Oil Change Interval

I see a lot of questions on Yahoo Answers! about oil change interval. Some people are giving out poor advice about intervals, what kind of oil to use(synthetic vs. mineral). Here's a nice article from Yahoo Auto's that's good read. Personally I shoot for the 3000 mile change between oil and filter change. I used to be lazy about in my younger years but now since vehicles aren't cheap and and I need our family cars to last longer with fewer repairs(hopefully). I've become more religious about it and encourage other's to do the same. I've got my sister on the ball with hers along with my wife's car. I could almost open a business with it. Anyway here's the article. It's a good read.
