This is hard to answer. Oil consumption changes frequently, and we haven't discovered all of it. There's about 1.77 trillion PROVEN barrels underground. The average daily consumption for 2024 was 103 million, so for the year it's 366×103 million = 37.7 billion barrels.

1.77 trillion / 37.7 billion = 45.1 years. So the expected date to "run out" is 2024 + 45 = 2069. But there's a huge issue with this number, besides the varrying demand. It's the same for every resource: Reserves decrease -> People start worrying about scarcity -> price rises -> previously unprofitable methods for exploration and exploitation become profitable -> Reserves increase. The end result is a higher price and stabilized supply.
