Some accessories make changing the oil in your automobile easier.
The opening in the top of my engine ('99 Olds Alero) will hold a quart oil container, but it is not easy to pour without spilling, at least until the oil is able to drain from the container as shown in the photo.
Step 1: A Funnel Helps
The natural solution is to use a funnel But, the funnel cannot go far enough into the opening on the engine to be stable and support the oil container well. The container in the photo appears to be well supported, but it is also empty. In practice, the container and the funnel fall off of the engine.
