Review on Efficient Oil Extractor: Stens 051-703 - Simplify Oil Changes and Maintenance by Douglas Norton

I ordered this a few months ago and have used it to change the oil in my cars as well as some friends so have had many opportunities to try it. EVERY pump makes the process easy, quick and clean. You just gently and slowly insert the dip tube into the dipstick tube until you feel it making contact with the oil pan (something newbies should be careful about. You don't want to go any further or the tube could get stuck). which can add a lot of time and clutter to the whole process). The advantage of the LiquiVac is that I can remove the hose from the unit, close the lid and put it right in the trunk to take the oil to the shop for recycling. Confusion when pumping from pump to tank. Neither Pella nor Mightvac - the other brands I looked at - would stay airtight in the trunk. Before purchasing, my biggest concern was the pump's ability to pump all the oil out of the engine. Rest assured, there is no significant difference between the amount of oil you remove through the drain and the amount you siphon with the pump. Keep in mind that high end dealers and high paid professionals change oil this way so it's clear enough for street use!
