If you ask does canola oil go bad, then the answer is yes, this oil will go bad the longer it is stored. However, in general, canola oil lasts a long time, canola oil lasts between 1 year to more than 2 years. How long it lasts in storage depends on when you open it, and how often it is exposed to air. One sign that canola oil has gone bad is that it smells rancid. If you find it with a rancid odor or an unpleasant odor, then it is likely that it has rotted.

But unfortunately we can’t see clearly or for certain how long it lasts. So the best-to-use date is made and printed on the bottle. The expiration date is not the date when it goes bad but it is the time limit for the quality of canola oil to decline.

So, what is important for us to know is how to tell if canola oil has rotted or has a rancid smell.

How to Tell if Canola is Bad?

Here are several ways to know if canola oil has gone bad. If you find any of these indications, then just throw away your canola oil.

Bad smell: If your canola oil smells like paint or like detergent or some other strong odor, then that is a sign that the canola oil has gone rancid and you should not use it again. Canola oil should never go rancid as it is used in dishes.

Color change: Signs of canola oil spoilage can also be seen from the color change. Canola oil is pale gold in color and clear. If the color has changed to black or brown then it has rotted. But if there is only a little crystallization and the color changes only slightly, then this is not a problem.

Mold or microbial growth: This oil will not mold as long as you cover it properly, but anything can happen, this condition usually occurs when the bottle cap is not closed properly.

Bad taste: This is another indication of canola oil spoilage. If you notice a strong, sour taste, it means your oil is not good. Canola oil should have a neutral taste. If your oil no longer tastes neutral, then it indicates that it has gone bad.

This is a guideline and indication of spoilage in canola oil, this formula also applies to other oils such as sesame oil and grapeseed oil.

The spoilage that occurs in this oil is most likely due to not closing it tightly or because it is contaminated with outside air.

How Long Does Canola Oil Last?

Basically, canola oil does not expire, but over time the quality of this oil will decrease. If some time ago it was fine and today it is rancid, this could happen to canola oil that you have stored for a long time and so you opened it and didn’t close it properly.

So, the best-by date printed on the bottle can help a little even if it is not a sign that the oil has gone bad. Usually canola oil can maintain its best quality for several weeks or months after the best-by date.

If your canola oil has expired, try checking how long it has been around. If it’s only been one month or two months, then this is still a good possibility. But if it is more than two months from the best-by date, try to pay attention to signs of spoilage. See whether you are still comfortable using it, whether there is an unusual smell or other signs.

Check your canola oil to see if it still meets the expiration date in the table above. If your oil is too old from the date stated, then you should avoid it. But if it’s not too long since the expiration date, it’s possible that canola oil can still be used.


If it has reached its expiration date, check whether you are comfortable with the canola oil. If it’s safe, chances are you can use it. However, if you see it is not safe, then just throw it away and no longer check for signs of spoilage.
