Just bougth a new Corolla and have a few questions. Does the Corolla come with "break in" oil like some Hondas? If not ... I was planning on changing oil at 1k miles. I'm undecided on M1 vs conventional. Only drive about 6k miles a year (95% city). So, at 6 months I'm lucky to have 3k miles and that seems a little wasteful to be replacing synthetic. Any advice?
