What is avocado oil? How is it different from olive oil?
Avocado oil is extracted from the pulp of avocados. If removed mechanically without chemicals at temperatures below 122°F (which is considered "cold pressed," although modern facilities may now use centrifugation instead of the actual traditional press), it may be considered extra virgin or virgin and will be green and somewhat cloudy. If processed further, it is considered refined (sometimes referred to as "pure") and will be yellowish and, typically, clear (see What It Is).
Avocado oil has a higher smoke-point than olive oil, so it may be preferred for cooking at very high temperatures and it does not have the bitterness of olive oil due to a much lower concentration of polyphenols. -
Does avocado oil have health benefits?
Although not proven, avocado oil is likely to be heart-healthy if replacing saturated fats, like butter, due to its high percentage of monounsaturated and polyunsaturated fats. It is also a good source of vitamin E, provides enough beta-sitosterol to potentially improve symptoms of benign prostate enlargement, and contributes modestly to lutein intake, which may reduce the risk of macular degeneration (see What It Does). 
Which are the best and worst avocado oils?
We tested eight extra virgin, refined, or ungraded avocado oils. Based on chemical analysis, one product appeared to include oil other than avocado oil and was, therefore, Not Approved. On taste-testing, another product tasted of rotten avocados, so we don't recommend it (see What CL Found). Among the Approved products, we selected a Top Pick for its pleasant, medium flavor and mild, buttery, and herbaceous aroma. It was more expensive than most of the products although not the most expensive. Use the Results table to compare the test results and price per tablespoon, which ranged from 21 cents to $1.13.
It's worth noting that good avocado oil is expensive, costing several times the amount of best extra virgin olive oils that we have tested (which cost about 25 to 35 cents per tablespoon).-
How to store avocado oil?
Avocado oil should be stored at room temperature and away from light, preferably in a dark-glass bottle or stainless-steel container. Avocado oil that is unopened should remain stable for at least two years if properly stored. It is not necessary to refrigerate avocado oil, even after it is opened (see ConsumerTips). -
Safety and side effects of avocado oil:
Avocado oil is generally safe and well-tolerated, although some people may have an allergic reaction, and consumption of large amounts could potentially interact with the drug warfarin (see Concerns and Cautions).
