I saw another thread on this, but thought I'd make a new one. Maybe it'll get a quicker response.
I did my first oil change last night. First for the WRX and first ever for me. I had some problems, but you live and learn right?
I couldn't get the filter off because I didn't have a tool. It was getting dark so I just added new oil and called it a night. A friend told me that I'll have to do the whole change over again when I change the filter, which I'm doing tomorrow. So do I have to do a whole change? Or can I just change the filter? Will I spill any oil?
