Once opened, Nut oils keep about 6–8 months in the fridge. Unopened, they keep about 6–12 months.
6–8 months opened in the fridge, against 6–12 months sealed in the pantry. Green is what this situation leaves you; husk is what it spends.

About 6–8 months refrigerated at 40°F (4°C) or below, according to USDA FoodKeeper v128.
Nut oils 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. Those are the general signs for baking & cooking — USDA FoodKeeper v128 publishes no spoilage note for Nut oils specifically. Never taste something to test it — when in doubt, throw it out.
