As a car owner, there’s nothing more frustrating than noticing that your vehicle is leaking oil after an oil change. It’s a common issue that can cause concern and worry, especially if you’re not familiar with the inner workings of your car’s engine. In this article, we’ll delve into the reasons why your car might be leaking oil after an oil change, and what you can do to address the problem.
Why Is Car Leaking Oil After Oil Change?
Oil leaks can occur for a variety of reasons, and it’s essential to identify the root cause to prevent further damage to your car’s engine. Here are some common reasons why your car might be leaking oil after an oil change:
1. Improper Oil Change Procedure
One of the most common reasons for oil leaks is an improper oil change procedure. If the mechanic or DIYer doesn’t properly drain the old oil, it can cause the new oil to leak out. This is often due to the old oil not being fully drained, or the new oil being poured in too quickly, causing it to overflow and leak out.
Signs of an improper oil change procedure:
- Oil leaking from the oil drain plug or filter
- New oil not being properly sealed
- Old oil not being fully drained
2. Faulty Oil Drain Plug
The oil drain plug is a crucial component that seals the oil drain hole. If it’s faulty or not tightened properly, it can cause oil to leak out. Over time, the plug can become worn out or damaged, leading to oil leaks.
Signs of a faulty oil drain plug:
- Oil leaking from the oil drain plug
- Oil dripping from the underside of the car
- Oil stains on the ground or garage floor
3. Worn-Out or Damaged Oil Filter
The oil filter plays a crucial role in filtering out impurities and debris from the oil. If it’s worn out or damaged, it can cause oil to leak out. A clogged oil filter can also restrict oil flow, leading to oil leaks.

4. Oil Leak from the Engine Block or Cylinder Head
Oil leaks can also occur from the engine block or cylinder head due to worn-out or damaged engine components. This can be caused by engine wear and tear, overheating, or excessive oil pressure.
Signs of an oil leak from the engine block or cylinder head:
- Oil leaking from the engine block or cylinder head
- Oil dripping from the engine compartment
- Oil stains on the ground or garage floor
5. Faulty Oil Pressure Sensor
The oil pressure sensor monitors the oil pressure in the engine and sends a signal to the dashboard display. If it’s faulty, it can cause oil leaks by sending incorrect signals to the engine management system.
Signs of a faulty oil pressure sensor:
- Oil leaking from the oil pressure sensor
- Oil pressure warning light on the dashboard
- Engine warning light on the dashboard
