Oil change time... yay!

[YarisFan007]

I'm getting different feedback from everyone on when to have your 1st oil change.

I heard it's good to have it done once you reach 3k. Others say its ok to have it done @ 5k. I'm about to reach the 3,000 mark and i noticed the "Maintenance required" light lit up this morning. I'm assuming the "Maint reqd" indicator automatically lights up when it knows it requires proper maintenance and/or an oil change and that this is a standard feature w/ most cars.

So, what do you think? Should i change my oil @ 3k? or 5k?

Thanks in advance.
