This Kirkland Pure Olive Oil comes in a practical two-pack, with each bottle containing over 100 oz of oil. You’ll find this a cost-effective option, especially if you do a lot of high-heat cooking like frying or roasting, as pure olive oil generally has a higher smoke point than extra virgin. The large quantity ensures you’re well-stocked for various culinary tasks.

While it’s a good value and suitable for high-heat applications, note that ‘Pure Olive Oil’ is a blend and lacks the nuanced flavor and health benefits of extra virgin. It’s a workhorse oil for everyday cooking where intense flavor isn’t the primary goal. If you need a budget-friendly, high-volume oil for frying and sautéing, this twin pack is a solid choice.
