My sister's neglected 2005 Toyota Sienna with 249,859 miles:
Out: Castrol Magnatec Synthetic Blend 5W-30, Champion COS3614 Filter
In: Napa Synthetic 5W-30, Champion COS3614
15,290 miles and 14 months on OCI (yes, I reminded her multiple times...)
Oil was just barely registering a tiny bit on the end of the dipstick. About 1.5-2 quarts low. It's possible I changed it sometime in between this last OCI and the prior and forgot to note it, but I highly doubt it. Just goes to show how good that Toyota 3.3 is. It still runs like new and doesn't leak, it just consumes a little bit. Used full syn this time since she always goes too long.
