sadly, your motor oil, even when unused, losses it's lubricating properties over time. Over the course of a year, humidity, temperature changes, and yes, even ground level ozone can alter the chemical makeup of you oil.

I've heard 3 months as the rule, but 6 doesn't seem all that bad. 1 year? to each his own, but at 13k to replace a motor, if you're going to gamble, play it on the safe side.
