Can you use a fluid extractor to do an oil change?

Yes, you can use a fluid extractor to perform an oil change on your vehicle. A fluid extractor is a handy device that allows you to remove used oil through the dipstick tube without having to get under the car and drain the oil manually. While they require an initial investment, fluid extractors can make oil changes quicker and cleaner. They can also help extend the life of your engine by removing more of the old oil and residue.

How Do Fluid Extractors Work?

A fluid extractor works by creating suction to draw the used oil out through the dipstick tube. Here is the basic process:

1. Insert the extractor’s tube down the dipstick tube until it reaches the oil.
2. Connect the extractor’s hose to the unit.
3. Turn on the extractor to create suction.
4. As the suction builds, the used oil will be drawn up through the tube and into the extractor’s reservoir.
5. When the reservoir is full, turn off the unit and empty it before continuing.
6. Repeat as needed until the majority of oil has been removed from the engine.

Most extractors will remove around 4-6 quarts per cycle. For a typical 5 quart oil change, you’ll need to do this process 1-2 times to sufficiently drain the old oil. The key is to remove as much as you can through the tube until the oil runs dry.

Benefits of Using a Fluid Extractor

Here are some of the main benefits of using a fluid extractor for oil changes:

• Convenience: Don’t need to get under the car or deal with drain plugs. Just insert the tube and turn on the extractor.
• Cleanliness: Extractors remove oil without spilling or dripping. No need to worry about oil getting everywhere.
• Thoroughness: Extractors can remove more old oil and sludge than just draining from the sump.
• Speed: Oil changes often take half the time compared to manual draining.
• Versatility: Works on cars/trucks with no drain plug access or when vehicle is not level.

For those who change their own oil, a fluid extractor can make the process much simpler. No more crawling around and getting covered in grime. Just insert the tube and let the extractor do the work!

Potential Drawbacks

While fluid extractors provide convenience, there are some potential drawbacks to consider:

• More expensive initial cost than a manual oil change.
• May leave behind some residual oil depending on engine and extractor capability.
• Need to monitor and empty extractor as reservoir fills up.
• Will not remove oil filter, which still needs to be changed manually.
• Possibility of spilling oil when detaching full collection tank.

The key is finding a high quality extractor with sufficient suction power. Cheaper models may struggle to remove all the old oil. It’s also essential to visually inspect that the oil runs clear before finishing the job. Be prepared to get under the car if needed to open the drain plug and release any remaining oil.

How to Change Oil using a Fluid Extractor

Here is a step-by-step overview of changing your oil with an extractor:

1. Make sure extractor tank is empty and prepare work area. Have new filter, jack stands, and oil handy.
2. Raise front of vehicle and support it securely on jack stands.
3. Remove oil fill cap and insert extractor tube down dipstick tube until it hits bottom.
4. Attach extractor hose and turn unit on. Let it run until tank is full.
5. Turn extractor off. Carefully remove tank and empty oil into approved container.
6. Re-insert tube and repeat extraction process until oil runs dry. May take 2-4 cycles.
7. Once oil flow slows, lower vehicle, remove drain plug and drain any remaining oil into pan.
8. Replace drain plug, remove old filter and install new one. Refill engine with new oil.
9. Check dipstick and top off oil to full mark if needed. Replace fill cap.
10. Dispose of old filter and oil properly. You’re done!

The key steps are removing the initial bulk of oil with the extractor, then finishing off by manually draining the system. Always drain any residual oil before refilling. Take care when removing and emptying the extractor to avoid spills. Properly recycling the old oil is critical.

Types of Fluid Extractors

There are a few types of oil extractors available:

Manual Pump Extractors

• Manual hand pump is used to create suction
• Lower price but more physical effort
• Tank capacities typically 1-3 gallons
• Good for smaller oil changes

Electric Extractors

• Powerful electric motor provides suction
• More expensive but easier to use
• Larger tank capacities around 4-6+ gallons
• Better for bigger jobs and frequent use

Compressed Air Models

• Uses shop air hose attachment for suction
• Convenient if you already have air compressor
• Limitations on run time before needing to refill air
• Not quite as powerful as electric

For occasional use, a manual pump extractor may suffice. For frequent oil changes, an electric model with higher capacity will make the job easier. Pricing ranges from $60 for basic manual models up to $200+ for high-end electrical extractors.

Things to Keep in Mind

When using an extractor, keep these tips in mind:

• Insert tube gently to avoid scraping against dipstick tube
• Don’t tilt vehicle when extractor is running to avoid intake of air
• Make sure hose connections are secure
• Have an oil drain pan ready to catch any spills
• Wear oil resistant gloves when handling extractor
• Dispose of used oil properly – don’t just pour it on the ground

Overall, be sure to take all necessary precautions when changing your oil. Rushing the process or taking shortcuts can lead to mistakes. Have the right tools ready and give yourself plenty of time.

Conclusion

Using a fluid extractor is an efficient and cleaner way to perform an oil change. While they require more upfront investment, fluid extractors can save time and effort in the long run. Just be sure to select a quality extractor with sufficient suction power. Combining extraction with traditional draining helps ensure all oil is removed. With some practice, you can leverage fluid extractors to make your oil changes quicker and less messy.
