I Always Threw Away the Oil Drain Plug: A Colleague Told Me What It Was Really For…

Why This Annoying Oil Bottle Plug Actually Matters

This type of oil bottle stopper used to drive me crazy. Sometimes you have to yank it out hard and fast, and that often leads to oil splashing or spilling. Even worse, the little ring can snap, and then opening the bottle becomes a real hassle.

The Simple Trick Most People Miss

Here’s what I learned: the stopper isn’t just meant to be removed—it’s designed to be put back in the bottle, but with one important step first.

Before inserting it again, flip the plug upside down.

How to Reinsert the Plug Correctly

Follow these steps:

  1. Turn the plug over (upside down).
  2. Push it back into the bottle neck.
  3. Press it down so it locks into place between the grooves/slots.

Because the plug is not perfectly symmetrical, it will always leave a tiny opening once it’s seated properly.

What the Small Gap Is For

That small gap is the whole point: it works like an oil dispenser. Instead of pouring out too quickly, the oil flows in a controlled, thin stream—making it much easier to measure and preventing messy spills.
