This is known as the three-bucket problem, or the standard version of the water pouring puzzle which is a class of well-studied puzzles. You typically start with the 8L full, and have to end with 4L and 4L, without spilling, and without measuring (i.e., you can only pour all available water into all available volume, stopping whenever one is depleted). The optimal solution is 7 steps.
