How Burger King has changed its frying oil
On October 2, 2008 Burger King said all of its US restaurants were cooking in trans fat free oil, using two proprietary three oil blends it never named publicly. Remaining menu ingredients were due to hit zero grams trans fat by November 1 that year. Source
In July 2007 Burger King said every US restaurant would be frying in trans fat free oil by the end of 2008. The company did not say at the time which oils the new blends would be built from. Source
Weeks after McDonald's made its move in July 1990, Burger King said its fries would be cooked in vegetable oil too, with the change finished chainwide that fall. Contemporary coverage is thin, so treat the exact month as approximate. Source

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 Burger King report card, or where it lands on the Seed Oil Index. See which chains fry in real fats on Tallow Watch.
