Does synthetic motor oil degrade over time?
Synthetic oils can easily offer double the service life as their chemical composition does not break down over time. Several manufacturers have taken advantage of this and supply synthetic oil in their vehicles from the factory to extend oil-change intervals and extend engine longevity.
How long can you keep unused motor oil?
Simply put, the shelf life of conventional motor or “lube” oil is up to five years.
Does synthetic oil have an expiration date?

Synthetic Motor Oil Myths
If there is a spot where oil could leak out in your engine, then synthetic oil is more likely to leak than conventional. However, synthetic oil would not cause the leak. You can’t switch back to conventional oil: Once you switch to synthetic, you are not bound to it forever.
Does synthetic oil break down with age?
Your motor oil is the only thing providing a protective element between those moving parts. Unlike synthetic blends or conventional oils, fully synthetic oils won’t break down and will protect your engine for longer—sometimes as much as 250,000 miles.
Can I change oil every 2 years?
Simply put, as a general rule, manufacturers recommend that you change the oil for a gasoline engine every 10,000 to 15,000 km, or about once a year for “regular” usage (frequent but not intensive) or once every 2 years if used less frequently.
What can I do with leftover engine oil?
The best way to store used oil is to put it in an air-tight container that can be sealed with a screw on cap. Once you’ve done that, you can take it to your nearest recycling facility, auto-store that offers recycling, or in some cases, even schedule a pick-up.

Does motor oil degrade if not used?
Yes, there is a short answer to this question. There is a limit to how long motor oil can last. This is why oil goes bad with time, just by sitting in an engine for a while. Over time, it becomes less viscous, thus less efficient in maintaining proper lubrication between moving parts over time.
What is the disadvantage of synthetic oil?
Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.
Can you mix synthetic and regular oil?
So, in the end, conventional and synthetic oils are comprised of the same, compatible components – it’s just that the components in synthetics are much higher quality. While you can safely mix synthetic and conventional oils, you’re doing nothing more than diluting the performance of the synthetic oil.
Can I put conventional oil after synthetic?
