How Do You Suction Oil from a Car?

Many car drivers will often change the cars’ oil themselves. However, they usually face many disadvantages when lying under the car. Their hands are always stuck with oil that is not easy to wash off. Drain pumps are the surest way to remove old oil and all its contaminants before replacing it. When changing oil, the scavenging pump eliminates the hassle and mess of lifting the car, crawling under it, opening the oil plug, and collecting oil in the sump.

So, how do you suction oil from a car? Owning an oil extractor will be a method to suction oil from a car. 

Perform Top-Down Oil Changes

No matter which type of car you own, you can purchase an oil extractor to do your daily cleaning job. The oil extraction tool is straightforward and fast to use. You operate it the same way you would run a screwdriver that uses a handle with an interchangeable socket. The oil extractors are designed to simplify the process of getting the new oil and discharging the old oil. Oil extractors create a vacuum between the entire tank and the recovery tank. The fluid begins to flow to the recovery tank once the vacuum is achieved. The suction technique initiates the flow, and the vacuum created completes the process.

To perform a traditional oil change, you have to raise the car because the entire bottom of the vehicle is flat to maximize aerodynamics. It will help if you loosen the underbody to access the drain plugs and filters. If there is no lift available, ramps are the only options. Even then, the ramps have to be low profile so as not to spoil the fiberglass bodywork of the chin spoiler.

On the contrary, to change the oil in the top-down method, we open the lid of the mid-engine car and run the thin, flexible hose down through the dipstick hole. We attach the other end to the extractor, twitch the handle about 15 times, and the hot oil starts to flow. It’s best to put the rubber stopper into the oil separator, take the container to your local auto parts store and have them dump the old oil into the recycling bin.

Can You Get All The Oil Out?

When operated correctly, the extractor should be able to remove the majority of the old oil and sediment, leaving the new oil-free of pollution. It’s worth noting that most cars have a tiny amount of residual oil that can’t be drained or removed entirely during an oil change. Moreover, some drivers want to remove all the particles with the old oil, so the only solution is that if the car is warmed up as recommended before the oil change, all the particles will flow out with the oil. In addition, when water combines with oil, it will create sludge, a harmful gelling agent, but this has nothing to do with a successful oil change.

Criteria For Choosing An Oil Extractor

Oil extractor pumps come in various shapes and sizes to meet diverse demands and requirements. When purchasing one, you must make the best decision possible based on your circumstances. Pumping efficiency (how long it takes to extract a given volume of fluid), tank capacity (large enough to hold all the liquids you need to remove without having to be emptied mid-task), and pricing are all factors to consider when choosing the proper oil extractor pump. Moreover, today in the market, there are 3 oil extractor pumps: Manual oil extractor, Pneumatic oil extractor, and Electric oil extractor.

  • As the name implies, manual oil extractor pumps are operated with the hands. These usually have a handle that you may move up and down. Oil extractors are available in a variety of sizes and styles. They can be tiny, medium, or big, as well as light or heavy. The extractor may siphon oil on its own after only a few strokes before requiring another few pumps.
  • Pneumatic oil extractor requires pressurized air to function, making it an automatic tool. The stand gives the unit the strength to produce a vacuum, drawing oil from the engine’s oil sump. One disadvantage of pneumatic oil extractors is that they require an air compressor to operate. If you decide to get an air-powered oil extractor, it should be a combined model that is both pneumatic and manual. That means you can use them even if you don’t have access to an air compressor.
  • Electric oil extractors must be powered by electricity to function. The battery in your car is frequently the source. They’re simple to use; you press a button, and the extractor will suck oil into a container. Electric oil extractors also allow you to drain all the oil simultaneously because they don’t have a reservoir. The only significant disadvantage of these extractor types is their inability to be powered. Getting the proper wattage or amp rating for your application is vital when purchasing one.

To summarize, there are various types of oil extractor pumps available. The other important thing is that many models of car extractors are in the market with multiple features and prices. More significantly, it should be compatible with your vehicle’s oil capacity.

Advice For Using An Oil Extractor

Extracting engine oil rather than draining it is usually more convenient, but only if you know how to use an oil extractor properly. The article includes understanding what works and what doesn’t, as well as the guidelines for using the extractor. There are 6 steps for extracting oil, no matter the types of oil extractors.

  • Step 1: Warm up the oil

 Warming the oil also allows the sediments to combine and emerge with it. Begin by running the engine for 5 minutes and then letting it cool down. Cold oil is thicker and more difficult to extract with an oil extractor. Open the hood when the engine has cooled to begin the oil extraction process.

  • Step 2: Place the oil extractor tube inside

Remove the dipstick and open the oil-filled lid. Choose the extraction tube you want to use. Lower the extraction tube until it meets the bottom of the oil sump by inserting it into the dipstick tube. The depth is variable but generally between 2 and 3 feet.

  • Step 3: Link up the oil extractor

Insert the oil extractor unit into the extraction tube when it’s in position. Make sure you’re using the right connect approach for your extractor. Some extractors utilize an extension tube between the inlet and the extraction issue. Hookup the discharge tube at this stage if you’re using an electric oil extractor pump. Connect the compressed air supply for the pneumatic extractor.

  • Step 4: Set off the oil extractor

Pull the lever to its highest position and pump it roughly 30 times on a manual extractor. Keep repeating till all of the oil is gone. Turning the handle for the pneumatic oil extractor will allow pressurized air to enter and operate the pumping mechanism. Press the “ON/OFF” button should you use an electric oil extractor. Allow the extractor to absorb oil until the tube gurgles or bubbles develop inside.

  • Step 5: Finish the process

Keep pumping your manual extractor until you’ve done taking out the oil and release the pressure through the pressure release valve. To halt air flow in a pneumatic extractor, turn the handle in the opposite direction. To stop an electric extractor from running, push the “ON/OF” button and unhook the cords from the battery. Remove the inlet or extraction tube from the system and the dipstick. Wipe the oil away with a towel and fill a container with the extracted oil.

  • Step 6: Replenish the motor oil as well as the oil filter

Replace the oil in the engine according to the manufacturer’s instructions. Also, make use of the tools and procedures that have been recommended to change the oil filter. Finally, clean the oil extractor and keep it in a secure location.

Moreover, it would be best to look for key features when choosing an oil extractor. You’ll be assured to purchase a safe and correct oil extractor by following the below tips.

  • Consider safety, reservoir size, ease, and mobility when purchasing an extractor. This factor will guarantee that your vehicle is fitted correctly.
  • Because determining which extractor is best for your vehicle can be difficult, so look for independent customer evaluations and manufacturer requirements.
  • Warm oil is thinner and easier to pump. Warm up the oil by running your engine for a few minutes to make pumping more accessible and faster.
