I just realized that for the first time I can actually contribute to this thread I started almost 16 years ago!
My Civic has 151,000 miles on it, I bought it in 2011 with around 80,000 on it and I've done one year oil changes since I got it (OCIs varied from 3k to over 10k) I started out using Toyota 0w20 for the first couple of years, then Mobil 1 0w20 for the few years in the middle and for the past two years I've used Pennzoil Ultra Platinum 5w20.
