Oil usually comes in a clay flask that holds 1 pint. As an action, you can splash the oil in this flask onto a creature within 5 feet of you or throw it up to 20 feet, shattering it on impact. Make a ranged attack against a target creature or object, treating the oil as an improvised weapon. On a hit, the target is covered in oil. If the target takes any fire damage before the oil dries (after 1 minute), the target takes an additional 5 fire damage from the burning oil. You can also pour a flask of oil on the ground to cover a 5-foot-square area, provided that the surface is level. If lit, the oil burns for 2 rounds and deals 5 fire damage to any creature that enters the area or ends its turn in the area. A creature can take this damage only once per turn.

You can douse a creature, object, or space with Oil or use it as fuel, as detailed below.

Dousing a Creature or an Object. When you take the Attack action, you can replace one of your attacks with throwing an Oil flask. Target one creature or object within 20 feet of yourself. The target must succeed on a Dexterity saving throw (DC 8 plus your Dexterity modifier and Proficiency Bonus) or be covered in oil. If the target takes Fire damage before the oil dries (after 1 minute), the target takes an extra 5 Fire damage from burning oil.

Dousing a Space. You can take the Utilize action to pour an Oil flask on level ground to cover a 5-foot-square area within 5 feet of yourself. If lit, the oil burns until the end of the turn 2 rounds from when the oil was lit (or 12 seconds) and deals 5 Fire damage to any creature that enters the area or ends its turn there. A creature can take this damage only once per turn.

Fuel. Oil serves as fuel for Lamps and Lanterns. Once lit, a flask of Oil burns for 6 hours in a Lamp or Lantern. That duration doesn’t need to be consecutive; you can extinguish the burning Oil (as a Utilize action) and rekindle it again until it has burned for a total of 6 hours.
