Mity Wonderful
I am still wondering why I didn't buy one before now. Very handy tool, I used it to evacuate transmission fluid out of car (Toyota V6) and it worked great. Having the suction created on the down stroke makes it easy to use along with the extended foot step. I had to do some metric conversions and mark the side of container with lines, or you could just pour in known quantities of water and mark the sides. Knowing how much liquid you removed is needed for easy exchange. Three tubes included and so far long enough for my usage. The unit advises on a 175 degree rating so I usually wait about half an hour before removal so oil has time to cool off a little, this is also advised since you are really applying a plastic tube to hot metal parts under the hood. I can see many other uses for MityVac and recommend it.

Makes Oil Change so much easier
It drained out more oil from my car than pulling the drain plug underneath, I would definitely recommended to people doing their own oil change since it eliminates the hassle of getting underneath and made the oil change job a easy 30 min job. Built quality of this item is OK, not bad considering it's not that expansive, the price is pretty reasonable for what you receive.

Works Great
It seems that my dealer overfills my car every time I take it in. This works great for taking the 1/2 quart out. 5 Minutes and I am done.

No muss, no fuss
Used it on a 5.7 Mercruiser equipped boat. Was a bit slow, but that might be my technique. Left more oil in engine than I expected but I change oil frequently so I'm not so concerned. Easy to transport and dispose of oil for recycling. Once I use it on our cars and other eqpt. I'll have a better idea of how functional it is. So far I'm satisfied and it seems to be well constructed. I don't anticipate any problems.

This is great
I'd seen this evacuator in some car care catalogs I get, but for around $75 instead of the $52 Amazon charges. I generally am fine with going under the car, but I have an S2000 now and it's too low to go on my ramps. So, I bought this after reading many reviews.

In short, this works great. I got it in 2 days after ordering, and it was in perfect shape. I checked, and there were no cracks or crazing in the plastic where it was screwed together. The translucent plastic also appears to be very thick - I can't imagine the vacuum pump in this ever being strong enough to collapse it, as one review described. I work in an engine laboratory and deal with automotive tools daily - this is as high quality as most other tools you'd find in a professional garage.

I found the instructions to be just fine. They're only one page, but this is a simple device. In short, there are three tubes that come with it. The largest is designed to connect to the evacuator, and the other end connects to either of the smaller hoses. The small hose fit in the dipstick tube on my S2000, and it was easy to push it down to the oil pan. If you do it slowly, you can feel when the hose first touches the bottom of the pan. The engine oil was still warm from my drive home. I removed the oil fill cap on the engine and pumped the handle on the evacuator 10-12 times. The oil began to get drawn into the chamber quickly. I went inside for 5 minutes or so. When I came back out I had about 1.5 quarts of oil removed. I repeated the pump and wait routine twice more. By then I had most of the oil out and it was mostly sucking air. I did one more pump cycle to make sure I'd gotten as much as possible. According to the markings on the tank I had about 4.7 liters of oil, and the engine holds 4.8. There was easily enough left in the oil filter to make up the difference. After refilling and running the engine there was no sign of dirty oil contaminating the clean stuff. I'm confident that this got as much oil as using the drain plug would have.

The best part was that I stayed clean - I did the whole job in my street clothes. Pouring the dirty oil into my recycle container was easy and clean too - the opening has a funnel tip on it so that the oil pours cleanly.

If you can't get under your car easily, or you're just tired of doing that, I highly recommend this tool. Of course, you'll need to be able to get the oil filter off from the top of the engine to do the whole oil change, but if you can, then this beats putting the car on ramps, changing clothes, going under and getting oily, cleaning up, etc. I see this getting a lot of use at my place.
