What oil do other chains like Five Guys use?

Why the frying oil matters

Most fast-food chains fry in seed oils like soybean, canola, corn, or a blend of them, which are high in polyunsaturated fat (PUFA). A handful still use beef tallow or other stable fats, which are far lower in PUFA. The oil a kitchen fries in is the single biggest driver of how much seed oil ends up on your plate. See the full breakdown on the Five Guys report card, or where it lands on the Seed Oil Index. See which chains fry in real fats on Tallow Watch.
