Lea, I notice that you got your boyfriend to do it for you- I personally couldn't be stuffed to change my or my girlfriend's car's oil, I have better things to do with my time. But more importantly, as BMW//MPOWER says, more frequent oil changes have no real benefit in today's modern engines and the other things done during the oil service are often just as important.

PS how did you dispose of the oil? It's quite toxic and can't just be poured down the drain.
