I changed the sc oil today and got very little out, maybe 20cc with syringe. Figured I just wasn't getting the tube to the bottom. When I went to refill it drank six times that much and still not overflowing the drain. I got nervous and came in for a more extensive search. That didn't help, there is conflicting information. Some say fill to the plug like a diff, someone else said that's not right it will be overfull which is BAD. Does anyone know for sure?

i would like to know me too

they dont take much but you cant over fill it... its full ones oil starts to come out. Same exact as doing a differential, except here its one hole to drain one to fill vs diff one to fill one to drain.

keep on adding until it starts to come from form the inlet

If you look at your supercharger, the back of the unit sits lower than the front of the unit.

To level it out, drive your rear tires over some 2x6 wood planks in a ramped fashion so your supercharger is flat to the ground. Or another option, if you have a slightly sloped driveway is to point the front of your car towards the street and back it up over a 2x6 piece of wood to try to level up the supercharger.

If the supercharger isn't totally level, and you can potentially overfill it. Even then, I think your car will spray out excess oil via a vent hole, although don't quote me on that (some supercharger designs allow for this--but not 100% sure on our E55 AMG).

I used Mobil1 Jet II Turbine oil, which is the factory fill:

I jacked up the rear of my car and let it sit overnight when I recently changed my SC oil. The volume of oil I extracted was close to 140 ml. The SC oil is very thin with a very low viscosity so will drain forwards to the plug.

I remember our friend's "nidyanazo" done that in his CL55K,,


ZAYED,,

Ok, filled-ran-drained-filled a couple times, and it was much cleaner the third time. (got better at draining it too!)


Thanks for the conformation guys, I filled it to the cork.


Based on the level and condition of my fluid at 78000 I would say this is "must do" maintenance. Might be too little too late for me.

Filled-ran-drain ?

Is this the normal process or that's what you did ?

Don't the oil change usually dictate - drain-replace and drive on ?

The fill level is 150ml. I don't remember exactly where I have seen this documented. I'll see if I can dig it up. I have changed my oil three times. First at 145,000 miles (oil was extremely dirty and dark) ran it for a week, changed it again (much cleaner but still pretty dirty) ran it for another week and changed it a third time ( much much cleaner this time). Each time, I suctioned out as much as I could and put 150ml in and it never poured out the hole.

Did you level the supercharger?

I tried using the syringe method and failed miserably...I'll have to try to level out the car on a sloped driveway. I saw the video on it but I don't get very much at all when attempting to drain it. I'll give this a go at the end of the week.

Is there anyway to angle the end of the tube down? Perhaps fishing line to pull it down? Or am i just overthinking this?

StarvingArtist

A piece of wire in the tube might help. Aim down and to the left. You may not have much in it, I certainly didn't.

StarvingArtist

It was dirty and I had plenty of oil, as for normal... I lost track of that years ago.

Maybe there's nothing else in there.I currently have my sc off and drained it and not much came out.

How long does it take to change the SC oil?

I wonder if MIL-L-23699 turbine oil would work (not that I would use other than what's recommended). Some of you Military Aircraft Mechanics might know what I'm talking about.

If you are being super careful and have the proper tools in place (~50cc syringe, aquarium air tube, Mobil1 Jet II fluid, 5mm ball hex tool, and Teflon tape), you're looking about 20 minutes for a suction out and refill. The hardest part is making sure you don't lose the plug screw when taking it out and putting it back in. When suctioning out the fluid, try to get your tube towards the back left and down to get into the reservoir.

For the fluid, it's $15/quart + shipping for the factory fill (see links earlier in thread).

While your suggested turbine oil may work, for the price, I'd stick with what you know works.

Just a little update.
Did this last year first time first replaced the bearing still weird noise when operating temperature until saw this thread bought refill kit from Powerhouse comes with 2 syringes
2 x tubes and 2 x 140ml supercharger oil cheap and fast delivery.
Removr the plug nothing came out was bone F dry lol these Superchargers are STRONG I tell u 180.000 km and never changed anyway did it again yesterday and again this morning decided raising rear of car just so the wheels can spin freely..
Now this time I got the tube in a very different way drained 2 syringes aprox 150 ml.. black as the night
Lowered and raised front filled it up little over 150 ml no problems but one need be sure to when draining it get the tube in correctly I had to try many times before and I see now this is important else u won't get much out...

Spins like a ***** cat

If you look at the location of the allen drain plug, nothing is supposed to come out when you remove it (just don't lose it or drop it). Lower 1/3 of the gears are supposed to sit in the oil. What the above photo doesn't show is the matching gear on the supercharger itself.

If you're changing out this oil for the first time, the idea here is to "flush" it considerably. I ended up going to the airport and found someone with the Jet Oil II (no one had the Jet Oil 3, and considering how robust this oil is I stayed with the "stock" oil).

You can do as many as 3-4 flushes --- chemical nausea depending --- would highly recommend doing this outside.

Put your pump hose down into the hole, and try to position it so that it does give you some quantity (100ml or more). Then fill with 150-180 ml.

Drain again. Should be very easy to get it all out, and you should get more than what you put in (keep track). The idea is to dilute the original oil to almost nil, and by the time you get to the third or fourth flush the color will no longer be blackish, but will be more like the color of the oil going in.

At that point, pull out as much as you can and put in exactly 150ml. The maximum is 180ml, at which point it will seep out of the bolt in the middle of the above photo (which you don't want).

Good stuff brother ggood stuff.
Here you also have absolutely level is not level sitting on the engine but still perfect information and STILL better undertill than overfill my point was more it is very much possible you won't get all out if hose is not position correctly but with the Eaton supercharger refills kit from power house the hose comes in such a length is perfect u know when is in the right way..

Anyway much appriciated picture thanks again

Here is an excellent tutorial. It seems that most people don't get their tube all the way down into the oil. Remember NOT to fill until it overflows from the drain/fill opening. You will put less than 150 ml back in as 150 ml is the MAX for a dry fill from new.
