Hey everyone! This is my first BMW so I don't know if it's just me but, I feel like the 15,000 miles between scheduled oil changes is a little long. I know that BMW uses synthetic oil and what not but it would make me feel better to change it more often anyway. For peace of mind at the very least, and I figure it couldnt hurt right? Well, I have a 2004 325ci and I was thinking I wanted to change the oil say every 7500 miles maybe just once in between every scheduled maintanence. But, I dont want to fork over the extra dough for the dealers to do it, so I was thinking maybe I could learn to change the oil myself. So I would really appreciate it if anyone knew where I could get step by step instructions, and some helpful tips on what oil to use, how much to use and so on. Thanks a lot in advance guys! Just wanna keep my new baby in tip top shape.
