Kirks quote according to my father is pretty much a blanket excuse. Most if not all auto makers claim a qt of oil/1000 miles is normal oil use. No one is happy hearing it if they use that much oil but that's what they will hear.
ALL ENGINES USE OIL, just extend the OCI out far enough and you will know how much oil your engine uses. There is no such thing as a car that doesn't use oil. A more accurate statement about oil use would be I use no oil between changes. So in the case of a 6 month or 6000 mile OCI. If a person used no oil, an accurate statement would be he used no oil during his OCI.
