Mityvac MV7300 Pneumatic 2.3 Gallon Venturi Vacuum Pump Fluid Evacuator, Uses Compressed Air, Chemical-Resistant Polyethylene, Air Shut-Off Valve, Overflow Prevention, Quick-Drain Spout, Large Base

I have 3 cars, a jeep, a Volvo and a VW Passat so sometimes it seems like I am running my own little oil change shop. Anything that makes things easier is much appreciated. The Volvo and the VW have belly pans that have to be removed to do a regular drain plug oil change which is a real pain but both also have oil filters accessible from up top. So the MityVac makes oil changes tons easier on these cars. No need to get on the ground at all. If you have a car that fit this description one of the MityVac fluid extractors is must. It takes oil changes and moves them from being a Saturday morning project to something you can just whip off while waiting for dinner to be ready. No ramps, no messing with the belly pan, no changing into something you don't mind laying on the garage floor in, no laying in slush in January, etc. (On the other hand, the Jeep filter change requires getting on the ground anyway and there is no belly pan to remove so while the MityVac does work on the Jeep, I'm going to stick with the Fumoto valve technique there since I'm under the car anyway and the valve plus some tubing puts the oil directly into my disposal container a/k/a empty milk jug. If your car requires getting on your back anyway to change the filter I suggest looking into the Fumoto valve). It takes about 15 minutes to suck 6 qts of oil out. That's probably about the same as it would take to drain but it does result in time savings since you can get started in less than a minute then go gather up what you need to do the filter change and start on the preliminaries while it sucks away. Really, it is the convenience rather than outright time savings that makes this thing worthwhile. Added bonus - my lawn mower and power washer (both of which lack drain plugs) are now going to get more regular oil changes and I'm looking forward to using it to do a power steering fluid change, my next differential fluid change on the jeep and to bleed my brakes (it comes with a bleeder attachment). Well worth the price. At least on my cars, it pulls out as much oil as draining does (note, if you start off a quart or 2 low, it will not magically manufacture oil for you so the test is not how much it sucks out but how much you have to put back in). I have a 26 gallon compressor and it can do a whole change only cycling on once near the end. I use 100 psi. It was actually quite a bit quieter than I thought it would be. There is a plug in the top that pulls out to reveal a nice pour hole with a little spout for pouring the oil into a disposal container. The tubing is just long enough to do my cars which means its not long enough to do a truck without putting the MityVac up on something. But, the tubing is just generic poly tubing and there are no fittings so it should be easy to make longer tubing. I haven't tried it but there is a picture on the box of 2 of the included pieces of tubing connected together and it does look like the largest size might fit into the plug connectors on the ends of the other two pieces. (It is true the instructions are worthless. Don't even bother reading them).

I used this for the first time today. I had to get a air line adapter and then hooked it up to do an oil change. I had the car our for 5 miles, came back and started the job. First the air drag on this item you really need a large air compressor. I don't recall seeing any cfm ratings but I have a 130# 30gal tank which is probably larger than most people. If I had a pancake or cheap compressor I think this item would not do you justice. My compressor was cycling on about every 3 minutes with this thing running with a 100 lb regulator and pressing back up to 100. The air flow to get this drag is considerable so if you have a low CFM rated compressor you will not have good results. I also noted the tube lengths. I have read about he tubes connecting together but I opted to just go up to the big box hardware and you can get 25ft of 1/4" polyethylene tube for under 3 bucks. No sense in adding connections to the line. The connecting of tubes also allows for air leaks so when you consider the best vacuum, the less connections the better. The next thing is the drain plug. It was hard to remove when new. I got it open and used some silicon lube spray to get the o-ring lubed up. Again for good vacuum this o-ring needs to seal the top of the container to get that suction. Now I hooked up my air line, running on a regulator at 100#. It was pulling that oil out of the drain plan with good pull. The weather here was 45-50F and it took me about 45 minutes to pull 4 qts of oil. No mess, very simple to do. I had the drain cap off to prevent vacuum in the engine. I would imagine in the summer weather I'd get a better drain rate but it did the job. Now just have to take the oil to recycle and I'm good to go. Overall I think the product is good and can help with a lot of maintenance on a car or small engine. The length of the tube is really the low point in the design especially when the big box hardware has them for around 3 bucks. I have a few more cars to use it on but it was nice while I was out today, I was able to drain and refill the power steering reservoir in about 2 minutes.... I'm guessing the oil in there was from 10+ years ago. those who had bad luck I would consider the seals of the container, the o-ring at the drain top, the hoses and fittings and do you have the proper air compressor to really run this. The directions are not very telling so it's a learn as you go. I'm guessing that in 3-4 oil changes I'll be ahead having bought this.

This is one of my favorite products. I can change the oil from the dipstickon top whether it's my super duty f250 or my Mercedes-Benz. I never have to go down below and risk getting crushed by the MB

I sat on this Mityvac for 3 month before using it for the first time today as both my Acura & Chevy Silverado 3500 are due for engine, A/T fluid change. First of all I want say "Thank You" to those provided product review on this Mityvac-7300, your feedback lead me to a purchase that I know will save me money & headaches many times over. I had to spend $370 for dealer to replace the oil pan on my Acura TL last year because the dealer mechanic stripped the thread. Worst of all they claimed these happen quite often because the pan is made out of aluminum to save weight & provides better heat dissipation etc. etc. etc... 6 month later my Chevy truck developed an oil leak from drain plug; needless to say it's caused by stripped threads. I took a leap of faith & had the drain plug bolt "welded" to the pan & stopped the leak for good so I now rely on this Mityvac exlusively for oil changes. Design: Comes w/ 3 tubes which are slightly "short" to be fully functional on their own, but the male-end can be inserted to the female-end, so you can combine all 3 tubes together & form a 15 feet suction tube. So the alleged disfunctional short tubing issue is a very easy fix. I do wish that it came with a compressor hose adatpor where you can just plug in the hose straight into the bottom, but that's a minor inconvenience, just go buy a $12 compressor hose kit from Walmart & problem solved. Operation: Instruction manual is worthless but thanks to a straight forward design, it's a no brainer to figure things out by looking at the picture on the box. Took me less than 3 min to pump out 3 qts of AT fluid & 6 min to pump out 5 qts of engine oil out of my Acura. The Silverado took about 8 min for 7 qts of engine oil & 10 min for over 10 qts of A/T fluid because I combined all 3 tubes together & consequently created more resistance on the suction. After all fluids are extracted, I simply reach under the hood to unscrew oil filters & screw on a new one. Wow!! No Mess.. Tips: (1) Finding the bottom can be slightly tricky as you don't know whether the end of tube touched bottom or not, even if you feel resistance it could mean the tube is just pressing against something. Best practice is "line-up" the tube next to the "dip stick", mark the tube with a Sharpie so the marking indicates the exact length of your dip stick; this way you'll know exactly when the tube hits the bottom which will give you maximum fluid extraction. (2) Work when the car is warm & preferrably hot. Fluid flows much better & you'll get a much better extraction. Monetary benefit: So far I have saved myself 2 trips to dealers for the following: (1) Acura engine oil/filter change & A/T fluid change. (2) Chevy Silverado engine/filter change + A/T fluid change. My material cost for 2 filters, 12 qts of synthetic oil, 10 qts of Dexron III A/T fluid amounts to about $150. Had I gone to the dealers, my bills would have gone over $400. Not to mention risking someone over tightening the drainage bolt & ruining another oil pan.. I know there are some other fringe benefits of going to a dealer for routine maintenance such as car washes & tire rotations etc. I do my tire rotation at Costco & car wash at home with my pressure washer (quite fun, actually). Conclusion: You be the judge, if you are just borderline mechanically inclined like myself & thought about saving some money on maintenance, you definately should give this Mityvac a try. This has been the best investment I've made on automotive needs so far and I plan on using it for my lawn mower, motorcycle etc.

I used this for the first time to replace 10W-40 motor oil in 8.1 GI-J boat motor. Worked well but took some time when using the smallest of the 3 straws provided to remove ~6.25 liters of warm motor oil. I hooked up the air and started building vacuum prior to opening suction hose. While building vacuum I pushed the suction hose down the dip stick tube to the bottom. The Suction hose ball valve not a built to close tolerances because with the ball valve closed it began sucking motor oil as soon as I pushed the smallest diameter hose into the rubber coupler. Rubber couplers are not tight fitting either but no oil leaked out while vacuuming. Seems efficiency would be greatly improved with better sealing components on the suction end, but really these aren’t huge issues. The semi-transparent container has volume markings on it and you can easily see level (as long as the fluid is dark). Easy to empty used oil into whatever storage container you may have with the spout on top. The unit appears to sturdy and hopefully will used in my garage for many years to come. Overall the tool worked well and I would recommend it. Any improvement aside from fixing suction side would be an addition of hose storage on the canister to make it easier keeping everything together.

This pump works great. I've used it on both cars and machinery, including drawing nearly 10 gallons of hydraulic fluid on one job (Emptying between pulls, it holds about 2 gallons which is enough to empty my cars and boat in 1 pull). I have a smaller, 2.8 CFM Bostitch compressor. It runs constantly while extracting but the rate of extraction is fine. Maybe 5 minutes for 2 gallons. For oil changes I no longer need to jack or use ramps, no laying on the ground, no oil running down my arm or dropped drain plug searches in spent oil, and no more crush washers! I have a manual pump I used on my boat, which is a bear to pump and leaks constantly. I'm donating it and good riddance. If there is any downside, it is the size, as it takes more space on the shelf. But I feel relief when I see it there! It also does not come with a quick disconnect, which is disappointing given the price point, so I had to pick one up to attach my compressor (Air Hose Fittings and Air Coupler Plug, Air Compressor Quick-Connect MNPT Male Plug). This unit comes with suction hoses of various sizes, it's clean in operation and has a pour spout for transferring spent oil. You need it!

My OEM Tools vacuum extractor failed after a few years. I'd rather not have one with the mechanical hand pump. This one is much simpler with the venturi vacuum. The included equipment all seem good and reliable. Mityvac is a great brand so I trust this will last. Just had to add the nipple for my compressor quick-disconnect fitting.

We have a range rover and this has made oil changes a breeze! I have found tons of other uses around the shop for it, including coolant and washer fluid when repairing vehicles. I would probably go back in time and purchase the mity-vac with a hand pump so i could also use it when I dont have access to an air compressor, but thats my own fault for not thinking ahead. This is a must for a serious DIY automotive person or a professional like myself who uses it at work often. You can save yourself a ton of clean up and wasted oil dry by sucking the fluid out of the car instead of draining it in a drain pan (and spilling it around the drain pan)

Used this tool a few times already to service a power transfer unit and rear differential. My vehicle does not have drain plugs for these gear boxes (only fill plugs) and the manufacturer claims the fluid inside is filled for life. There are many documented cases of mechanical failure due to lack of maintenance with this particular set up so i decided to purchase a fluid evacuator to facilitate some sort of maintenance. This one was not the cheapest one available but i figure i have already covered the cost with the number of jobs i have done with it. I do have the luxury of being able to hook up to shop air so i have been quite satisfied with its performance.

Works awesome. Definitely should have had this years ago.

Has good suction

Product didn’t work out of the box, have used these products a lot as an auto tech guessing I got a dud. Seller offered to take back not sure at this point if I will get refund or exchange. Would give the seller a 5 start for prompt communication but the product as it didn’t work would hope it’s just a fluke and not all of them
