After opening, the shelf life decreases. Generally, an opened bottle of peanut oil lasts for around six months to a year. To prolong its life, keep it tightly sealed and store it in a cooler environment, away from direct sunlight.

- Strange Taste: Expired peanut oil can impart a bitter, unpleasant taste to your food.
