See full version: Does Motor Oil Expire
So whilst motor oil manufacturers say we should responsibly dispose of oil after a few years they all stop short of saying that the oil does actually expire. Clearly, there is a vested interest in their future sales here so to get to the truth about oil we need to drill down deeper.

Separation of the additives from the oil is one sign the oil may not work well. If you notice clumps, gel lumps, or the oil is thick and sticky, then it probably isn’t safe to use in your car. You should also check the colour for haziness or a milky look, which could signify overexposure to moisture. If you don’t notice colour changes or consistency changes, then consider your oil safe to use.
We recently spoke of how engine oil affects your fuel efficiency. Let’s have a look at the shelf life of engine oil.
The answers to these questions vary based on the type of oil you buy and where you store it.
The best way to tell if the stored oil is still good for your engine is to check the condition of the oil before you put it in your car. If you stored it in a cool dark place, where it wasn’t at risk for oxidizing, then it’s probably safe to use it. However, if the area you stored the oil had frequent temperature changes or exposure to excess moisture, it could affect the condition and efficacy of your oil.
If you buy a big box of engine oil and store it for a few years, it’s probably good to use. However, if you buy the oil and then purchase a new car, you need to check if the formula you purchased meets the current standards. Car manufacturers consistently update the way they manufacture engines and the science behind the way vehicles operate. here

Subsequently, one may also ask, how long can you keep 2 stroke oil? more
The basic oil is good. The oil in a 2 cycle is blended with gas to help lubricate during spark plug firing. It does not sit around a bearing for years. This might not change much in 1 or 2 years, but if the oil is 5 years old - you can garantee it's not the 'optimal' formula for current blends. more
