OEMTOOLS 24938 Pneumatic/Manual Fluid Extractor, 9.5L Oil Extractor Pump

This worked great to extract the heavy gear oil out of my front and rear differentials. I used with a compressor and made it very easy. Seems very well made, no leakage at all, great value!

Works great for oil changes. Just used on a Infiniti QX 70 and when I removed the oil plug, no oil came out. Only used the manual hand pump this time too. Great for vehicles with the filter on top. On these vehicles you won’t have to crawl under the vehicle to remove the drain plug.

Works great. The hose collar is unconventional. It is used to push the hose off rather than retain the hose. I thought at first the collar didn’t fit…after I read the BIG YELLOW STICKER it made more sense…

Really feels like a quality product. I have a Promaster 3500 which has a top accessible filter housing and with this makes oil change a breeze. I have only used it once and will probably not use it on our Toyota since filter is only accessible under the vehicle. Directions are terrible. And yt vids are not great for set up but it is intuitive. All connections are friction based and held in by the suction generated. There are 2 end hoses included, I only used the dip stick hose and I knew the depth to the oil pan from other videos about the van. You attach the thin dip stick hose (or the other for other fluids) to the wire reinforced tube (made in Japan, not China) which connects to the top of the evacuator. This was the only tricky part since there is a screw-on collar there. That stays screwed on when you evacuate the oil. The cap is later unscrewed/removed so you can empty the oil without making a mess. You turn the Venturi valve 90 degrees if you are hand pumping (you can also use a compressor but the manual mode worked so well I wouldn't bother). I heated the engine oil to 150 F (temp via OBD scan gauge) Got everything ready to go and pumped about 8 times and out came the oil. Pumped a few more times during process but only a few. Emptied the 6 quarts (right to the top of 1.5 gallon capacity) in under 10 minutes; didn't time it and may have been as few as 6-7. Easy to empty back into the 5 quart and 1 quart oil containers (with a funnel and with stabilized containers) at the end but did subsequently leave it inverted to let the last cooled down oil drip out later, as I did with the hoses. Hoses are the hardest to deal with emptying. Very little mess and the only oil I had to really clean were drips from the hoses and, ironically, a little spillage adding the new oil. Still used some cardboard and was glad due to the few drips.

Seems well made. Was going to use it to extract trans fluid from my Silverado HD2500 and the tube is not long enough. They should provide a longer tube for the price of the extractor. Tried with a gallon of windshield washer fluid both pump and air; both worked fine.

I purchased this based on the recommendations of a car forum, and I'm glad I took the advice. As I get older, it gets harder and monotonous to keep crawling underneath my car to change the oil. Additionally, the stakes are higher as now I support a family so if I accidentally pull the car down on top of myself, the loss will be felt wide-spread so I need to be more responsible not just for myself but others as well. I bridged this responsibility by taking my car to the local Firestone and eating the 75 dollar oil change fee, but it keeps me safe and keeps my car maintained. The issue though is that I own multiple cars, and they are not Maserati's that necessitate dealership expertise to change oil. There needed to be a happy medium and this is it. The process of using this device is that you hook it up to a large capacity air compressor and you stick the tube into the dipstick tube of the car that you are changing the oil on. You turn the lever on top to on and the air from the air compressor creates a vacuum that immediately starts sucking oil out of the engine. Once the oil canister is full, you can then refill the engine using the proper oil grade and quantity of oil and you are good to go. Just a note, this device will not work by itself. It needs a large capacity air compressor to work larger than most common households will have. (Think 220V, not 110V). If you already work with pneumatic tools and your garage is a shop environment already, you will have this compressor already more than likely. If this is your first timid step into the deep end of the car maintenance world, you will need to make the investment into the compressor to get the full value out of this. Most of your modern front wheel drives cars are going to have top-loading oil filters that allow you to change the filter from the top of the engine bay, so with this device you can do a complete oil change and not have to get underneath the car.

I have use it for oil, transmission fluid, power steering. On all my vehicles, yard equipment and generators. Works so easy that I have not use the air system. CAUTION: there is a plug in the back that MUST be in place to cause a draw, it\f is out or missing will not work. The way it is attached to the pump falls off easy.

I have what I thought was a very simple question concerning the OEMTOOLS 24937 oil extractor pump that I purchased in Aug of 2025 - What size gas cap does this product take so I can safely transport used oil to recycling? Now, it shouldn't be complicated to get an answer to this right? We've emailed them, no response. So, I tried to contact them through Amazon. I opted for the "Get a call" option for this product. I supplied my number and was called back by Amazon who asked me to select 1 if I was calling about support related to my order. I entered 1 and was informed by the Amazon recording that a manufacturers agent would be with me shortly. The phone rang twice and a recording came on saying "Welcome to America's Hottest Hotline". I then was given the option to select 1 or 2 to speak to hot ladies or hot men. I hung up and went back to "Get a call" and yep, the sex line operator repeated her pitch. WTH? Amazon,check into this, I recorded the 2nd time so ask me and I'll send it to you. OEMTOOLS, check in to this! Customers should be able to ask questions about a purchased product without this nonsense. Till then I strongly do NOT recommend this product.

Works Great!..... vacuumed 8.8 Liters of engine oil from my Mercedes ML550 in about 5 minutes, with the air compressor hose attached. No muss, no fuss. Best tool ever. Highly recommend. God Bless.

Es un buen producto. Lo recomiendo incluso para uso comercial como talleres de cambios de aceite. Mucho mejor que el ean23 de mikels que cuesta el doble. Lo único que pediría sería un instructivo en español con una reseña más amplia sobre el mantenimiento y la limpieza, ya que esto en el instructivo es casi nulo.

Es una ayuda muy grande y sobre todo práctica para sacar el aceite excelente herramienta muy buena compra vale la pena comprarla

Great product, its payed its self off already. As a automotive Technician we use these kind of tools all day long. It's easy to use and the product is made of good quality material. Its payed its self off already by performing multiple brake fluid services. I would strongly recommend it to any auto tech, looking to buy a new brake bleeder tool.

work perfectly
