Most manufacturers and mechanics that use synthetic oils are saying that 7500 miles between an oil change interval is completely normal for just about every vehicle in which they are used. Depending on which type is being used, you may be able to go 10,000 miles (or about one year) before changing your synthetic oil.
How often should you change your engine oil?
There is a permanent thickening of the oil. Some automotive manufacturers are backing down on oil change intervals to 5,000 miles or less and some advocate changing the oil at least every 6 months as well. I think this is because of the tendency for oils to thicken in very hot engines (not ambient conditions, just hot engines).
Can car oil last 2 years?
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.
How long does motor oil last?
The motor oil’s shelf life recommended by each manufacturer varies, though. For example, Mobil expects industrial or motor oils to last for five years if stored properly in the original container. Meanwhile, Total, another leading manufacturer, says motor oil should be disposed of after only two years if not used.

What happens if you don’t change car oil for a year?
When oil has not been changed for a long time, it will begin to gel or solidify in an engine, eventually turning into sludge.
