I think I should change my oil too. My 05 STi has about 2300 on her now.
One question (and excuse my ignorance), what do you mean by "regular" oil? I know and understand what synthetic is. Are you guys talking about getting them from the dealer or just any brand, as long as it's not synthetic, i.e. Mobile 1, Castro, etc...? Also should the filter be changed as well for this first oil change?
