its a bit messy when you suck it out of the collection tank outside restaurants, which I do from time to time but I have an old ford pickup with a flat bed and a couple 55Gal drums mounted to it.. so i dont really care if I drip a bit of grease all over it.. However the majority of the oil I use is via a systemI have setup with a local chinese restaurant where they drain the used cooking oil into the containers the new oil comes in, then when they refill, they save the containers for the next oil change, fill them up and then they call me and I pick them up.. they are pretty nice ( the containers) .. 5 Gal pails with screw on lids and carry handles. With this method you could pick them up in the nicest of cars in the trunk.. (maybe a bit of plastic tarp down first, just in case)
but for my pickup and filtering mechanisim, I use marine baitwell pumps (the four piston chamber variety) they are self priming, fairly powerful, and the grease does not bother them too much. I pump/pour the raw oil into the first of three drums, thru a stack of fine screen to get the big chunky bits, then pump into the second drum thru 30 micron racors, then into the final drum thru 10 micron racros, and before it goes into the car/boat/tractor/engine driven welder/truck/whatever it goes thru a set of 2 micron racors.
I am currently shopping for a 99 E class turbo diesel or a 96 non-turbo E class to put the wife in..and cannot wait to get rid of the gas sucking 2004 ford..then I will be all diesel ( er WVO.. ) then the collection and processing really starts to pay off..
