Examples of gluten-free oils include vegetable oil, sunflower-seed oil, olive oil, and oil. However, any oil could potentially inherit contact with gluten during manufacturing processes. Therefore we always recommend reading labels and trusting certified gluten-free products, mainly if they include additives or flavorings. Reach bent manufacturers if you've got any questions.

While the oil itself is usually gluten-free, when ordering items that are fried in oils at restaurants, make sure to ask if the kitchen uses a fanatical fryer for gluten-free items, as some foods cooked in oil might not be gluten-free (such as breaded meats) and thus would cause issues with cross-contact.
