Engine Oil Change with Fluid Extractor | DIY
In this guide, you will find step-by-step instructions (with pictures and video clips) that demonstrate how to change engine oil using an oil extraction pump.
This method is a quick, easy, and safer way to change engine oil. Often this is referred to as the top-down or topside oil change method.
Benefits of using an oil extraction pump
- Fewer tools required to change the oil
- An easier and safer method to change the oil
- You don't have to struggle with removing the drain plug. No need to replace the drain bolt washer either.
- No chance of an oil leak due to improper torque of the drain plug.
The only drawback of changing the engine oil with an extraction pump is that a minimal amount of old oil may remain in the pan.
It is insignificant since typically less than 5% of old oil remains. If you do regular oil changes, then an oil extractor is perfectly an acceptable way to change the oil.
In a neglected engine, debris and sludge sit at the bottom of the oil pan and may not be picked up by the oil extractor.
What you will need
- Oil Fluid Extractor Pump
There are two main designs to consider.
- Oil Vacuum Extractor
These oil extractors come with a container and a manual pump that you will have to pump to get the oil out. The oil vacuum extractors have been around for a long time. Not only do they require manual labor, but they also are large and require space to store them.

- Electric Oil Extractor
An electrical oil extractor is a lot easier to use. Connect it to a 12-volt battery source such as your car battery and let it do its job. You will need a container to collect the old oil, but that's not an issue. The other advantage of using an electrical oil extractor is that they are very easy to store and put away.

If your oil filter has to be accessed from the bottom of the engine, you will need to use ramps to raise the car and get to the filter. If your oil filter is on top of the engine, you don't need ramps.
- Oil filter removal tool
Regardless of your oil filter is on top of the engine or the bottom, you will need an oil removal tool. There are many oil filter tools on the market, such as a three-prong oil tool, strap oil filter tool, and chain oil filter tool. Ideally, our favorite tool that works better than any of the ones we mentioned is oil filter pliers, as they work on almost any oil filter.
Before you get started
Check if your car has an oil dipstick. Some cars do not have an oil dipstick and tube.
This was common among European cars between 2005 and 2010, especially with BMW and Mercedes. Newer car models typically have a dipstick, even the European ones. Just double check before you get started.
Follow these steps to change the oil using a vacuum extraction pump or electrical pump.
Get the engine oil warm, Turn off the engine and let it cool down for at least 15 min. If the engine is cold, start it up and run it for a couple of minutes. You want the oil to be warm but not hot. Open the hood and remove the oil dipstick.
Insert the tube into the oil dipstick.
Push the tube until it stops. Typically it should go into the dipstick about two to three feet. Note that some extraction pumps have two piece tube.
Ensure that the two tubes are tight together. Otherwise, one of the tubes can fall out and get stuck in the oil dipstick.
Connect the oil extraction pump. If you are using a 12V Motor Oil Extractor, insert the other side of the tube (discharge side) into an empty container. Ideally, a clear container or one that you can measure the amount of oil that you are extracting.
Connect the extraction pump to your car battery.
Positive: Red clamp on (+) battery post (note red battery cable).
Negative: Black clamp on (-) battery post (note black battery cable).
- Extract oil from the engine Turn on the extraction pump.
- If you are using a vacuum extraction pump, there is no need to connect it to the battery because you can't. Instead, start pumping the oil and be ready to get a good workout.
- Suck out all of the engine oil
- Let the oil extractor pump run for about 10 to 20 minutes. You will know when it is finished extracting the oil, as you will see air bubbles on your oil container. If you pay close attention, you will notice that the sound of the electrical oil extractor will change when it is finished extracting the oil as at this point, it will run dry.
- When you think all the oil is extracted, move the tube into the dipstick by pushing it down or twisting it slightly. This will ensure you are sucking all the oil at the bottom of the oil pan/sump.
- Remove the oil tube from the engine. Make sure to have a rag ready as a small amount of oil will drip out of the tube.
- Replace engine oil filter
- If your oil filter is on top of the engine, consider yourself lucky. Replace the oil filter, which in most cases is cartridge oil filter type usually found on BMW and Mercedes-Benz.
- On Japanese and American cars, you may need to get under the car to access the engine oil filter. Roll the car up on ramps. Make sure to set the parking brake and block the rear tires.
- Add engine oil. Check your owner's manual for the amount of engine oil you need to add. Add the recommended quantity minus half a quart. If your car requires 4.5 quarts, add only four as a starting point. Let the oil make its way to the oil pan and check the engine oil.
- Check the oil level and add more oil if necessary to bring the level between the Min and Max mark.
- Don't force the suction tube in the dipstick if it is too large. Otherwise, you risk getting the tube stuck in the dipstick.
- Make sure the tube is pushed in all the way, and it is at the lowest point of the pan.
- On some car engines that have the oil filter installed on top. It is possible to remove the oil filter and use this channel to insert the tube and extract oil.
- Note that by changing the oil yourself, you may void your warranty. Unfortunately, some car manufacturers require that you pay a technician to change your oil.
Yes, there may be a small amount of oil left in the oil pan, but the same is usually true when you drain via drain bolt. In many cases, the bolt isn't always at the lowest point of the oil pan. If you have a well-maintained vehicle, there is no reason to worry about using the oil extraction method. Make sure to change the oil filter as well.
- Make sure the oil extractor has a large capacity to hold all your oil.
- Consider an electrical oil extractor.
- If you are buying a vacuum oil extractor, look for one that allows you to easily discharge the old oil.
Two of the most used oil extractor are the vacuum type and electric oil extractors. Both these methods are great for alternatives if you are looking to use them for DIY oil changes.

If you change the oil regularly, using an oil extraction pump is acceptable. Note that the benefit of removing the drain plug and draining the oil is that you get out almost all of the old oil. When using an oil extraction pump, a little bit of old oil will remain. If there are any small amounts of metal debris or particular matter in the old oil, it shouldn't be a problem as the oil filter will trap them. Make sure to replace the oil filter even if you extract the oil.
If you have an engine that thus engines sludge, it is better to drain the oil than extract it. Don't neglect your car. Change your oil at the recommended intervals, and you shouldn't have this problem.
Using an oil extractor is a great way to change the engine oil as long as your car has a dipstick. If your oil filter is mounted on top of the engine and you don't want to invest in a lot of tools to do basic car maintenance such as an oil change, this method will save you money, time, and headaches.
Did you know that in some cases, such as (Smart cars) the only way to change the oil is using the oil extraction method?
Changing the motor oil with an oil extraction pump is the perfect method if you are just starting with a DIY auto repair or are tired of making a mess every time you change the oil.
Make sure to recycle your old oil. All auto parts stores that sell oil, including AutoZone, Advance Auto Parts, PepBoy even Walmart, collect old oil free of charge.
