The 5 Best Fluid Evacuators [Ranked]

Fluid Evacuators

Fluid extractors are designed to evacuate all sorts of different fluids- that can include transmission fluids, engine oil, coolant, brake fluid and gear oil, etc. (Source).

Most fluid evacuators do not require any power in order to generate vacuum pressure that will evacuate and disperse these automotive liquids (Source).

They are frequently used by mobile car technicians, auto-shop service professionals, as well as DIY hobbyists. They are great for speeding up oil changes- performing them more neatly and cleanly (Source).

The Mityvac 7300 is our top pick- it is an air-operated fluid evacuator that has a 2.3 gallon/8.8 L capacity and features an automatic shut-off to prevent valve overfilling.

It's built from robust polyethylene so that it will not corrode or rust, and ships with a kit that includes a flexible hose that's 5 feet long, a universal brake-bleeding adapter and dipstick tubes.

Poor Instruction Manual?

The instruction manual is poor, however. Users say that for best results you should warm up the engine for 10-15 minutes before starting. 

Buyers also advised to keep an eye on the unit and don't rely on the automatic shut off to always work.

While the Mityvac has a lot of fans, it seems that there are some users that have not had positive experiences using this air-operated fluid evacuator.

One user who was happy with his purchase says that it makes brake flushes easier and less messy, and has also been great for power-steering flushes.

He also says that whenever he has overfilled a transmission in his auto mechanic shop, the Mityvac is able to suck out extra fluid in a clean manner, and it's also great for performing routine oil changes.

So, while there are some negative reviews from its buyers, in general most users are highly satisfied with this particular fluid evacuator- but be sure to do your own due diligence before purchasing and by all means return the device if it's not a fit for you.

That said, let's take a look at five of the best-selling pneumatic fluid evacuators on the market today.

Buying Guide

Fluid evacuators can make your job a lot easier if you are an auto mechanic and are routinely changing engine oil and other automotive liquids out of cars. One user who was working on his 2003 BMW 330i says that he has used the Mityvac 7201 many times to perform oil changes on his car. He says that this particular fluid and evacuator hold 9 quarts of oil, so he does have to stop the engine oil extraction process halfway, empty the reservoir, and then extract the remaining oil from his BMW.

One annoying thing that he notes is that the oil creates a dark film inside the vacuum pump itself so you can't actually see what level the oil is at as you are extracting it- so just to be safe he always empties it before he thinks it's full to ensure it doesn't overflow and create a mess in his garage. Another master mechanic with over 25 years experience who purchased the EWKtool vacuum fluid extractor uses it with transmission dipstick tubes- saying that he can evacuate fluid in under 50 seconds using his 140 PSI garage air machine.

He recommends that you should lubricate the vehicles of o-rings using silicone grease- and then also says that you should pay particular attention to fittings. There have been some issues evacuating synthetic oil- with one user saying that even with an air compressor he had to stop and start, allowing it to pull air out.

One savvy user writes that to maintain his 2016 Subaru that he was being overcharged at a local service station- so he decided, being an enterprising individual, to begin doing his own automotive fluid extraction in his garage. Since his oil filter was positioned on top of his engine, it was a lot easier than having to crawl beneath his car to do the fluid extraction.

Using an engine oil vacuum extractor

He advises to run the cars engine until the temperature has proceeded past the cold mark- not too far because you do not want to work with an engine that is too hot, just warm enough that the oil is warmed and easy to extract.

Then he used a dipstick to touch the bottom of the fluid extractor and began pumping until he began to experience resistance, removed the oil filter to facilitate airflow during the draining evacuation process, saying that it only took around 10 minutes to evacuate the fluid and then fill it back up with some Pennzoil Platinum.

Another solid tip is that he did not neglect cleanup- he rinsed the evacuator out, wiped down the reservoir, wrapping it in a towel so that it's clean and ready for his next use. Indeed, if used effectively with a little bit of practice, vehicular fluid extraction becomes much easier and cleaner than traditional methods.
