How long can oil sit in an engine before it goes bad?
Simply put, the shelf life of conventional motor or “lube” oil is
up to five years
. It's not something that goes bad in a couple of months. It's impossible to predict exactly how long motor oil shelf life is because petroleum stability (how well it resists change in its properties) is situation-dependent.

Does engine oil break down just sitting?
Motor oil can only last for a certain period of time. That's why it comes with an expiry date. For this reason,
oil goes bad with time just by sitting in the engine
. Over time, it becomes less viscous thus less efficient in maintaining proper lubrication between moving components.

When the oil becomes thin, old, or poorly textured, you might hear the issue every time you drive. When driving with bad oil quality, your engine may make
a knocking sound

Is it bad to go 1000 miles over an oil change?
Some drivers push it an
additional 1,000 or
2,000 miles, but even changing your oil that frequently may be unnecessary. Depending on your car, you might be able to drive 7,500 or even 10,000 miles between oil changes without putting your vehicle's life expectancy at risk.
How many miles is it safe to go over your oil change?
It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of
5,000 to 7,500 miles
. Moreover, if your car's engine requires full-synthetic motor oil, it might go as far as 15,000 miles between services!
Can you go 10000 miles with synthetic oil?
Full synthetic oils will actually last well beyond 10,000 miles
. The lifespan of synthetic oil depends, but it's not crazy to see oils still working at 15,000 miles or longer. … Our standard recommendation is 7,500 miles for a normal vehicle based on the thousands of engine repairs we've seen over the years.

The real limit is probably
16,000 miles or more
. If one is fine with doing 6,000 miles on an oil change in 3 months, then 2 years should be fine too. Oil doesn't go bad sitting in the crankcase. Oil degradation and contamination is proportional to use, not time.
