It is the oil that is used in the M113K supercharger for the E55, SL55, CL55 and so forth...

No. There is no recommended service interval, nor are there any MB sanctioned repairs that required draining the fluid. The dealer does not have it and will not order it. They can get fluid for some of their other superchargers, but not the m113k (it's a different fluid).

Several months back there was a lengthy thread on care and feeding of M-B superchargers.
Turns out there are two different superchargers, depending which car you have. And they use different lub oil.
Also it included diy about how to change supercharger oil.

better quesiton is where the **** do I get the syringe and tube needed to empty the charger? I'm too lazy to hop from store to store, I'd rather get that stuff online....

I used this product from Amazon: "Karlling 150ML Large Big Plastic Hydroponics Nutrient Measuring Syringe". It's a large syringe with measurements (in ml) and a long flexible tube. It makes the job quick and easy. Just be extra careful not to drop the plug for the supercharger and don't overfill it (measure how much fluid you take out and add that much; it does NOT get filled until it overflows out the hole and unless you take the supercharger off to thoroughly drain it, you will not get all of the fluid out so you can't fill it with any known capacity).

It may work but that's over full. This has been discussed here before at length. Even when level, the fluid should not be up to the fill plug. With it over full you risk it leaking out the shaft seal.

Aware on just replacing the amount I take out and the screw. Stupid how there's no replacement for it...

Yeh, I know. I've read all the treads, built a supercharger out of pieces of two, had it apart again for some minor porting and painting. The plug looks like a reasonable fill level to me, like it was designed that way. Common sense also tells me It's not lifetime lubricated. At least not the life I'm hoping for! The risk of some oil leaking out is not the biggest gamble I've ever taken. After two years and many many miles I'm confident my SC has enough oil in it. Not enough is a real problem.

Too little oil is bad, but so is too much. The correct fill level is 150 ml, but you will probably not be putting this much in if you suck it out with a syringe (you won't get 100% of the oil out). If the oil is too high it will increase drag (at the speed supercharger gears run, that equates to a measurable amount of horsepower being lost). This also results in excessive oil temperature and foaming/aeration of the oil, which will significantly reduce the lubricating ability.
Also, keep in mind that this oil level is specified for the factory rpm and boost level (which many of us are exceeding). Some supercharger manufacturers actually recommend lowering the oil level when increasing boost (although I would stick with the specified 150ml in our applications). For example, Kenne Bell recommends lowering the oil level by up to 1/4" when running high boost (explaining that this will significantly reduce oil temperature and reduce power loss by 15HP at 18,000 rpm vs the normally specified level). They also state that overfilling is the most frequent cause of supercharger failure (due to the resulting heat). By my calculations, 15 horsepower is equivalent to over 7 space heaters on high (11,000 watts); you probably don't want all that heat in your supercharger oil (and that's at the normal recommended fill level, we're not even talking about over-filling).
(As far as too little oil, I wouldn't worry too much: as long as the gears are partially submerged, they should be well lubricated. If the fluid level is completely below the gears, you will definitely have problems, but that would take an egregious measuring error.)
While it's unlikely that you will notice much of a difference if slightly over-full or under-full, as long as you're going through the effort to change the fluid, you might as well do it right.
