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.
