Please pardon my ignorance with this, but is there a supercharger oil for the 55 engine that requires checking or replacement?

I saw something in the Owner's Manaul re this.

supercharger don't have oil...

i think you thinking about "turbo"

Corsa9000

I am talking about the "Factory Approved Service Products" booklet, on page 9 for S-Class(220) it lists:

Supercharger Oil (Engine M113) Mobil Jet Oil II

For other engines such as M111 and M271 engines it lists MB Supercharger Oil, MB part number 000 989 62 01.

Does anyone have any idea what this is?

Thanks.

Viet_Amg408

omg,,why u worry about those stuff..im guessing its the special oil use to lube when assemble the supercharger.. are you doing any repair on your supercharger?

Corsa9000

Repair? Who is talking about repair.

Viet_Amg408

oh...i see.....i guess you just bored huh?

apparently, you cannot actually use it, except when you replace your supercharger. I'm told the supercharger is a totally enclosed system, that you cannot open to change the oil, except by replacing the whole system with a new "dry" one, and that's when the supercharger oil comes into play. I only found that out on the AMG Private Lounge, where AMG will actually answer questions.

hey where's that at? i want to join tooo....

supercharger have oil.

I’ve sourced Exxon Mobil’s Jet Oil II for their refurbishment from this outfit...

care to elaborate?

Corsa9000

This is what I am asking. A Supercharge (Kompressor) is just a set of impellers that rotate to suck in, compress air and force the air into the engine intake for more power. I am not a mechanic but do not think the supercharger needs oil.

However, the MB approved product list in my set of documents lists it as an item. I am just asking if anyone knows what this item is.

Viet_Amg408

you know how a candy bar "made out of certain ingredients" listed in the back ? same *****...

move on man...didn't you read the reply?...

Viet,

You do know that you do not have to read and answer every single post on the Forum, so if you can not contribute anything, let it be and move on dude.......

It seems like you do not understand the post, but I am preaching to the choir.

Over and out.

splinter

You’re correct, Corsa9000.
The impellers themselves require no lubrication, as they do not contact each other and therefore generate no friction between their moving surfaces.

However, the gears at the front of the supercharger do require and have their own self-contained lubricant supply. Thus the specification from MB as to the correct oil specification.

It’s only to be replaced during overhaul, not regularly serviced in the conventional sense.

candy bar what ??? lol nice write up splinter, that's how you answer a question

Viet_Amg408

whatever i'll reply if i want to..yeah you right, i dont' understand your post....because your post lack of common sense..

Viet_Amg408

you don't know what's candy bar is?

JonMBZ

I don't know what you are getting at his questions are perfectly legitimate and I have been asked this question in the past. I knew what he was talking about he gave you proof of it's existence. He just wanted to know more about what it is and if it requires maintenance (seems fair). I don't understand why you are dumping on his tread when you flat out said it doesn't have oil when it does. He also said "excuse my ignorance" in the first place so you shouldn't expect it to contain common sense in which I don't think this is common knowledge in the frist place. Now he among others get to actually learn how the supercharger works you shouldn't be some dismissive when people are taking the time to learn more about their vehicles.

Viet_Amg408

i guess so..next time i'll probably ignore these kind of post....my bad...lolz..

one love...............

See if you can get this link to the AMG Private Lounge thread on Supercharger Oil. It will confirm what others, including me, have said:

Thanks Splinter, very helpful, much appreciated.

dude or whatever you are! you are a MORON and am absolutely positive you don't own a AMG or never will and for that matter any cars over $100k

Fantastic pictures and great mini-synopsis of why AMG superchargers require specific oil types.

in addition:

there generally seems to be some sort of failures on these AMG superchargers regardless if one installs after market pulleys or not. WOW, its amazing to know how some AMG owners don't know AMG supercharger's have replaceable oil.

Supercharger Oil (and other sites as well)

Mobil came out with a 3rd generation oil for the replacement of the Mobil jet oil II and a 4th generation is in the line up.

on the Mobil jet oil 254 (3rd Gen.) the thermal properties has been increased with less thermal breakdowns for higher rpm bearings temps/higher temp gears.

so it is possible to have zero failures on these pulley system(and AMG superchargers) with bearing upgrades and/or proper aviation oil change in these AMG superchargers. The more these AMG superchargers are used for track/drag purposes the sooner or earlier for supercharger oil changes. For those who have never seen a supercharger oil change between 5-10 years; look at the gunk that comes out--that is if your supercharger hasn't already failed! (when the car is tilted or with the supercharger removed the gunk can be seen oozing).

So there is nothing wrong using a 185 pulley kit but, however, with a pulley safety kit to slow and sync the entire pulley system(as a safety net)--and with a upgraded idler 100mm from a 60mm. it seems to work quite well on mine. But i never use my AMG on the track or drag strips. I only use it as a pleasure vehicle and for quick passing on the highways. (my AMG r170.2 was not designed for track purposes).

Bottom line: if you want the longest lived supercharger possible, stick with the AMG pulley. A larger pulley will necessarily shorten the supercharger life. The larger the pulley, the shorter the life.

fwiw, here's a PSE rebuilder, and looks like they use better bearings(?) Seems like if they can replace bearings, somebody else should be able to.

Still kinda pricey, but a lot less than OEM.

Thanks for the necromancy.
