How long can you keep cooking oil after expiration date?

It is generally not advisable to use cooking oil past its expiration date. The expiration date is set by the manufacturer to ensure the oil's quality and freshness. Using oil beyond its expiration date may compromise its quality and lead to potential health risks. Over time, the oil can break down, develop off flavors, and become rancid. Additionally, the nutritional value of the oil may diminish over time. For these reasons, it is recommended to discard cooking oil once it reaches its expiration date.
