well..... i took my car to the homestead miami speedway the day after getting the 1200 mile service

did a full day of track time, each shift at 8000-8200 RPM. after the track day it said i had 5000 miles till my next service. since then it went back up to 12000

from my racing experience, the harder you break in an engine, the faster it goes.
