EWK 10.5L Manual Oil Extractor Change Pump for Automotive Fluids Vacuum Evacuation

Before I ordered I read all the negative reviews, but decided to give to it a shot. I watched the video, and also a couple of YouTube videos about how to.When I received the box, I opened it, and at first impression it looked well made, good material, solid and sturdy.I was concerned because the negative review from the guy with the V8 engine saying it wasn't working with big engines....I have a Mercedes C63 AMG, big 6.3 V8 engine....I started the engine and let the oil reach 195F, shot engine off. I removed oil filter.I aligned the dip stick with the 0.21 diameter extension and made a mark on the tube as sign to were it supposed to dip, I inserted the wire in it, lowered the tube into the dip stick entrance and made sure it was reaching the bottom of the oil pan. and the mark I made was aligning with the top. The wire acted as driver true the bend entering the engine block.I removed the wire and connected the inserted tube to the main .39 diameter tube, them connected it to the tank and started pumping. I gave 4 pumps and the oil started to flow into the tank, gave 3 more pumps every minute. it took 4 minutes to suck out 9 quarts of oil, no leaks, no issues, it was effortless.Money well spent. I don't understand why the negative reviews, I think the issue wasn't the product.....

It looks well built and does the job as expected. It is easy to use. I have used it only twice (removed total of about 16 qt of oil). No issues either time.

Tried to suck out the oil on my V8 engine and the tube is not long enough to reach. Looked for longer attachments but non are available. Work fine if you got a little motor, but can’t hang with the big guys.

Appears to be a high-quality product. Well-constructed and simple but effective, right now I say it's a good buy.

I just recently bought a boat and needed to change the oil on my Mercury 150 outboard. I have it in a slip on the water at the marina. All the guys that I called wanted $650 to do it, citing $350 to haul it out for environmental purposes and $300 for the oil change. That’s never happening. I found this thing and MAN, IS IT AWESOME!!! Stick the tube down the dipstick and pump it a few times and just let it go. Removed every drop from my motor. And not one drop of oil dripped out. No mess, no environmental catastrophe, just a huge win. Thank you so much!!! Tip: if you’re using it to extract oil from an outboard, as soon as you can see it starts getting air, tilt it forward. Keep doing that little by little whenever you start seeing air bubbles until it’s all the way forward. It will suck everything out. Such a huge money saving win. I love this thing!!!!

It takes a little trial and error to get the wand in the right position to drain the whole tank, but generally easy to use. No crawling under the van!

I thought this would make my oil changes easier...WRONG!!! I couldn't get 1 drop of oil out with this thing on my 09 Ford Explorer. I out the hose down the dipstick tube and was able to get no suction. This after driving for about 5 mins. going and 5 mins coming back. Oil was up to temperature but the tubes hit the bottom of the dipstick tube and wouldn bend with the curve to the pan. The tubes are too narrow to make a seal so could not create suction. I had to get under neath and drain through the plug. This was a big waste of money, as I am beyond the return date...this thing is just an oil container to transport for recycling.

Great quality pump, I used it to change oil on my mercruiser 3.0 boat engine. Did an excellent job with it. I will be changing oil on my 2014 gl450 tomorrow so will see how it does. Pump seems to be very well made with attention to detail and high quality materials. Solid and robust design with excellent suction power.UPDATE on 2014 Gl450 with v8 engine. Tube is not long enough to reach bottom of engine. Because of that it left about 1 1/2 Qt of oil in. Had to drain the rest from bottom of car will have to get longer tube.
