Average Reviews:
(More customer reviews)I bought this Mityvac 7300 because I usually get sick when I crawl under my cars to change the oil. Since my 2007 Huyndai Santa Fe has the oil filter on top of the engine I figured I was all set. I have a Nissan Frontier as well and that filter is accessible only from below unfortunately. Perhaps limited time under one vehicle only will let me escape without getting sick, I hoped.
The Mityvac's directions are not clear. The parts described in the verbiage are not pictured nor are they intuitive. You do not know what they are. For instance the instructions say to shut off a valve to build a vaccum in the unit, disconnect the air compressor and use the Mityvac in some remote location away from the air source. Great news, except the valve is neither described nor is it provided. For the life of me I cannot figure out how to make that feature work, but that was ok since I used the Mityvac where the air compressor was located.
Before my first use I bought a 25 foot coil of 1/4" plastic tubeing (which was intended for refrigerator ice maker hook up) at Home Depot as a previous reviewer suggested. The provided tubing is too short. I used about 12 foot of tubing. It worked beautifully, but you must insure that you have the tube all the way down to the bottom of the oil pan. I did not at first and did not fully evacuate the Santa Fe.
After evacuating the Santa Fe I turned to my Nissan Frontier and prepared to change its oil as well. That is when I ran into problems since I had not emptied the Mityvac before using it on the Frontier.
DO NOT COUNT ON THE OVERFLOW SHUTOFF TO WORK! I did and mine did not. Soon oil was all over the floor. Of course if a person is attentive and watches what is happening this would not happen. It remains to be seen if any injury occurred to the venture part when the oil got sucked down into it.
To clean the unit when I was done I used hot water with dish washing detergent. It worked well enough.
All in all I am pleased that I bought the Mityvac 7300. Except for the overflow protection failure, it worked quite well. I would not suggest changing oil wearing a tuxedo as some have implied could be done, however, unless you are into destroying tuxes. It simply is not THAT clean a procedure.
