What I got from this thread and other Oil Change threads. In writing, this is what I have planned. (Still waiting for delivery)
1K - Filter only change, PurolatorOne
5K - Oil and filter change, OEM filter + Mobil1
10K - Dealer (ToyotaCare)
20K - Dealer (ToyotaCare)
25K - Oil and filter change, PurolatorOne filter + Mobil1
30K and beyond - Whenever I can get to it.
for me its 5000 miles, I've said it before, I say it again:
Do what the experts do and not what the experts say: Car Care nut swears by 5000 mile oil change.
and my motto adopter from car care nut.
Oil is cheap, engines are not, and I can live with that.
I have heard a ton of times of engines damaged by not changing the oil on recommended intervals. I have never heard about a damaged engine because someone changed the oil too many times.
