Which oil lasts longer when frying potatoes?
Quality parameters during deep frying of avocado oil and extra-virgin olive oil

Surprising Findings
Avocado oil, often marketed as a premium, ultra-stable oil, degraded slightly faster than extra-virgin olive oil under frying conditions.
Many influencers claim avocado oil is superior for high-heat cooking — but here, olive oil outlasted it by 3 cycles despite being less refined.
Practical Takeaways
If you reuse frying oil, stop after 10 uses if using avocado oil, or 13 if using extra-virgin olive oil — don’t go beyond that to avoid harmful compounds.

When you fry potatoes over and over using avocado or olive oil, the oil gets more acidic, more oxidized, and loses some of its natural antioxidants.
Both avocado oil and olive oil can be reused many times for frying before they break down enough to be considered unsafe by health standards.
Avocado oil breaks down faster than olive oil when reused for frying — it hits the safety limit for bad compounds after 10 uses, while olive oil lasts 13 uses.
When you fry with these oils over and over, they react with heat and moisture and start breaking down into chemicals that signal the oil is going bad.
Both oils can be reused many times before they break down enough to be considered unsafe by health standards.
