Once opened, Oils (olive or vegetable) keep about 4 months in the fridge. Unopened, they keep about 6–12 months.

About 4 months refrigerated at 40°F (4°C) or below, according to USDA FoodKeeper v128.
Oils (olive or vegetable) are shelf-stable at room temperature: cool, dry pantry, sealed — refrigerating after opening is optional and mainly preserves quality. Refrigerating it mainly preserves quality rather than safety.
Look for: A rancid, paint-like, or musty smell; Clumping, or moisture in something that should be dry; Insects, webbing, or larvae in the package; Faded colour or a lost aroma. Never taste something to test it — when in doubt, throw it out.
