i woke up this morning, not really thinking, started driving to wal-mart to have them change my oil. but i only made it a couple of blocks before i turned back home because i promised myself i would go at least 7.5k on this OCI of 4qt mobil1 10w30 + 1qt of delo 15-40, or when the maitenance light come on in the car, which is every 7.5k. the current oil only has 6k in it, and it still looking good, but the urge to change it is definately there. it feels very itchy because i have never gone intentionally this far between oil changes before. thanks to bobistheoilguy forum, i'm turning away from the dark side. >
