The situation:

Bone stock Si

Engine replaced with used OEM motor "with less than 80k on it" with 160k on the clock

Now reaching 200k miles, need advice on what preventive maint. to do to 'celebrate' getting it to 200k and make it to 300k - what do have done, in order of importance/neglect, as well as what to expect as far as cost for each.

I've owned it since early 2014 and put the last 90k miles on it with religious oil changing and very little else. Struts replaced at 150k, new plugs at 160k (at engine replacement) and that's all I've done.

Now what?

 

Well sorry nobody has replied. I'm fairly similar, bought with 115k on it, now up to 130 a year later. Replace the downstream 02 sensor, cheap will cause check engine light. Also replace the gas cap, similar check engine light. Other items can't offer an opinion.

 

have you change the trans oïl at all? you could also check your direction, spark plug, link it.. all that good stuff?
