  • Oil Extraction method: This is a process of oil extraction where you pull oil out straight from the crankcase. Here, one inserts a long and thin tube into the dipstick. The handles help it to create a vacuum so that the oil gets sucked out and taken somewhere else for disposal.
  • The Draining method: Here, the process is simple. You will discover that every engine has a plug attached to it. Once you remove this plug, the oil will flow out to the container which you placed beneath the tank.

Oil extractor vs. Drain: Which Method to Pick?

The many times you change the engine oil, the longer the lifespan of your engine. As a result, you need an efficient method of exchanging oil from the engine so that you don't spend more money on buying another engine. 

There are different oil contaminants from various sources. An excellent example of such is combustion gases from gasoline. These gases usually have negative impacts on the engine cycle. 

Luckily, two methods are available for removing old oil from the engine and replacing it with new oil.

1. Changing Oil by Using the Oil Extraction Method

When it comes to changing the engine oil, things have never been more natural. It's always a messy and lengthy process that needs careful handling. The oil extraction method tries to make things more comfortable because it comes with its large container, a handle, and a long pump. 

Overall, when used at once, it creates a vacuum, which in turn sucks all the oil out from the engine. 

It is the cleanest method to use since it leaves little or no mess behind after the sucking process. In most cases, they have a spout, which even makes it easier for the oil to flow out easily.

Additionally, you don't need to raise your car to extract the oil, which is usually a costly process. Its major drawback is that about 6% of the oil will remain inside the tank. 

Pros

  • It's a clean process of oil extraction
  • There is no need for raising your car
  • It doesn't damage your draining plug
  • It's a straightforward method to use.
  • Your car can stay flat on the ground.

Cons

  • Some of the oil will remain in the engine
  • It is time-consuming.
  • It isn't tranquil.
  • It needs a lot of clean and compressed air supply.

2.  Changing the Oil Using the Draining Method

In most cases, mechanics rely heavily on this method, and it has been used for centuries now. This method saves your energy and time as it is the fastest method of draining oil from the engine. It only takes around 5 minutes, and the whole process will be through. 

Plus, you'll change every bit of oil from the engine, including the sludge. This sludge usually accumulates at the bottom of the tank.

Additionally, this method saves energy. Your central role here is to remove the plug and allow the oil to flow out by the gravitational force. Meanwhile, you can be doing something else while the oil gets drained. 

On the other hand, this process can be equally messy if the drain is slightly misplaced. The oil can miss its target and spill everywhere. It can be a frustrating process since oil proves to be the hardest stuff to clean.

Also, you will need to raise your car so that this process can take place, which can be costly.

Pros

  • It saves a lot of time
  • All the oil gets removed from the engine
  • You can perform other duties while the process is ongoing.
  • It's a typical method of changing oil.

Cons

  • You need to raise your car for the process to take place.
  • In the case of oil spillage, it isn't effortless to clean it.

Which method should you choose?

Both of these methods are good to use, depending on your choice and preference. If you’re a person who loves faster ways that are messy, then it is good to go for the draining method.

Still, if you want a cleaner way of taking oil from the engine and you can do it at your own time, then choose the oil extraction method.

In most cases, people will go for a cleaner method. The two above will serve your purpose. Fear not, take action and save your engine's lifespan.
