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!

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.

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.

The first three years worth of oil changes were included when we purchased my Wife's 2014 Volvo XC70. I performed the fourth oil change using Volvo recommended Castrol synthetic. Since this was her retirement car and we don't drive it much more than 4K miles a year now and the fact that we live 10 miles out of town (the vehicle is more than warmed up to operating temp every trip) I decided to extend the oil change interval to 2 years. For this last oil change I decided to actually read the owner's manual to see specifically what grade of motor oil to use. Turns out the Castrol I had used did not meet the ACEA A5/B5 specs called out in the manual so I decide to use Liqui Moly's Volvo specific formula. Therein lies the problem. I purchased an "oil change kit" from an on line (recommended) source which included the oil, a filter, new crush washer, new o-ring for the oil filler cap and o-ring for the filter housing. I received a large jug of Liqui Moly and three smaller containers. Prior to beginning the chore I rechecked the owner's manual to make sure I had understood. Yep, says right there "Oil volume 7.18 US quarts" I proceeded to empty the large jug and two smaller containers of the oil into the Volvo, opened the third small container and was looking at the gauge on the side of the container after pouring 8/10 of the container into the crankcase. Then it caught my eye. Written there, on the label, as plain as day it said 1L. Sure enough, Liqui Moly being a German brand measured their containers in Liters not quarts. DANG! Not only had I poured in what I thought was 3/4 of a quart too much turns out I had overfilled by an entire liter. Not wanting to try to remove a liter of oil via the drain plug I decide to order this fluid extractor. I had read a few reviews and found that someone said the oil dipstick tube was too short so I ordered a 1/4" tubing kit at the same time. Turns out the tube was long enough for the Volvo. I hadn't noticed when I ordered the extractor but there is a fitting that allows the use of an air compressor (and a corresponding ball valve for control) which eliminates the need of using the hand pump. My first use of this tool went well and made short work of extracting the oil. If there were any shortcomings that I experienced it would be that the instructions and illustrations were somewhat lacking especially when assembling the unit. Other than that I'm glad I purchased this extractor.

Works as described did a couple of fluid changes hand pump takes effort. Use the a good air compressor if you want good results🤪 . Great for DIYers. Not pro shop grade,but it works.

I used this extractor to do my first oil change ever. Incredibly simple and fast. I watched a few different videos online about them and decided to give it a go. I used the manual pump for this one, but wanted the pneumatic attachment incase I buy a small compressor. But it actually drained all the oil out pretty quickly. It took me a few minutes to get things going and it was stressful at first. I’m not sure what caused this, maybe the tip of the hose was bending, but at first I was getting no vacuum. I pushed as far as it would go into the engine tube, but it wouldn’t get proper suction. I kept pumping and nothing. Then I literally pulled it out about an inch and it started sucking the oil out rapidly. My car holds just under 5L, which it pulled out in about 5 minutes once I got the depth of the tube right. It started to lose suction at the very end so I gave it a few more pumps and moved the tube up and down in the engine to get the last few ounces out. Some people say extractors don’t get all the oil out, but this 6L was right under the 5 mark. So I can’t imagine much was left inside. It was incredibly easy. Didn’t get any on my clothes. And didn’t have to lift the car or remove anything other than the engine cover. Highly recommend.

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
