What should you do if you overfill the oil in your VW?

Oil pours into an engine.

While overfilling your engine oil may not sound like a big deal, it can actually cause serious damage to your internal engine parts. An overabundance of oil can actually lead the flow of oil to be cut off, which can eventually lock up the engine. So what should you do if you put too much oil in your vehicle?

The first step is to verify that your oil has indeed been overfilled. Check the oil by parking the car on a level surface and going through the dipstick procedure. If the oil is indeed above the fill line (as verified with a few checks), then it would appear your engine has been overfilled.

In this case, the next step is to drain the excess oil from your vehicle.

How to Drain Excess Oil from your Vehicle

What you’ll need:

  • 3/8-inch drive socket wrench
  • Plastic oil pan
  1. Crawl beneath your car and locate the oil plug. The oil plug is a large bolt at the bottom of the oil pan. If you have difficulty finding it, consult your maintenance manual for guidance (this can likely be found online).
  2. Place the oil pan underneath the oil plug.
  3. Using the 3/8-inch drive socket wrench, loosen the oil plug until oil begins to trickle out. Keep loosening it however much you feel you need to to drain your excess oil. However, be careful not to loosen it too much, as this can cause a rush of oil to pour out.
  4. Pause your draining periodically to check the oil dipstick. Stop draining once the level becomes even with the “full” mark.
A hand unscrews the oil bolt underneath a car and allows a stream of oil to drain into a yellow oil pan.

What happens if there’s too much oil in your car?

Having too much oil in your crankshaft results in the oil becoming aerated and whipped into foam. This creation of foam can halt the oil flow and drop oil pressure. Due to this halted flow, your engine will not be receiving enough oil. As you can imagine, this is not ideal.
