I drove my new 2004 Corolla 5spd gradually harder and was hitting redline now and then by the time I had just 200 miles on it. I switched to Amsoil synthetic oil at 2250 miles and change it every 5500 miles. Now with many mods, and 40000 hard driving miles flirting with the 6500 RPM rev-limiter a few times a day, the oil level might go down about 1/8" on the dip-stick between changes. An new engine has to be GRADUALLY driven harder and up to gradually higher RPMs, and be subjected to all operating conditions, and not sustained at low or constant speeds. Full power up to redline should be achieved before too long for a true and complete seating and break-in.
this guy says 6500 rpm but I have 4 speed auto- cuts off at 6k so Im not sure what it is.
