I know the standard milage that traditionally you are "supposed" to run for oil was 3000. Of course with today's engines and today's oils you can go longer than that pretty safely.
For me I've done a lot of miles so I always just looked at miles and never worried about the "months" part of the equation. But now that we are using my wife's car much less - I'm beginning to wonder - how many *months* do y'all feel I should go before I would need an oil change. 2010 Kia Optima - approx 85000 miles - running Quaker State Defy 5w-30. (at this point valvoline maxlife also looks like a good possibility)
