I just got my new baby ('06 Impreza 2.5i), and I'd like to keep it for a long, long time. In addition to the required break-in period (nothing over 4000 rpm for the first thousand miles), I've heard from some people that it's a good idea to change the oil and filter after the break-in period is done. The book makes no mention of this, so I don't know who to believe.
Additionally, I want to switch to synthetic oil as soon as possible, but I've heard warnings to use the dino stuff for the first 5000 or so miles. Your opinions on this?
Finally, the manufacturer states the oil should be changed every 7500 miles. From other 2.5 n/a owners, what oil change interval do you use?
Thanks in advance, from someone new to the Subaru world.
