It frustrates me that a small amount of dirty oil remains in the engine during an oil change. I once saw on the net, a device which allows you to completely evacuate all the old oil from the system but for the life of me I can’t remember the name of it or who manufactures it. Must be old age and a failing memory.
The device mounted to the oil filter housing once the filter was removed. After draining and re-filling the oil tank with fresh fluid, you would turn the engine over several times and pump old oil out through a plastic tube attached to the device. Then remove the device, install a new filter, and top off the oil tank.
Does anyone know of this device? Who manufactures it? Have experience with it? Or know of any other tricks to completely evacuate the system of oil?

a little dirty oil is a lot better than the dry sump you will have with a completely evacuated engine.

 

2003springer. your reservoir stays full your just chasing the 32 oz of chit oil out of the bike with clean oil. nothing gets starved or runs dry..

 

I checked it out and I LOVE IT!!! Makes perfect sense, but the only thing to it, really (for Twin B) is the oil filter blank. Could we not make one from an old filter? I mean, cut it down short, weld it back and use that? Or possibly a threaded rig with a hose to turn the oil coming out back into the engine, which is all this thing could possibly be doing. The scavenge end is easy: just some vinyl hose, and hose barb adapters, a reducer maybe.
Even on my car and truck I let the oil drain overnight sometimes to fully get as much crap out as I can. Oil is cheaper than parts.

Milty,

Yes, this is the item I've been looking for. Thanks.

 

mine looks clean even without draining the sump

 

Makes me wonder how dirty are you letting your oil get that you worry about a little left over.

 

Actually, that's a really good point, considering that oil never wears out. It gets diluted or polluted, and on overheat the additives break down, you get acids from cold oil (idling) and carbon from mileage. The oil in those vids would never be found in ANY machine of ANY type of mine, including the lawnmower.

The question here is how many more miles are you gonna get out of the engine vs. how many of those 32 oz. buckets of expensive synthetic oil? If you don't let oil get really dirty, I'll wager it's not much.
