What's the easiest way to turn off the Check Engine Light? (Oil Change Light)
I do my own oil changes and i dont know how to reset my check engine light. Any simple answers to that other than bringing it to the dealer?

And just to be clear you are talking about your Check Engine Light and not your oil change light, correct? You can turn off the oil change light by turning on the key without starting the engine and press the gas pedal on and off 3 times within 5 seconds.

there are also OBDII readers you can buy off the tool trucks(snap-on, matco, mac) ive got one and they are the greatest! you can read codes and it will break them down in to english.. mine cost me about 75 dollars, but its a plg and play. you can get some that are hundreds of dollars, but as the price goes up the amount of functions and things you can change go up as well!2006 gmc sierra 1500 z71

Still not sure which light is on?? The oil light should be reset with gas pedal. The check engine light would have specific codes like a P0123 or a P0456, etc. You didn't say if it had any codes???

There is a general CEL (Check Engine Light) for that year vehicle, and starting in the year 2002 (maybe before, but certainly in 2002) GM had the Oil Life Monitor system ready to go for many engines and some of the early systems had to be reset, while now they have internal sensors that automatically will determine that the oil has been changed. In the very-very early systems of this type they were just merely a count-down timer of sorts, with virtually no sensor activity at all. They are much more sophisticated now.
So based on the nature of the question, I think he's asking about his 2003 Silverado with the middle-version of the Oil Life Monitoring system. Since we're talking about a feature that I had on my 2002 Trailblazer, I'm surprised that I can't remember off the top of my head how to reset that. I think it was something simple like 1) engine off - put key in ignition, 2) turn to accessory - do not start, 3) step on gas pedal 4-time in rapid succession, 4) turn key to off position - then go ahead and start the engine.

I love this video for it's simplicity. I also love how the guy is smoking a cig while lecturing people about specific information, like he's the smartest person in the world. I'd have a word or two with him if he was smoking in my vehicle.
