Found this item works quite well cleaning out old supercharger snout oil and putting fresh oil in. Some folks may already do it this way but just in case thought I would pass along the info. Works well for its intended purpose of cleaning out oil catch cans as well. DoS Fluid Extraction Syringe for Oil Catch Cans
I can't see the DoS link at the office, but whenever I need a bit of suction like this (to empty the brake fluid resivoir, for example), I use a super-sized syringe that I found at an autoparts store near the gas cans. It's used for measuring out oil for 2-stroke engines (to mix w/ gas for weed eaters, etc) and works perfectly for this purpose. When I ripped my engine apart for a supercharger oil service, the snout side was the least of my worries. That oil looked pretty good at 75k miles. It was the water pump side that was nasty.

Worked great on the supercharger on the Benz Monday. Works like a charm changing the oil on the Mini to. Feed the hose in till it hits the drivers side wall of the oil pan slightly jack up the passenger side rear. No need to get under the car. I've used it on the heavy equipment at work and a few other cars. The only ones the supplied tubing has been to small to slide down the dipstick tube has been a few gm cars. But I think a smaller diameter tubing a rubber joint from Lowes would fix that.
