I have a 1998 toyota camry, over 100,000 miles, Toyota is rebuilding or replacing my engine next week. The service personal were great. I gathter as much information about my car as possible. Was only asked to show at least service for each year. Naturally my records are not that good, but I did manage to find oil changes and services from 2001 to present. It was excepted and under warranty, I am getting my engine rebuilt. It was diagonised with the oil gelling problem.
