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.
What is the expiration date of motor oil?
There is no official expiration date on oil like we get on food. However motor oil is the same as tyres, they will last for a long time however they go past there best after 5 years. Does motor oil go bad sitting in an engine? In the engine, the oil will start to degrade over time yes.
Does motor oil go bad?
Although you can look at the expiration dates on the bottle, motor oil can also go bad just from sitting in a car engine for too long or when stored improperly. Under optimal conditions, motor oil should remain fairly stable. However, extreme temperatures, synthetic additives and oxidation all play a role in causing it to go bad.
How long does an unopened motor oil bottle last?
An unopened motor oil bottle lasts for approximately 5 years, or until the expiration date on the bottle expires. If the oil is already in the engine, you should follow the manufacturer’s schedule for how often it should be changed. It is usually every year or every two years. 1. Unopened on Shelf
What does unused engine oil mean?
Unused engine oil refers to motor oil that has not been used in an engine. The biggest indicator that your unused motor oil is bad is the expiry date. Unused motor oil will start to degrade and lose its effectiveness after a certain amount of time. Most engine oils will have an expiry date printed on the bottle.

Under optimal conditions, motor oil should remain fairly stable.
Does engine oil go past its best?
Yes over time the oil will go past its best. It will last long unopened compared to opened. However, engine oil manufacture state that oil will be at its best for 5 years. Does synthetic oil last longer than regular oil?
How long does synthetic oil last?
How many months does synthetic oil last? On average, synthetic oil lasts from 6-12 months. Depending on viscosity grade, some synthetic variants are more thermally stable than others and may extend oil life by a few more months. Ultimately, it depends on the different factors discussed in this guide.
Does motor oil degrade over time?
Does motor oil degrade if not used? Yes over time the oil will go past its best. It will last long unopened compared to open. However, engine oil manufacture state that oil will be at its best for 5 years.
How often do you change synthetic oil?
every 7,500 – 15,000 miles
Unlike regular car oil, synthetic oil is more refined which can lower friction, reduce engine sludge, and increase engine performance. It’s recommended that you change synthetic oil every 7,500 – 15,000 miles, depending on the vehicle and the brand of synthetic oil used.
What is the recommended synthetic oil change interval?
Manufacturers’ recommended synthetic-oil change intervals vary greatly. For the vehicles in Car and Driver’ s long-term test fleet, those intervals range from 6000 to 16,000 miles (and almost always include oil-filter changes).
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).
How many miles does synthetic oil last?
Some oil manufacturers claim their synthetic oils last up to 25,000 miles, but 10,000 to 15,000 miles is the average. As for synthetic blends, they typically split the difference between conventional motor oils (5,000 miles) and full synthetics (10,000 miles), so you may be changing your oil around 7,500 miles.
How many miles between oil changes is normal?
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.
