000 miles (5000 km)
- 5,000 miles (8000 km)
- 7,500 miles (12000 km)
- 10,000 miles (16000 km)
Actually, all of these are correct, depending on operating conditions. Oil life is affected by many factors other than just miles driven. The type of driving, temperature, and engine load all play a part.
That’s why GM has developed the GM Oil Life System, an electronic watchdog that keeps track of all these variables and notifies the driver when it’s time to change oil. (fig. 1) We first told you about the GM Oil Life System in the March 2000 TechLink. Since then, the system has become standard equipment on nearly all GM products.
Briefly, the Oil Life System is programmed with a certain number of engine revolutions. As the engine runs, this number is reduced until it reaches zero, and the Oil Life light or message comes on. But there’s more. Operating the engine under low or high temperatures, and under high load conditions subtracts (penalizes) extra revolutions, so the light comes on sooner.
Changing engine oil according to actual need rather than an inflexible schedule provides several benefits.
First is simpified determination about when to change oil. No more decisions about “normal” conditions vs. “severe” conditions. Second is reduced operating costs for GM’s customers, who now have to change oil only when it’s needed. Third is minimizing the amount of used oil that must be disposed of. And fourth, engines will always be running with sufficiently fresh oil, for long life.
These benefits will be realized only if engine oil is actually changed as indicated by the GM Oil Life System.
Some customers “get it” when it’s explained to them. Others may be reluctant to deviate from traditional oil change interval charts. So, part of the responsibility falls on retail service people to help get the message out.
TIP: To help you do this, an IDL broadcast is being prepared. Consult the GM Training Program Guide and Schedule for “Understanding the GM Oil Life System” (PPS03.P1D).
