Many drivers outsource the relatively simple job of changing their oil because it is a messy and time-consuming chore. Investing in an oil extractor is an effective way to make changing a vehicle's oil a cleaner, simpler process. An oil extractor vacuums the oil from the oil pan and holds it in a designated container until the owner is ready to dispose of it. Understanding the various types of oil extractors and how they work helps car owners learn how to buy and use this handy device.
How oil extractors work
Oil extractors are not just for cars and trucks. They are also suitable for use with lawn mowers, tractors, and boats. The user inserts the oil extractor's evacuation wand into the chamber that houses the oil dipstick. If using a manual oil extractor, the user operates a hand vacuum pump to remove all the oil from the tank. Pneumatic models connect to an air source that powers the pump, while electric models connect to a battery. The oil extractor wand connects to a tube that leads to a chamber that safely contains the engine oil.
Types of oil extractors
When choosing an oil extractor, buyers have manual, pneumatic, and electric options. Many pneumatic and electric extractors come with a manual mode as a backup in case the owner does not have access to a power source. There are also universal or generic oil extractors that work with a variety of machines as well as model-specific extractors that have extraction wands of a specific diameter and length to ensure compatibility with a certain vehicle.
Manual oil extractor
The manual oil extractor is the cheapest type, but it is also the most labour intensive. It is best suited for small oil tanks in household machines or for infrequent use.
Pneumatic oil extractor
A pneumatic oil extractor attaches to an air compressor, which sucks all the oil from the tank without user effort. This model requires a source of compressed air and works well for individuals who do large-scale or frequent oil changes on vehicles or machines.
Electric oil extractor
Battery powered oil extractors can conveniently attach to the vehicle's battery as the power source. This option is popular for changing the oil on boats and other types of watercraft that may not provide easy access to an electrical outlet.
Oil extractor features
Aside from the type of power source, buyers should also consider what features they want in an oil extractor. Shape, size, and reservoir capacity are important as are safety and convenience features.
Size and Portability
For small projects, such as changing the oil in a lawn mower or pressure washer, a small, portable extractor with a handle is a logical choice. When removing large quantities of oil from a large vessel or servicing multiple vehicles, buyers should opt for a large extractor with wheels.
Oil extractors come with reservoir capacities that measure anywhere from approximately 1.5 litres to 95 litres. Smaller sizes are ideal for the occasional home user, while larger tanks are best for daily or commercial usage.
Safety and Convenience
Some models offer an automatic shut-off valve to prevent the reservoir from overfilling. Others come with the capability to pump the old oil from the holding container to the appropriate disposal or recycling area. Extractors with multiple evacuation tubes do an exceptionally speedy job of removing oil.
Using an oil extractor
Once the user removes the cap to the dipstick opening, he inserts the extractor's evacuation wand or wands. On some models, the evacuation wand attaches to a long tube, giving ample length to work. If there are multiple tubes, users should check every one to ensure they are securely attached.
When using a manual oil extractor, the buyer pumps it 10 to 20 times to form a vacuum. The vacuum pushes the oil from the vehicle or machine into the oil extractor's reservoir. When using air-powered or battery extractors, the user simply connects the machine to the power source, either an air compressor or battery, and then turns the machine on.
How to buy oil extractors on eBay
It is easy to find an oil extractor on eBay to add to your set of tools. Perform a keyword search for the extractor you want. For example, type "manual oil extractor" or a generic term like "oil extractor". Use the filters to reduce the number of results so that only the most compatible options display. If you want to bypass shipping fees on a large, heavy machine, look for local sellers who offer in-person pickup. With the right oil extractor, changing your oil is a tidier, less cumbersome experience.
