The limiting factor in changing your oil is the filter. Most synthetic oils protect well into the 10K mile range and beyond but your filter may clog before then. I haven't been able to find the bigger OEM WRX filters (made by Purolater as Nick pointed out). They made it smaller so it wouldn't absorb as much radiant heat from the header but mine are heat wrapped...

A larger filter should be able to last longer without clogging so I think I'll be switching to the Mobil-1 M-110 or M-108 in the future. The M-110 is twice as tall though and I wouldn't want to risk scraping it on something. That would suck. Amsoil supposedly makes a good oil filter too.
