Consequently, does motor oil go bad in a car?

Under optimal conditions (stored in the original, unopened containers at moderate temperatures), motor oil usually remains stable for an extended period of time. That said, an engine oil's properties are best if it is used within two years.

does motor oil degrade over time? Over time, petroleum-based oils will degrade or break down from the heat and pressure inside the engine. As this occurs, the chemical composition of the oil changes and it becomes contaminated. After thousands of miles, petroleum-based oils are unable to protect the engine and must be replaced.

Considering this, how long can synthetic oil sit in an engine?

six months

How long will a quart of oil last?

five years. Just keep it away from long-term exposure to extreme heat, and keep it sealed up so it isn't constantly exposed to air and doesn't have the chance to develop condensation. Your oil should last longer than you think it will. If you have motor oil that you have no idea how old it is, just have a look at it.
