When it comes to vehicle maintenance, every component plays a crucial role in ensuring the smooth and efficient operation of your car. One often-overlooked but vital part is the oil drain plug.

In this blog post, we’ll explore what an oil drain plug is, its significance in vehicle maintenance, and its common sizes.

What Size Is Oil Drain Plug?

The oil drain plug is a small, threaded bolt typically located on the bottom of your vehicle’s oil pan. Its primary function is to provide a convenient access point for draining the old engine oil during an oil change. Once the old oil has been drained, the plug is reinserted, sealing the oil pan to prevent leaks, and fresh motor oil is added.

Significance Of The Oil Drain Plug

The oil drain plug plays a pivotal role in vehicle maintenance:

  1. Oil Changes: During regular oil changes, the drain plug is removed to drain the used oil. This ensures that your engine is supplied with fresh oil to maintain optimal lubrication and cooling.
  2. Preventing Contamination: By removing the old oil, contaminants and impurities that accumulate in the oil over time are also removed, ensuring that the engine runs efficiently.
  3. Sealing the Oil Pan: The oil drain plug serves as a crucial component to seal the oil pan after an oil change, preventing oil leaks and maintaining the integrity of the oil system.

Common Oil Drain Plug Sizes

Oil drain plugs come in various sizes and configurations, depending on the make and model of your vehicle. The most common sizes are:

  1. 1/2 Inch: Many vehicles, especially older models, use 1/2-inch drain plugs. These typically have 20 threads per inch (TPI).
  2. 12mm: A 12mm drain plug is common on many modern vehicles, and it’s typically used with a 1.75mm pitch.
  3. 14mm: Another common size, the 14mm drain plug, is often found on larger vehicles, trucks, and SUVs. It typically has a 1.5mm pitch.
  4. M12x1.25: This is a metric size often used in vehicles with European or Japanese specifications.
  5. M14x1.5: Another metric size, M14x1.5 is common in many Asian and domestic vehicles.

It’s essential to know the correct size and thread pitch of your vehicle’s oil drain plug to ensure a proper fit during an oil change.

Regular Maintenance Matters

Proper maintenance, including routine oil changes and checking the condition of your oil drain plug, is critical for the longevity and performance of your vehicle’s engine. Neglecting to change the oil and maintain the oil drain plug can lead to engine damage, reduced fuel efficiency, and costly repairs.


The oil drain plug may be a small and often unnoticed component of your vehicle, but its role in engine maintenance is indispensable. Understanding its size and ensuring it’s properly maintained is essential for maintaining your engine’s health and the overall longevity of your vehicle. Regular oil changes and proper care of the oil drain plug are integral parts of responsible vehicle ownership.
